Why this page exists
Risk in Tennessee is not one thing. It depends on where you are.
Tennessee stretches 440 miles from the Great Smoky Mountains to the Mississippi River, crossing three distinct geological divisions. A household in Memphis prepares for earthquakes and river flooding. A household on the Cumberland Plateau prepares for ice storms and wildfire. A household in Nashville prepares for tornadoes, severe storms, and extreme heat. The preparations overlap, but the priorities do not.
This page helps you identify which hazards and disruptions are locally relevant, understand how risk changes across the state, see which times of year deserve closer attention, and build a household plan around what is actually likely where you live. It focuses on warning systems, household continuity, cascading failures, and recovery. For land, water rights, growing conditions, and property due diligence, see the main Tennessee guide.

Statewide baseline
Ten preparations that address several Tennessee hazards at once.
These are not generic kit items. Each one connects to actual Tennessee risks and addresses more than one hazard.
A NOAA weather radio with alarm mode, kept on the nightstand. Tennessee leads the nation in nighttime tornado fatalities. Outdoor sirens are not designed to wake people in sealed homes. A weather radio set to alarm mode is the only reliable overnight alert. It also alerts for flash flooding, severe thunderstorms, and winter storms.
County alert enrollment. Enroll in your county emergency notification system for location-specific warnings beyond Wireless Emergency Alerts. This gives you a second, independent warning channel.
A practiced tornado shelter plan for every household member at every regular location. Home, work, school, and a plan for when in a vehicle. Manufactured-home residents need a pre-identified hard shelter within walking distance.
Stored water that does not depend on grid power. At least three days (one gallon per person per day). Rural well-dependent households should store more, since power outages stop the pump.
A backup lighting and device-charging method. Battery-powered lanterns and a portable battery bank cover multiple scenarios: ice storms, severe weather outages, post-tornado displacement.
A backup heat source if you heat with electricity only. Ice storms, winter storms, and severe cold can cause multi-day outages. Identify and test a safe backup before winter.
Flood zone awareness for home and travel routes. Check whether your home and regular travel routes cross a mapped flood hazard area. Tennessee flash flooding kills in mountain hollows, low-water crossings, and urban areas alike.
A household communication and reunification plan. When family members are separated at work, school, or caregiving, include an out-of-area contact who can relay information if local calls fail.
Current medication list and portable documents. Keep a current medication list, two weeks of essential medications, and copies of critical documents in a portable location. Tornado or flood displacement may last days or weeks.
Insurance that matches your actual risks. Standard homeowner policies exclude flood and earthquake damage. Verify that flood and earthquake riders are present or consciously declined, and review hail and wind deductibles.
Hazard profile
What can happen, where it matters, and your first decision.
Each row connects a Tennessee hazard to where it matters, when it matters, how warnings arrive, what it disrupts in your household, and your first planning decision. Full during-event protocols link to the national hazard guide.
