Hurricanes risk in Iowa

Hurricane risk in Iowa: Geography and reality

Iowa’s location in the American Midwest places it far from both the Gulf of Mexico and the Atlantic Ocean. As a result, the state does not experience direct hurricane landfalls. The National Oceanic and Atmospheric Administration (NOAA) tracks tropical storms and hurricanes every year, but by the time these systems move inland, they have usually weakened significantly. In Iowa, the risk of hurricane-force winds is extremely low, and the state is rated level 1 out of 5 for hurricane risk by FEMA's National Risk Index.

The hurricane season officially runs from June 1 through November 30. During this period, remnants of tropical cyclones can move into the Midwest, bringing heavy rainfall and, in some cases, severe flooding. Eastern and southern Iowa are more likely to see these remnants, especially when storm tracks push moisture northward. While tornadoes and straight-line thunderstorms are more common threats, it is still important for Iowans to understand what hurricane remnants can do.

Unlike coastal states, Iowa does not face storm surge, saltwater intrusion, or category-level winds. Instead, the primary concern is rainfall. A slow-moving tropical remnant can produce several inches of rain in a short time, causing rivers, creeks, and streams to overflow. Low-lying areas near the Mississippi and Missouri rivers are particularly vulnerable to flooding from such events.

How it affects homes

For Iowa homeowners, hurricane-related damage typically comes from flooding rather than wind. Heavy rains from tropical remnants can overwhelm storm drains and cause basement flooding. Water can seep through foundations, damage drywall, ruin personal belongings, and create conditions for mold growth. In severe cases, flash flooding can undermine a home’s structure or make roads impassable.

Wind damage from a tropical system is rare in Iowa, but when storms pass through, they can still produce gusts strong enough to damage roofs, windows, and outbuildings. However, these gusts are usually no stronger than those from a typical severe summer thunderstorm.

Insurance is a critical consideration. Standard homeowners insurance policies generally cover wind damage, but they do not cover flood damage. For that, you need a separate flood insurance policy, often through the National Flood Insurance Program (NFIP). Even if you are not in a high-risk flood zone, flooding can happen anywhere, and it is worth checking with your insurance agent to confirm your coverage. The Iowa Homeland Security and Emergency Management office advises residents to review their policies before a storm threatens.

How to prepare your home

• Check your flood risk. Visit FEMA’s Flood Map Service Center or your local county emergency management office to see if your property is in a floodplain.
• Consider flood insurance. Even if you are not required to carry it, flood insurance can save you financially after a flood event. Remember there is typically a 30-day waiting period before a new policy goes into effect.
• Clear gutters and downspouts. Make sure water can flow freely away from your foundation. Extend downspouts at least 5 feet from the house.
• Install a sump pump. If you have a basement, a battery-backed sump pump can help prevent water accumulation during heavy rains.
• Elevate valuables. Move furniture, electronics, and other important items off the basement or ground floor if flood warnings are issued.
• Create an emergency kit. Include water, non-perishable food, flashlights, batteries, medications, cash, and important documents in a waterproof container.
• Stay informed. Sign up for local weather alerts and listen to NOAA Weather Radio for updates on tropical systems that could affect your area.

Frequently asked questions

Can a hurricane really hit Iowa?

No, a fully developed hurricane cannot make landfall in Iowa because the state is hundreds of miles from any coast. However, the remnants of a hurricane can move into Iowa, bringing heavy rain, gusty winds, and flooding. These events are often called “inland tropical systems” and can still cause serious problems.

Does homeowners insurance cover hurricane damage?

Standard homeowners insurance generally covers wind damage but does not cover flood damage. Since the main threat in Iowa from tropical remnants is flooding, you would need a separate flood insurance policy to protect your home and belongings. Check with your insurance provider to understand your exact coverage.

What should I do if a tropical system is forecast for Iowa?

Monitor reliable sources like the NOAA National Hurricane Center and your local National Weather Service office. Follow instructions from local emergency management, and be ready to move to higher ground if flooding is forecast. Prepare your home by clearing drains, securing loose items, and having a plan for you and your family.
