Hurricanes risk in Wisconsin

Hurricane risk in Wisconsin: what homeowners should know

Wisconsin is a landlocked state in the upper Midwest, hundreds of miles from the Atlantic Ocean and the Gulf of Mexico. Because hurricanes derive their energy from warm ocean waters, the state does not experience direct hurricane landfalls. In fact, the National Hurricane Center (NHC) notes that tropical systems typically weaken rapidly after moving inland, transitioning to tropical storms, depressions, or post-tropical cyclones. By the time any remnants reach Wisconsin, they are usually much weaker.

However, that does not mean Wisconsin is entirely immune to hurricane-related hazards. On rare occasions, the remnants of a hurricane or tropical storm can track into the Midwest, bringing heavy rainfall, flash flooding, and gusty winds. These events are infrequent, and the state's overall hurricane risk is rated 1 out of 5 by HomeRiskMap, indicating a very low likelihood of significant hurricane impacts.

The hurricane season officially runs from June 1 to November 30, but in Wisconsin, any remnant impacts typically occur later in the season, from August through October, when storms are more likely to curve northward. There is no specific region of the state that is more exposed than others; the entire state can receive heavy rain from a decaying tropical system. However, low-lying areas near rivers and streams, as well as communities with poor drainage, are more susceptible to flooding when these remnants pass through.

It's also worth noting that while direct hurricane conditions (sustained winds of 74 mph or higher) are extremely unlikely, the NHC may still issue advisories for tropical storms or depressions that affect the region. Wisconsin Emergency Management (WEM) monitors these situations and coordinates with local officials to keep residents informed. Homeowners should pay attention to forecasts from the National Weather Service and be prepared for heavy rain and potential flooding.

How it affects homes

Because direct hurricane impacts are so rare in Wisconsin, the primary concern for homeowners is not catastrophic wind damage but rather water. The remnants of a hurricane or tropical storm can produce several inches of rain in a short period, leading to flash flooding, river flooding, and basement flooding. This can result in costly water damage to foundations, basements, and personal belongings. In some cases, prolonged rainfall can also cause sewer backups, which may require professional cleanup and can pose health risks.

Wind damage is possible but typically limited to downed trees and power lines, which can cause roof damage, broken windows, and extended power outages. Since the ground may already be saturated from prior rain, even moderate winds can topple trees more easily. However, widespread structural damage from hurricane-force winds is not a significant threat in Wisconsin.

From an insurance perspective, standard homeowners policies generally cover wind damage, including damage from fallen trees (though you may need to pay a deductible). Flood damage, on the other hand, is almost never covered by a standard homeowners policy. To protect against flooding, you would need a separate flood insurance policy, typically through the National Flood Insurance Program (NFIP) or a private insurer. Many homeowners in Wisconsin may not have flood insurance because they don't live in a high-risk flood zone, but it's important to remember that flooding can happen anywhere, especially from heavy rainfall associated with tropical remnants. Also, be aware that some policies have a separate hurricane deductible, but these usually apply only when a hurricane watch or warning is issued by the NHC for your area. Since Wisconsin is far inland, such watches or warnings are rarely, if ever, issued, so the standard deductible typically applies.

How to prepare your home

Even though the risk is low, taking a few preparedness steps can help protect your home and family from the heavy rain and winds that can accompany tropical remnants. The following measures are recommended by Ready.gov, FEMA, and Wisconsin Emergency Management.

• Clear gutters and downspouts: Remove leaves and debris so rainwater can flow away from your foundation. Consider extending downspouts at least 5–10 feet from the house.
• Check your sump pump: Ensure it works properly and consider installing a battery backup in case of power outages.
• Seal cracks in your foundation and basement walls: This helps prevent water from seeping in during heavy rain. Also, consider applying waterproof sealant.
• Elevate utilities: If your furnace, water heater, or electrical panel is in the basement, consider raising them above potential flood levels. This can be a more involved project, but it can save thousands in repair costs.
• Trim trees and shrubs: Remove dead branches and limbs that could fall on your home during gusty winds. Keep trees well-maintained to reduce the risk of uprooting in saturated soil.
• Secure outdoor items: Bring in or tie down patio furniture, grills, and other loose objects that could become projectiles in high winds.
• Install a flood detection system or water alarm: These can alert you to water in your basement before it causes major damage.
• Review your insurance coverage: Talk to your agent about whether you need flood insurance. Remember that there is typically a 30-day waiting period for new flood policies.
• Create an emergency kit: Include water, non-perishable food, flashlights, batteries, a first-aid kit, and important documents. Ready.gov has a full list.
• Stay informed: Follow local weather forecasts and sign up for alerts from Wisconsin Emergency Management or your county emergency management agency.

Frequently asked questions

Can a hurricane hit Wisconsin directly?

No. A hurricane needs warm ocean water to sustain its strength, and Wisconsin is too far inland. By the time any tropical system reaches the state, it has weakened to a tropical storm, tropical depression, or post-tropical cyclone. Direct hurricane conditions—sustained winds of 74 mph or higher—have never been recorded in Wisconsin.

How often does Wisconsin experience hurricane remnants?

Remnants of tropical systems reach Wisconsin only occasionally—typically every few years. The National Hurricane Center tracks these systems, and when they are forecast to affect the Midwest, the National Weather Service issues local advisories. The impacts are usually limited to heavy rain and minor wind damage, but flooding can occur.

Does homeowners insurance cover hurricane damage in Wisconsin?

Standard homeowners insurance typically covers wind damage, such as from fallen trees or flying debris. However, flood damage is not covered by standard policies; you would need separate flood insurance. Since hurricane watches and warnings are rarely issued in Wisconsin, special hurricane deductibles are unlikely to apply. Always check your policy and consider flood insurance for comprehensive protection.