| Hazard or condition | Where it matters | Higher-attention period | Warning character | Likely household disruption | First planning decision | Full guide |
|---|---|---|---|---|---|---|
| Tornadoes | Statewide, highest activity in Middle TN. Dixie Alley corridor. | March through June; secondary peak November through December. Can occur any month. | Minutes to tens of minutes. Frequently rain-wrapped and fast-moving. High proportion occur at night. | Structural damage, displacement, power loss, road blockage, injury | Where is your shelter at home, work, school, and in a vehicle? | Tornadoes |
| Flash flooding | Statewide. Mountain hollows, low-water crossings, urban areas, and small watersheds. | Year-round, peak March through September | Minutes. Flash Flood Warnings. Can develop faster than warnings reach some areas. | Road impassability, vehicle loss, structure flooding, water contamination, fatality risk at crossings | Do any of your regular routes cross low-water crossings or mapped flood areas? | Flooding |
| River flooding | Major river corridors: Mississippi, Tennessee, Cumberland, and tributaries | Late winter through spring; tropical remnants in fall | Hours to days. River Flood Warnings from NWS river forecast centers. | Extended road closures, agricultural loss, structure flooding, displacement, utility disruption | Is your property or route in a mapped river flood zone? | Flooding |
| Severe thunderstorms | Statewide | March through November, peak spring | Minutes to hours. Warnings for wind, hail, or isolated tornadoes. | Hail damage, downed trees, power outages, roof and vehicle damage | Is your roofing rated for hail impact? Are trees near power lines or structures? | Severe storms |
| Ice storms and winter weather | Statewide, most severe on Cumberland Plateau and in East TN mountains | December through February | Days of advance forecast. Winter Storm Warnings and Ice Storm Warnings. | Extended power outages, road impassability, heating failure, water system failure, isolation | Do you have a backup heat source and stored water that work without electricity? | Winter storms |
| Earthquakes (New Madrid) | West Tennessee (directly on the zone). Shaking felt statewide in a major event. | No seasonal pattern | No advance warning. ShakeAlert does not cover the eastern U.S. | Structural damage, utility failure, bridge and road damage, liquefaction near Memphis, long recovery | Do you have earthquake insurance? Is your home unreinforced masonry? | Earthquakes |
| Wildfire | East Tennessee mountains and the wildland-urban interface near the Smokies | October 15 through May 15 (Tennessee fire season). Peak during fall drought. | Hours to days when wind-driven. Red Flag Warnings from NWS. Evacuation orders from local agencies. | Evacuation, structure loss, smoke exposure, road closure, extended displacement | Is your property in a wildland-urban interface area? Is defensible space maintained? | Wildfire |
| Extreme heat | Statewide, worst in urban areas (Memphis, Nashville) and lowland corridors | June through September | Days of forecast. Heat Advisories and Excessive Heat Warnings. | Health risk (especially for older adults, outdoor workers, and people without air conditioning), cooling cost surge, power grid stress | Where is your nearest cooling center? Can your household sustain cooling without grid power? | Extreme heat |
| Landslides and slope failure | East Tennessee mountain terrain, steep hollows, and road cuts | During and after extended rainfall or rapid snowmelt | Limited. Often occurs without specific advance warning. | Road loss, access isolation, structure damage, utility disruption | Is your property on or below a steep slope? Is your access road vulnerable? | Landslides |
| Drought | Statewide, periodic | Summer and fall | Weeks. U.S. Drought Monitor updates weekly. | Well drawdown, water-use restrictions, wildfire risk increase, agricultural loss, burn bans | Does your water supply depend on a shallow well or small spring? | Drought |
Operational risk regions
What you prepare for depends on where in Tennessee you live.
These operational regions group counties by shared hazard patterns and infrastructure. They are not the land-search regions from the main state guide.
West Tennessee (Mississippi Corridor and Lowlands)
Shelby, Tipton, Lauderdale, Dyer, Obion, Lake, Weakley, Henry, Gibson, Crockett, Haywood, Madison, Carroll, Henderson, Chester, Hardeman, McNairy, Hardin, Decatur, Benton, and Fayette counties.
Primary concerns: New Madrid earthquake zone (directly beneath), Mississippi River flooding, tornadoes (open terrain with limited visual warning), severe storms, and extreme heat in the Memphis metro.
Infrastructure considerations: Bridges over the Mississippi are limited and would be compromised in a major earthquake. Memphis infrastructure is largely not designed for seismic loads. Soil liquefaction is a documented risk along the river corridor.
Verify locally: Earthquake insurance status. Whether your home is unreinforced masonry. Whether your route crosses Mississippi River bridges or flood-zone roads. County alert enrollment.
Middle Tennessee (Nashville Basin and Highland Rim)
Davidson, Williamson, Rutherford, Wilson, Sumner, Robertson, Montgomery, Cheatham, Dickson, Humphreys, Maury, Marshall, Bedford, Coffee, Cannon, DeKalb, Smith, Trousdale, Macon, Clay, Jackson, Putnam, Overton, and surrounding counties.
Primary concerns: Tornadoes (highest activity zone in the state, including nighttime tornadoes), flash flooding (the 2010 Nashville flood and the 2021 Waverly flood both occurred here), severe thunderstorms with large hail, and extreme heat in the Nashville metro.
