Primary hazards. Ranked.
Mississippi averages 27 tornadoes per year — one of the highest rates in the Southeast. Dixie Alley tornadoes often strike at night and move faster than Plains tornadoes. The 2011 Super Outbreak hit Mississippi hard; the 2023 Rolling Fork EF-4 killed 21 people in a matter of minutes. The Gulf Coast is direct hurricane exposure. Hurricane Katrina (2005) made landfall near Bay St. Louis and devastated the entire Mississippi coast — storm surge reached 28 feet in some areas. The coast has been rebuilt but remains among the most surge-vulnerable in the country. The Mississippi Delta floods chronically — the Yazoo Backwater area has been under flood conditions for months at a time in recent years. Jackson's Pearl River overtops regularly. Flooding is the most frequently recurring disaster in the state.

Insurance gaps
What your homeowner's policy doesn't cover.
Standard homeowner's policies in Mississippi exclude flood damage. Flood insurance through the NFIP has a 30-day waiting period — it cannot be purchased when a storm is forecast. Check your declarations page annually to confirm your coverage limits and deductibles.
Not in your standard policy
Flood damage — requires NFIP or private flood policy
Earthquake damage — requires separate endorsement
Sewer & drain backup — requires endorsement ($50–$100/yr)
Landslide / mudflow — generally excluded
