Hurricanes risk in Missouri

Hurricane Risk in Missouri: An Overview

Missouri is a landlocked state in the Midwest, far from the Atlantic Ocean and Gulf of Mexico. Because of this, the direct impact of a hurricane—a storm making landfall on Missouri's coast—is impossible. However, the remnants of hurricanes and tropical storms can still reach Missouri, typically after making landfall along the Gulf Coast and tracking northward up the Mississippi River Valley. The National Hurricane Center (NHC) notes that these decaying systems can still produce heavy rainfall, inland flooding, strong winds, and even tornadoes.

The hurricane season in the Atlantic runs from June 1 to November 30, but Missouri's risk from tropical remnants is highest from August through October, when the Gulf is warmest and storm tracks are more likely to curve inland. While any part of Missouri could see effects, the southeastern portion of the state—especially along the Mississippi River and its tributaries—is most vulnerable to flooding from tropical downpours. Low-lying areas, river valleys, and communities with poor drainage are at greatest risk. The Missouri State Emergency Management Agency (SEMA) works with local partners to monitor these threats and coordinate response.

Because of its inland location, Missouri's overall hurricane risk is rated very low—a 1 out of 5 on our scale. That does not mean zero risk. Historic examples show that remnant tropical systems can cause significant flooding and damage, even far from the coast. Being prepared is still wise.

How It Affects Homes

When remnants of a hurricane reach Missouri, the primary threat to homes is water, not wind. Torrential rainfall can overwhelm creeks, streams, and storm drains, leading to flash flooding and river flooding. Basements and crawl spaces are often the first to flood, causing foundation damage, mold growth, and ruined belongings. In some cases, floodwaters can enter ground floors, requiring extensive repairs.

Strong winds from remnant storms—or the severe thunderstorms and tornadoes they can spawn—can also damage homes. Downed trees and power lines may crush roofs, break windows, and cause power outages that last for days. Wind-driven rain can infiltrate roofs, siding, and windows, leading to water damage inside walls.

Insurance considerations are critical. Standard homeowners insurance policies typically cover wind damage and damage from fallen trees, but they do not cover flood damage. Flood insurance must be purchased separately, usually through the National Flood Insurance Program (NFIP) or a private insurer. Even if you don't live in a designated high-risk flood zone, consider buying flood insurance—flooding can happen anywhere. Review your policy to understand your deductible and whether you have separate wind/hail deductibles. The Missouri Department of Insurance offers guidance for consumers.

How to Prepare Your Home

While Missouri's hurricane risk is low, preparing for the associated flooding and severe weather is smart. Here are concrete steps you can take:

• Know your flood risk. Check FEMA flood maps and local emergency management resources to see if your home is in a flood-prone area. The Missouri SEMA website has links to preparedness information.
• Purchase flood insurance. There is typically a 30-day waiting period before a new flood policy takes effect. Don't wait until a storm is forecast.
• Maintain your drainage. Clear gutters and downspouts regularly. Make sure water flows at least 5–10 feet away from your foundation.
• Install a sump pump with battery backup. If you have a basement, a sump pump can remove water that accumulates. Battery backup ensures it works during power outages.
• Seal cracks in your foundation and basement walls. Use hydraulic cement or polyurethane sealant to keep water out.
• Elevate utilities. If your basement is prone to flooding, consider raising electrical panels, water heaters, and HVAC equipment onto platforms.
• Secure outdoor items. Bring patio furniture, grills, and trash cans inside, or anchor them. These can become projectiles in high winds.
• Trim trees and remove dead branches. This reduces the risk of limbs falling on your home or power lines.
• Reinforce your roof and windows. Check that shingles are secure. Consider impact-resistant windows or shutters if you live in an area prone to severe storms.
• Document your belongings. Take photos or videos of your home and possessions for insurance claims. Store copies in the cloud or a safe place.
• Create an emergency kit and plan. Include water, non-perishable food, medications, flashlights, and a battery-powered radio. Know your evacuation routes and stay informed via local news and NOAA Weather Radio.

Frequently Asked Questions

Can a hurricane directly hit Missouri?

No. Missouri is landlocked, so a hurricane cannot make landfall there. However, the remnants of a hurricane or tropical storm can move into Missouri, bringing heavy rain, flooding, and severe weather. These remnant systems can still be dangerous, especially if they stall and produce prolonged rainfall.

Does homeowners insurance cover hurricane damage in Missouri?

It depends on the type of damage. Most homeowners policies cover wind damage from hurricanes or tropical storms, as well as damage from falling trees. However, flood damage is almost never covered by standard policies; you need a separate flood insurance policy. Review your policy carefully and talk to your insurance agent about your specific risks.

When is hurricane season in Missouri?

While Missouri doesn't have a "hurricane season" in the traditional sense, the Atlantic hurricane season runs from June 1 to November 30. The risk of remnant storms affecting Missouri is highest from August through October. However, tropical systems can form earlier or later, so it's wise to stay prepared throughout the season.