Infrastructure considerations: Nashville's rapid growth means more people in hazard zones. Flash flooding in small watersheds develops faster than warnings can reach some areas. Hail regularly damages roofing and vehicles.
Verify locally: Whether your home and regular routes cross mapped flood areas. Tornado shelter plan for every location. Hail and wind deductibles on your insurance. County alert enrollment.
Cumberland Plateau and Upper Cumberland
Cumberland, Fentress, Pickett, Scott, Morgan, Bledsoe, Van Buren, Grundy, Sequatchie, White, Warren, and surrounding counties on the plateau.
Primary concerns: Ice storms and winter weather (the plateau collects ice at higher frequency than surrounding lowlands), flash flooding in gorges and narrow valleys, wildfire during drought periods, and limited road access during weather events.
Infrastructure considerations: Rural power lines through timber are vulnerable to ice loading. Limited alternative routes when primary roads are blocked. Well-dependent water systems lose function during power outages.
Verify locally: Backup heat and water that work without grid power. Alternative access routes if your primary road is blocked. Whether your property is in a wildfire interface area. Generator safety plan if applicable.
East Tennessee Mountains and Valleys
Knox, Blount, Sevier, Cocke, Greene, Hawkins, Sullivan, Washington, Carter, Unicoi, Johnson, Hamblen, Jefferson, Grainger, Claiborne, Campbell, Anderson, Loudon, Monroe, McMinn, Polk, Bradley, Hamilton, Marion, Meigs, Rhea, and Roane counties.
Primary concerns: Wildfire in the wildland-urban interface (the 2016 Gatlinburg fire killed 14 and destroyed over 2,000 structures), flash flooding in mountain hollows (Hurricane Helene in 2024 demonstrated how mountain valleys funnel floodwater in the Tri-Cities area), ice storms and winter weather at elevation, and landslides on steep terrain.
Infrastructure considerations: Mountain roads are vulnerable to landslides, flooding, and ice. Many communities have limited evacuation routes. The wildland-urban interface near Gatlinburg, Pigeon Forge, and the Smokies puts residential and tourist areas adjacent to fire-prone forest.
Verify locally: Wildfire defensible space around your property. Evacuation routes and whether you have more than one way out. Slope stability if building on a hillside. Flash flood exposure in hollows. Winter supply depth for elevation.
Southern Middle Tennessee (Alabama Border)
Franklin, Lincoln, Moore, Giles, Lawrence, Wayne, Lewis, Perry, and Hickman counties.
Primary concerns: Tornadoes (this corridor receives tornado activity from both northwest and southwest tracking systems), severe storms, and flooding along the Elk River and Duck River. NWS Huntsville, Alabama, issues warnings for Franklin, Lincoln, and Moore counties rather than the Nashville office.
Infrastructure considerations: Rural, with long distances to hospitals and emergency services in some areas. Some communities served by a different state's NWS office, which can create confusion during events.
Verify locally: Which NWS office issues your warnings (Nashville or Huntsville). NOAA Weather Radio transmitter frequency for your area. County alert enrollment. Distance to nearest hospital and alternate route if primary is blocked.
Seasonal readiness
A Tennessee household readiness calendar.
These periods deserve additional attention. No hazard is impossible outside its typical season.
| Season | Higher-attention hazards | Household tasks |
|---|---|---|
| January through February | Ice storms, winter storms, severe cold. January 2026 Winter Storm Fern hit 29 counties. | Test backup heat source. Verify stored water. Check pipes and insulation. Keep vehicle fuel above half. Review ice storm power-outage plan. |
| March through May | Tornadoes (peak season), severe thunderstorms, flash flooding, river flooding. Secondary tornado peak may begin in November. | Review and practice tornado shelter plan. Confirm NOAA weather radio batteries and function. Enroll in county alerts. Check flood insurance status. Clear debris from drainage. |
| June through August | Extreme heat, severe thunderstorms, flash flooding. Heat index regularly exceeds 100 in Nashville and Memphis. | Check cooling systems. Know your nearest cooling center. Monitor heat advisories. Stay aware of flash flood potential during heavy rain. Maintain hydration and check on neighbors. |
| September through October | Tropical remnants (flash flooding), drought, wildfire season begins October 15. Fall severe weather can produce tornadoes. | Review fire season awareness if in East TN. Clear brush and maintain defensible space. Monitor drought conditions for well-dependent households. Prepare winter backup heat. |
| November through December | Secondary tornado season, winter storm transition, wildfire season continues, early ice events. | Test backup heat and stored water before first hard freeze. Confirm weather radio is working. Review insurance before year end. Check tire condition and vehicle emergency kit. |
Cascading disruptions
How one failure leads to the next.
