Check it before you act on it.

Bad information moves faster than corrections. This page teaches one habit: before a claim changes your plans, find out where it came from and whether the source is official. That takes about 60 seconds.

The problem

Speed rewards the wrong things.

During a confusing moment, the information that moves fastest is rarely the information that matters most. A screenshot of a social media post travels through a group chat in seconds. The official update from the county emergency management office takes longer because someone has to confirm the facts, write the statement, and route it through the correct channels.

This is not a problem you can fix for the whole internet. It is a problem you can fix for your household. The fix is a habit: before a piece of information changes a decision, check where it came from. If it came from an official source, act on it. If it came from anywhere else, find the official source before acting.

The rest of this page teaches that habit for the situations where it matters most.

The short list

Official channels for a household.

You do not need to monitor dozens of sources. For most household decisions during a confusing moment, five channels cover it.

Your county emergency management office

The local authority for disaster declarations, evacuation orders, shelter openings, and emergency coordination. Find yours on your state page or search "[county name] emergency management." Follow their official social media account and sign up for their reverse-911 or alert system if available.

The National Weather Service

The source of all watches, warnings, and advisories for weather hazards. Your local NWS forecast office issues the alerts that matter for your area. Bookmark weather.gov and enter your location. A NOAA Weather Radio provides alerts even when the internet and cell service are down.

Wireless Emergency Alerts (WEA)

The loud alerts that push directly to cell phones in a targeted area without requiring any signup. WEA carries AMBER alerts, severe weather warnings, and presidential alerts. If your phone buzzed with a WEA, the alert is real. WEA depends on cell tower coverage; if towers are down, the alert may not reach you.

Your municipality or county website

Official .gov websites are the authoritative source for local orders, closures, and public notices. During an active event, many jurisdictions post updates to a dedicated emergency page. Bookmark your city or county website now, before you need it. A .gov domain means the site belongs to a government entity.

Your local newsroom

The local TV station, radio station, or newspaper that covers your county. Local newsrooms relay NWS alerts and county EM statements and provide context that national outlets cannot. They are not a primary source, but they are a useful amplifier of primary sources, and they often have a reporter at the county EOC during active events.

The distinction that matters most

Watch means prepare. Warning means act.

The National Weather Service uses three levels of severity for weather alerts. The distinction between a watch and a warning is the most important piece of weather literacy a household can have, and it is the one most often confused.

Advisory

Conditions may cause inconvenience but are not life-threatening if caution is used. Be aware. Adjust plans if needed.

Watch

Conditions are favorable for the hazard to develop. The event is possible, not certain. Prepare now so you can act fast if a warning follows. A tornado watch means conditions could produce a tornado; it does not mean one has formed.

Warning

The hazard is imminent or already occurring. Take action now. A tornado warning means a tornado has been spotted or detected on radar. Move to shelter immediately. Do not wait to verify the weather yourself.

Source: National Weather Service. The same advisory/watch/warning hierarchy applies to winter storms, floods, excessive heat, hurricanes, and other weather hazards. The specific thresholds vary by hazard type and by region.1

The habit

The 60-second verification check.

When a claim arrives that could change a household decision, run through these four questions before acting on it. Most of them take a few seconds each.

1

Where did this come from?

Trace the claim back to its origin. A screenshot shared in a group chat is not a source. A post from a verified government account is. A .gov URL is official. A .com URL may be a news site, a blog, or something else entirely. If the claim came through someone who forwarded it, find the original.

2

Does the official source say the same thing?

Go directly to the source that would issue this type of information. Weather claim: check weather.gov. Evacuation claim: check your county EM website or social media. Product recall: check cpsc.gov. If the official source does not mention it, the claim may be outdated, exaggerated, or fabricated.

3

When was this published?

Old information presented without a date is one of the most common sources of confusion during an active event. A screenshot from a previous storm gets reshared during the current one. An alert from Tuesday circulates on Thursday. Check the timestamp. If there is no date, treat it as unverified.

4

Does it want you to feel something, or do something?

Official emergency communications tell you what to do: evacuate this zone, boil your water, shelter now. They do not tell you to be afraid, angry, or outraged. If a message is designed to produce an emotion rather than an action, that is a signal to verify before sharing.

The one-line version: If it did not come from a .gov website, a verified government social media account, or the National Weather Service, verify it before you act on it or share it.

What trips people up

Four patterns that look real but are not.

The reshared screenshot

A screenshot of a weather map, an alert, or an official-looking statement shared in a text chain or on social media. Screenshots strip context, dates, and source links. They are easy to fabricate and impossible to verify in their shared form. Go to the original source instead.

The old alert presented as current

During active events, old alerts from previous years or previous storms circulate as though they are current. A flood warning from 2024 gets forwarded during a 2026 storm. Always check the date on any alert before acting.

The official-sounding account

Social media accounts can use names and logos that look like government agencies but are not. Look for the verification badge (where available), check the account's history and follower count, and cross-reference with the agency's actual website. CISA advises relying on official .gov websites rather than social media as the primary source during a confusing moment.2

The claim from a national source about your specific area

National news coverage often paints broad regions as affected when only specific counties or zones are under an order. "The Southeast is bracing for impact" does not mean your county is under a warning. Check your county's EM office for the specific zones and orders that apply to your address.

Enough for now

You have this habit when...

  • You know the difference between a watch and a warning and can explain it to someone in your household.
  • You have bookmarked weather.gov and your county EM office's website or alert page.
  • When a claim arrives through a group chat or social media, your first move is to check the original source before forwarding.
  • You check the date on any alert before acting on it.

This is a habit, not a one-time task. The habit gets easier every time you use it, and it spreads when your household sees you do it.

Keep going
