Tornado tops the risk list, and FEMA has declared Missouri a disaster area 85 times since 1953. Here's what to prepare for — and how.
Missouri sits at a crossroads of competing weather systems, making it one of the more hazard-prone states in the continental United States. Warm, moist air pushing north from the Gulf of Mexico collides with cold continental air masses across the Missouri and Mississippi river valleys, producing conditions favorable for severe thunderstorms, tornadoes, and catastrophic flooding. FEMA has issued 74 major disaster declarations for Missouri, with severe storms and flooding accounting for the overwhelming majority of incidents. Tornadoes pose a persistent threat: the Joplin tornado of May 2011 killed 161 people and caused more than $2.8 billion in damage, ranking among the deadliest single tornadoes in U.S. recorded history. Flooding is equally consequential — the Great Flood of 1993 inundated millions of acres along the Missouri and Mississippi rivers, displaced tens of thousands of residents, and caused widespread agricultural losses across the state. Earthquake risk, while less visible in daily life, is genuine; Missouri lies near the New Madrid Seismic Zone, which produced a series of powerful earthquakes in 1811 and 1812 that remain among the largest in North American history. Winter storms, including severe ice storms that have knocked out power to hundreds of thousands, add a fourth recurring threat. Taken together, this history means Missouri residents cannot prepare for a single hazard and call it done. A comprehensive household plan — covering shelter-in-place for tornadoes, evacuation routes for floods, and multi-day supply kits for winter outages — is the practical baseline every family should maintain.
Tornadoes can form within minutes and level a home — identify your safe room now.
Flooding is the most common US disaster — just 6 inches of moving water can knock a person down.
Earthquakes strike without warning — structural damage and broken water mains are common.
Extended winter storms knock out power for days — prepare to survive without heat.
This region faces intense tornado exposure, as demonstrated by the 2011 Joplin disaster, and is also susceptible to flash flooding in narrow Ozark stream valleys.
The Bootheel lies directly above the New Madrid Seismic Zone, making earthquake risk the highest in the state, while its low-lying terrain also makes it highly vulnerable to Mississippi River flooding.
Communities along the Missouri River corridor face recurring major flood events, with agricultural and residential areas repeatedly inundated during high-water years.
Northern Missouri's open terrain increases exposure to severe winter storms and ice storms that can isolate rural communities and collapse infrastructure for days.
The St. Louis region contends with significant flood risk at the confluence of the Missouri and Mississippi rivers, along with tornado tracks that regularly affect densely populated suburbs.

The state's official emergency management agency — alerts, shelter info, and disaster assistance.
Missouri residents can receive official emergency alerts through the Missouri Emergency Alert System and Wireless Emergency Alerts broadcast automatically to cell phones; residents should also check with their county emergency management office to register for any local notification systems.
What natural disasters is Missouri most at risk for?
Missouri faces high risk from tornadoes and flooding, both documented by dozens of major federal disaster declarations. Earthquake risk from the New Madrid Seismic Zone is moderate but significant, and severe winter ice storms regularly affect the entire state. Residents should maintain preparedness plans that address all four of these hazard types.
How can I receive emergency alerts in Missouri?
Missouri uses the Missouri Emergency Alert System alongside the nationwide Wireless Emergency Alerts, which push notifications to cell phones in affected areas without requiring sign-up. Residents are also encouraged to register with their county's local alert system, as many counties maintain separate notification platforms for localized events such as flash floods or hazmat incidents.
Is earthquake preparedness really necessary in Missouri?
Yes. Missouri sits adjacent to the New Madrid Seismic Zone, responsible for powerful earthquakes in 1811 and 1812 that were felt across much of eastern North America. Scientists consider the zone capable of producing significant future events. Residents should secure heavy furniture, keep emergency supplies on hand, and know how to Drop, Cover, and Hold On during shaking.
What should a basic Missouri household emergency kit include?
A Missouri household kit should cover at least 72 hours of self-sufficiency: water (one gallon per person per day), non-perishable food, a battery or hand-crank weather radio, flashlights, medications, copies of important documents, and a first-aid kit. Given Missouri's tornado risk, every household should also identify and be able to quickly reach an interior, lowest-floor shelter location.