These cascading chains are characteristic of Tennessee. Each has happened. Understanding the sequence helps you prepare for the second and third consequences, not just the trigger.
Ice storm chain
Ice accumulates on trees and power lines → widespread power outages lasting days to weeks in rural areas → electric heat fails → well pumps stop (no water) → pipes freeze and burst when power returns → road impassability delays utility crews and isolates households.
Preparation that reduces the consequence: Backup heat that works without electricity; stored water; pipe insulation and shutoff knowledge; alternative access route awareness.
Nighttime tornado chain
Tornado strikes after midnight → occupants asleep with phones silenced → outdoor sirens not heard inside sealed homes → no shelter action taken → structural damage or injury → power loss and road blockage prevent immediate response → displacement with no documents or medication.
Preparation that reduces the consequence: NOAA weather radio with alarm mode on the nightstand; pre-identified shelter in every home; portable documents and medication kit.
Flash flood chain (mountain terrain)
Heavy rain over steep mountain watershed → water funnels into narrow hollows faster than warnings can reach residents → roads wash out → communities isolated with no way in or out → cell towers lose power → emergency services cannot access affected areas → contaminated water supply if well or spring is flooded.
Preparation that reduces the consequence: Know whether your home or route is in a flood-prone hollow; multiple communication methods; stored water and supplies for extended isolation; alternative route planning.
Wind-driven wildfire chain (East Tennessee)
Extended drought dries forest fuel → ignition source (human or natural) → high winds drive fire across steep terrain faster than suppression can contain it → embers travel up to a mile, igniting structures in the wildland-urban interface → evacuation routes become limited single-lane mountain roads → power lines burn, cutting electricity → smoke reduces visibility to near zero.
Preparation that reduces the consequence: Defensible space; multiple evacuation routes identified in advance; go-bag ready; NOAA weather radio for Red Flag Warnings; awareness of fire season (Oct 15 through May 15).
New Madrid earthquake chain (West Tennessee)
Major earthquake on the New Madrid Seismic Zone → structural damage to unreinforced masonry buildings → soil liquefaction along river corridors → Mississippi River bridges damaged or impassable → gas and water line breaks → extended utility outages across a multi-state area → overwhelmed mutual aid because damage extends across multiple states simultaneously.
Preparation that reduces the consequence: Earthquake insurance; water heater and heavy furniture secured; stored water and supplies for extended self-sufficiency; alternative routes that do not depend on river bridges.
Household situations
What changes for your household.
These situations change which risks matter most and what you should verify first. Each module answers: what changes, what to verify locally, and your first practical improvement.
Manufactured-home residents
Manufactured homes are vulnerable to tornado and severe wind damage at lower wind speeds than site-built homes. Tennessee's tornado frequency, including nighttime tornadoes, makes this a priority. Verify: location of the nearest hard-shelter structure you can reach on foot. First improvement: identify and practice reaching that shelter in darkness.
Renters and apartment residents
Renters may not control building maintenance, insulation, or tree removal. Interior apartments may have no basement. Verify: building tornado shelter location (interior hallway, lowest floor); whether your renter's insurance covers flood and displacement. First improvement: county alert enrollment and a NOAA weather radio.
Rural private-well households
Any power outage stops the well pump. Ice storms and winter storms can cause multi-day outages in rural Tennessee. Verify: well depth, pump type, and whether a hand pump or generator is feasible. First improvement: store at least five days of water (more than the standard three, given rural outage length).
