Hurricanes risk in Minnesota

Hurricane Characteristics in Minnesota

Minnesota sits more than 1,000 miles from the nearest coast, so the state will never experience a direct hurricane landfall. The National Hurricane Center tracks tropical cyclones in the Atlantic basin, but by the time a system moves this far inland, it has typically lost its tropical structure and becomes an extratropical low-pressure system. However, the NOAA National Hurricane Center notes that remnants of hurricanes or tropical storms can occasionally push into the Upper Midwest, bringing intense rainfall and elevated severe weather risks.

In Minnesota, the primary threat from these remnant systems is heavy rain and flooding. Warm, moist tropical air can interact with local weather fronts, causing training thunderstorms that drop several inches of rain in a short period. Rivers and streams, especially those in the Minnesota River and Red River basins, can rise quickly and flood nearby homes. Additionally, these systems can increase the risk of tornadoes and damaging straight-line winds across the southern and central parts of the state.

The most likely time for tropical moisture to reach Minnesota is late summer and early fall, typically from August through October, when Atlantic hurricane activity peaks. Even though the frequency is low, the National Weather Service and state emergency managers monitor forecast tracks and alert residents to inland flood risks. Because these events are rare, many homeowners are caught off guard by the flooding they can cause, which often occurs far from any coastline.

How It Affects Homes

When the remnants of a tropical system affect Minnesota, the main impact on homes is water damage. Heavy rainfall can overwhelm street drains, infiltrate basements through cracks or window wells, and cause sewage backups. Homes located in floodplains or near rivers face the highest risk of structural flooding. In contrast, wind damage in Minnesota is usually less severe than in coastal states, though tornadoes embedded in these systems can remove roofs or topple trees onto houses.

Insurance considerations are vital for Minnesota homeowners. Standard homeowners insurance policies typically cover wind damage, but they do not cover flood damage. For that, you need a separate flood insurance policy through the National Flood Insurance Program, which is administered by FEMA. According to FEMA's hurricane preparedness guidance, flooding is the most common and costly hazard associated with these storms, even inland. Since Minnesota is rated low for hurricane risk, some homeowners skip flood insurance, but remember that heavy rain from any storm can cause flooding – a risk that exists regardless of hurricane landfalls.

If your home is near a lake, river, or low-lying area, consider a flood insurance quote even if you are not in a designated flood zone. Also, review your policy to see if it includes coverage for backup sewer and drain water, which is sometimes sold as an endorsement. The Minnesota Department of Commerce offers consumer guides on flood insurance, but you can also visit Ready.gov for national guidance on what to check in your policy.

How to Prepare Your Home

Even though hurricane risk is low, being prepared for the flooding and storms they can bring is smart for every Minnesota homeowner. Use the following steps to reduce potential damage:

• Clear your gutters and downspouts so rainwater flows away from your foundation. Extend downspouts at least 5 feet from the house.
• Install a sump pump with a battery backup to handle basement water intrusion during heavy rains.
• Check your yard grading – the ground should slope away from your home’s foundation to prevent pooling.
• Seal cracks in your basement walls and floor with hydraulic cement or waterproofing compounds.
• Secure loose outdoor items like patio furniture, grills, and planters that could become projectiles in high winds.
• Trim trees and remove dead branches near your home to reduce the risk of limbs falling during storms.
• Install window well covers to keep rainwater out of below-grade windows.
• Create an emergency kit with water, non-perishable food, medications, flashlights, and a weather radio. See Ready.gov for a full checklist.
• Know your flood risk by checking FEMA’s flood maps online, and consider buying flood insurance if you are in a vulnerable area.
• Make a family communication plan so everyone knows where to go if a flood or tornado warning is issued.

These steps are easy to implement and will also help with the severe summer thunderstorms that are common in Minnesota. Preparedness for tropical remnants is essentially the same as preparedness for any severe weather event.

Frequently Asked Questions

Can hurricanes actually hit Minnesota?

No. Minnesota is landlocked and far from any ocean, so a hurricane cannot make landfall in the state. However, the remnants of tropical systems can travel north and bring heavy rain, flooding, and tornadoes to Minnesota. These events are rare but possible, usually in late summer or early fall.

What kind of damage can tropical remnants cause in Minnesota?

The biggest threat is inland flooding from prolonged heavy rain. Basements can flood, roads can be washed out, and rivers can overflow. Some storms may also generate tornadoes or straight-line winds that cause roof damage and downed trees. Wind damage is usually less severe than on the coast, but flooding can be just as damaging, especially because many homeowners lack flood insurance.

Do I need flood insurance in Minnesota if the hurricane risk is low?

Flood insurance is worth considering because flooding can happen from any storm, not just hurricanes. Standard homeowners policies do not cover flood damage. About 25% of flood insurance claims come from areas outside designated high-risk flood zones, so even a low hurricane risk doesn’t eliminate the possibility of flooding. Check FEMA’s flood maps and talk to your insurance agent about your property’s specific risk.
