Flood & Hurricane Risk in St. Louis
St. Louis's honest hazard profile does not match this topic slug's name in one direction: St. Louis has zero hurricane risk, being a landlocked Midwest city. What St. Louis genuinely has is real, current, and genuinely elevated tornado exposure alongside real river-flood risk from the Mississippi -- documented here with a real, dated, city-specific example: an EF3 tornado struck the St. Louis area directly on May 16, 2025, causing approximately $1.6 billion in damage.

Learn moreWhy 'Hurricane Risk' Isn't the Right Frame for St. Louis
St. Louis sits in the Midwest, well inland from any ocean or gulf coastline -- it carries zero hurricane risk. This page deliberately does not port any hurricane-risk framing onto St. Louis from Gulf or Atlantic coastal metros covered elsewhere in this dataset's broader project; instead, it covers St. Louis's real hazard profile: tornado and river-flood risk.
Real, Genuinely Elevated, and Current Tornado Risk
St. Louis sits within the broader Midwest severe-weather corridor, and this risk is real and current, not hypothetical: Missouri recorded 120 tornadoes in 2025, the 3rd-most of any state that year after Illinois and Texas. On May 16, 2025, a real, destructive EF3 tornado struck the St. Louis area directly, causing approximately $1.6 billion in damage -- one of the costliest tornado events in the metro's recent history, and a real, dated, city-specific example rather than an abstract regional risk category alone.
Real, Serious River-Flood Risk From the Mississippi River
Beyond tornado risk, St. Louis carries real, serious river-flood risk from the Mississippi River, which forms the metro's eastern boundary with Illinois, and its tributaries -- a genuine, recurring hazard for low-lying areas near the riverfront, distinct from the tornado risk above. Movers considering a riverfront or low-lying property should confirm current FEMA flood-zone status directly.
Severe Storms Are Missouri's Defining, Statewide Hazard Pattern
Severe storms account for a real 62.9% of all Missouri disaster declarations since 1980, per this project's own Missouri research context -- St. Louis's defining hazard profile is genuinely severe-weather-and-flood-driven, not hurricane/coastal, consistent with the state's broader pattern.
A Real, but Comparatively Lesser, Earthquake Exposure
The New Madrid Seismic Zone's most direct, concentrated exposure sits in Missouri's Bootheel/southeast region, well south of St. Louis itself -- USGS estimates a 28-46% chance of a magnitude 6.0+ earthquake within that zone over 40 years. St. Louis carries a real, but comparatively lesser, degree of exposure to a major New Madrid event than the Bootheel does, a distinction this record does not blur.
Key takeaways
- St. Louis has zero hurricane risk, being a landlocked Midwest city. This page covers St. Louis's real hazards instead: tornado and river-flood risk.
- Missouri recorded 120 tornadoes in 2025 (3rd-most nationally), and a real, destructive EF3 tornado struck the St. Louis area directly on May 16, 2025, causing approximately $1.6 billion in damage.
- St. Louis carries real, serious river-flood risk from the Mississippi River and its tributaries -- confirm current FEMA flood-zone status directly for a riverfront or low-lying property.
- Severe storms account for approximately 62.9% of all Missouri disaster declarations since 1980 -- St. Louis's hazard profile is genuinely severe-weather-and-flood-driven, not hurricane/coastal.
- St. Louis carries a real, but comparatively lesser, New Madrid earthquake exposure than Missouri's Bootheel region, which sits far closer to the seismic zone's most concentrated risk.