Electric-only heat or cooking
All-electric homes lose heating, cooking, and water heating during a power outage. Ice storms are the primary risk. Verify: that your backup heat source is safe for indoor use, properly vented, and has fuel. First improvement: test the backup before the first cold snap of the season.
Older adults and people living alone
Extreme heat, extended power outages, and post-tornado displacement are higher-consequence for people who live alone or have limited mobility. Verify: that someone checks on you daily during extreme weather events. First improvement: establish a mutual check-in arrangement with a neighbor, family member, or community group.
People with mobility, sensory, or medical needs
Evacuation from a tornado shelter, flooded area, or fire zone may require assistance. Electrically powered medical equipment fails during outages. Verify: that your utility company has you on a medical priority list for restoration. First improvement: battery backup for essential medical equipment and a plan for reaching shelter without assistance if needed.
Pets, service animals, and livestock
Pets and livestock cannot be left behind during evacuation from tornado, wildfire, or flood. Public shelters may not accept animals. Verify: pet-friendly shelter options or boarding arrangements. First improvement: pre-pack an animal go-bag with food, water, leash, carrier, vaccination records, and medications.
Households without vehicles
Evacuation from flash flood, wildfire, or tornado without a vehicle requires advance planning. Public transit may be suspended during severe weather. Verify: whether your county emergency plan includes transportation assistance. First improvement: identify a neighbor, friend, or community resource who can provide evacuation transportation.
Warning systems
How warnings reach your household.
The information chain runs from federal detection through your household decision. Understanding each layer helps you identify which links you control and which you need to add.
Detection and forecast
The Storm Prediction Center in Norman, Oklahoma, issues severe weather outlooks and tornado/severe thunderstorm watches. NWS forecast offices issue warnings for their county warning areas. The USGS monitors seismic activity. The Lower Mississippi River Forecast Center and Ohio River Forecast Center provide river stage forecasts.
NWS offices serving Tennessee
Five offices issue warnings for Tennessee counties: Nashville (38 Middle Tennessee counties), Morristown (33 East Tennessee counties, including Chattanooga and Knoxville), Memphis (West Tennessee), Huntsville, Alabama (Franklin, Lincoln, and Moore counties), and Paducah, Kentucky (NOAA Weather Radio coverage to parts of Henry and Weakley counties). If you live near a state border, verify which office serves your county.
Warning types to understand
Outlook: conditions may develop over the next several days. Watch: conditions are favorable; be ready to act. Warning: the hazard is occurring or imminent; take action now. Flash Flood Emergency: a rare, particularly dangerous situation with a severe threat to human life. Evacuation order: leave the area immediately. Official instructions during an event always supersede general preparedness guidance.
How warnings reach you
Wireless Emergency Alerts (WEA): automatic to capable phones, no enrollment needed, but limited geographic precision and may not wake you. NOAA Weather Radio: continuous broadcast with alarm mode that activates for your county's warnings; the only reliable overnight alert. County alert systems: location-specific notifications by phone, text, or email; requires enrollment. Outdoor warning sirens: designed to alert people who are outdoors; not designed to wake people inside sealed homes. Do not rely on sirens as your primary indoor alert.
Your household decision
Redundancy matters. No single warning method is reliable in all conditions. A Tennessee household should have at minimum: a NOAA weather radio with alarm mode, county alert enrollment, and Wireless Emergency Alerts enabled on every household phone. Three independent channels means a failure in one does not leave you unaware.
Prepare, endure, recover
The three phases of household readiness.
Prepare
Actions you can complete before the higher-attention season or within the next month:
- Get a NOAA weather radio with alarm mode and program it for your county.
- Enroll in your county emergency alert system.
- Choose and practice your tornado shelter plan at every regular location.
- Store at least three days of drinking water (one gallon per person per day).
- Identify and test a backup heat source before winter.
- Check flood zone maps for your home and travel routes.
- Review your insurance: verify flood and earthquake riders are present or consciously declined.
- Assemble portable documents and a current medication list.
- Set a household communication and reunification plan.
- If in East Tennessee: clear defensible space around your property before fire season (October 15).
Endure
Household continuity decisions during the disruption. Follow official instructions first; these are supplementary considerations:
- Monitor your NOAA weather radio and county alerts continuously during an active event.
- If a tornado warning is issued, move to your shelter immediately, regardless of time of day.
- Never drive through floodwater. Turn around, don't drown.
- During a power outage: keep refrigerator and freezer closed, use stored water, avoid carbon monoxide from generators or heating devices used improperly indoors.
- During extreme heat: move to a cooled location, stay hydrated, check on neighbors and older adults.
- If ordered to evacuate for wildfire or flood, leave immediately with your go-bag, documents, medications, and animals.
- For detailed during-event protocols, see the full guide for each hazard linked in the table above.
Recover
First recovery steps after the immediate danger has passed:
- Do not return to a damaged structure until it has been inspected and cleared.
- Document all damage with photographs before cleaning or moving anything. This supports insurance claims and FEMA assistance applications.
- If a federal disaster declaration is issued, register at DisasterAssistance.gov or call 1-800-621-3362.
- Contact your insurance company promptly. Keep records of every conversation.
- Be cautious with contractors. Verify licensing and references before signing any contract. Tennessee requires contractors to be licensed for projects over $25,000.
- Use Tennessee 2-1-1 (211.org) for disaster recovery, housing, food, and human services referrals.
- Monitor water quality advisories. If your well or spring was flooded, have the water tested before using it.
Ten-action checklist
Ten high-value actions for Tennessee households.
Each action is specific, achievable, addresses multiple Tennessee hazards, and is free or low-cost when a reasonable option exists. Work through them in order.
- Get a NOAA weather radio with alarm mode and program it for your county. Tennessee leads the nation in the proportion of tornado fatalities that occur at night. This is the single most important piece of preparedness equipment for a Tennessee household.
- Identify your NWS forecast office and enroll in your county emergency alert system. This gives you two independent warning channels beyond Wireless Emergency Alerts and the weather radio.
- Choose and practice your tornado shelter plan for every household member at every regular location. Home, work, school, and a plan for when you are in a vehicle. If anyone lives in a manufactured home, identify a hard shelter within walking distance.
- Check whether your home and two ordinary travel routes cross a mapped flood hazard area. Use FEMA's flood map service or your county floodplain manager. This also informs your insurance and route decisions.
- Store at least three days of drinking water. One gallon per person per day. Rural well-dependent households should store five days or more, since ice-storm outages can last longer.
- Establish a backup lighting and device-charging method that works without grid power. Battery-powered lanterns and a portable battery bank are a minimum. Covers tornado aftermath, ice storms, and any extended outage.
- If you heat with electricity only, identify and test a backup heat source before winter. The January 2026 winter storm hit 29 counties and triggered a federal disaster declaration. Ice storms can leave rural areas without power for days.
- Review homeowner or renter insurance: verify that flood and earthquake riders are present or consciously declined. Standard Tennessee policies exclude both. Hail and wind deductibles vary and deserve review, given the state's severe thunderstorm frequency.
- Set a household communication and reunification plan for when family members are separated. Include an out-of-area contact who can relay information if local calls fail. Practice it once.
- Keep a current medication list, two weeks of essential medications, and copies of critical documents in a portable location. Displacement after a tornado, flood, or wildfire may last days or weeks. These items are difficult to reconstruct from a shelter.

What Tennessee has learned
The nighttime tornado lesson: warnings only work if they wake you up.
At 12:32 a.m. on March 3, 2020, an EF3 tornado touched down in Nashville. It crossed North Nashville, East Nashville, and Donelson before continuing 60 miles east to Cookeville, where an EF4 killed 19 people. Six people died in Nashville. Most were asleep when the tornado struck.
The warnings were issued. Outdoor sirens sounded. But outdoor sirens are designed to alert people who are outdoors. At 1 a.m., in sealed homes with phones on silent, many people never heard the warning.
The decision that mattered was not whether to shelter. It was whether the household had a warning device capable of waking people from sleep. A NOAA weather radio set to alarm mode on the nightstand would have activated automatically for Davidson County's tornado warning. No other consumer device reliably performs that function at 1 a.m.
Tennessee's over 73 percent nighttime tornado fatality rate, the highest in the nation, reflects this pattern. Dixie Alley tornadoes are frequently rain-wrapped, fast-moving, and occur in every month. The single most important preparedness decision for a Tennessee household is ensuring that a tornado warning can wake every sleeping person.
Limits and methodology
What this page can and cannot tell you.
This page provides statewide and regional information to help Tennessee households make preparedness decisions. It cannot determine property-level risk. Flood zones, seismic exposure, wildfire interface status, slope stability, and utility vulnerability all require site-specific investigation.
Historical frequency is not a forecast. The fact that a hazard has not affected your area recently does not mean it will not. Maps and designations change as new data becomes available.
Official instructions during an active event always supersede general preparedness guidance. This page is for planning, not for during-event decision-making.
How hazards and regions were selected
Hazards were classified using the 2023 Tennessee State Hazard Mitigation Plan (FEMA-approved October 2023, effective through October 2028), FEMA disaster declaration history, NOAA Storm Events Database, USGS seismic hazard assessments, and NWS forecast office publications. Operational regions were defined by shared hazard patterns and NWS coverage areas rather than political or land-suitability boundaries.

Common questions
Tennessee local risk, answered.
What are the most consequential hazards for Tennessee households?
Tornadoes (including nighttime tornadoes in the Dixie Alley corridor), river and flash flooding, severe thunderstorms with large hail, ice storms causing extended power outages, earthquakes from the New Madrid Seismic Zone affecting West Tennessee, wildfire in the East Tennessee mountains, and extreme heat. Which hazards matter most depends on where in Tennessee you live. Middle Tennessee has the highest tornado activity. West Tennessee sits on the New Madrid Seismic Zone. East Tennessee faces wildfire, flash flooding in mountain terrain, and ice storms on the Cumberland Plateau.
How do I find my NWS forecast office and county emergency management in Tennessee?
Tennessee is served by three in-state NWS offices (Nashville, Memphis, and Morristown) plus two out-of-state offices that cover border counties (Huntsville, Alabama, covering Franklin, Lincoln, and Moore counties; and Paducah, Kentucky, providing NOAA Weather Radio coverage to parts of northwest Tennessee). Enter your address at weather.gov to find your local office. For county emergency management, contact the Tennessee Emergency Management Agency (TEMA) or check the TEMA website. Enroll in your county alert notification system for location-specific warnings.
Why are nighttime tornadoes especially dangerous in Tennessee?
Tennessee leads the nation in the proportion of tornado fatalities that occur at night, with over 73 percent of tornado deaths happening after dark. Tennessee sits in Dixie Alley, where tornadoes are frequently rain-wrapped, fast-moving, and occur in every month of the year. At night, people are asleep, phones may be silenced, and outdoor sirens are not designed to wake people inside sealed homes. A NOAA weather radio set to alarm mode on the nightstand is the single most important piece of preparedness equipment for Tennessee households.
What causes the longest power outages in Tennessee?
Ice storms cause the longest outages. The January 2026 winter storm (Winter Storm Fern) hit 29 counties and triggered a federal major disaster declaration. East Tennessee and the Cumberland Plateau are the most ice-prone areas. Ice accumulation brings down trees and utility lines, and rural areas with lines running through timber can lose power for days to weeks. Backup heat and stored water that do not depend on grid power are standard requirements for Tennessee households, especially in the eastern half of the state.
What should every Tennessee household do first to prepare?
Identify your NWS forecast office and enroll in your county alert system. Get a NOAA weather radio with alarm mode for nighttime tornado warning. Choose and practice a tornado shelter plan for every household member at every location. Check whether your home and regular travel routes cross a mapped flood hazard area. Store at least three days of drinking water. Establish a backup lighting and charging method. If you heat with electricity only, identify and test a backup heat source before winter. Keep a current medication list and copies of critical documents in a portable location.
