Hurricane Risk in Vermont: What to Expect

Vermont is an inland state located in the Northeast, far from the Atlantic coast where hurricanes typically make landfall. As a result, a direct hurricane strike is extremely unlikely—the state's overall risk level is rated 1 out of 5 by FEMA's National Risk Index. However, Vermont is not completely immune to the effects of hurricanes. When tropical systems move northward after hitting the U.S. coast, they often weaken into tropical storms or post-tropical cyclones before reaching New England. Even when downgraded, these systems can bring several inches of rain, strong winds, and the potential for flooding.

The typical season for any tropical influence runs from June 1 to November 30, with the greatest odds in August and September. Vermont's geography—characterized by steep slopes, valleys, and numerous rivers—can amplify flooding risks. Low-lying areas along major rivers such as the Winooski, Lamoille, and Otter Creek, as well as mountainous regions with poor drainage, are most exposed to flash flooding and river flooding. According to the Vermont Emergency Management, the primary threat from tropical remnants is widespread heavy rain rather than hurricane-force winds.

How It Affects Homes

Because Vermont's hurricane risk is so low, most homes are not built to withstand hurricane-force winds, but they are generally well-adapted to the region's typical weather. The main concern for homes during a tropical remnant event is water damage. Excessive rainfall can overwhelm drainage systems, cause basement flooding, or lead to sewer backups. In rural areas, driveways and access roads can wash out, isolating homes.

Wind damage is rare but possible—especially if thunderstorms embedded in a storm system produce gusty winds. Saturated ground from heavy rain can also cause trees to topple onto roofs, sheds, or power lines, resulting in structural damage and power outages that may last for days.

When it comes to insurance, standard homeowners policies generally do not cover flooding. To protect against flood damage, residents may need to purchase a separate flood insurance policy through the National Flood Insurance Program (NFIP), which is administered by FEMA. As noted on FEMA's Hurricane Preparedness page, flood insurance is available to homeowners, renters, and businesses even in moderate-to-low-risk areas. Even if your home is not in a designated flood zone, it is worth discussing your options with an insurance agent.

How to Prepare Your Home

Preparation can make a big difference when heavy rain threatens Vermont. Here are concrete steps you can take, drawing from Ready.gov and other official guidance:

• Clear rain gutters, downspouts, and drains of leaves and debris so water can flow away from your roof and foundation.
• Test your sump pump before each rain season and consider adding a battery backup in case of power loss.
• Install check valves in plumbing to prevent sewer backup into your home.
• Move valuable items, electronics, and important documents off the basement floor or to higher shelves.
• Seal cracks in your foundation and around windows and doors with weatherproof sealant.
• If you live in a flood-prone area, consider stacking sandbags or installing a temporary flood barrier around doorways.
• Create a family emergency plan, including where to go if a flood warning requires you to evacuate.
• Assemble an emergency kit with water, non-perishable food, flashlights, batteries, cash, and medication for at least three days.
• Listen to local alerts and sign up for Vermont Alert, the state's emergency notification system, through Vermont Emergency Management.

Frequently Asked Questions

How often do hurricanes actually affect Vermont?

Hurricane remnants pass over or near Vermont about once every few years, but significant flooding events are less common. The most notable recent example occurred in 2011 when Tropical Storm Irene, the remnants of Hurricane Irene, caused catastrophic flooding in Vermont. Since then, the state has improved its preparedness, but the return interval for similar events is uncertain.

What is the main danger from hurricanes in Vermont?

The main danger is not high winds but the heavy rainfall that can lead to flash flooding, river flooding, and landslides. Soils in Vermont are often shallow and quickly become saturated, increasing runoff. Low-lying roads and basements are the most vulnerable.

Do I need flood insurance in Vermont?

Flood insurance is not legally required unless you have a federally backed mortgage and live in a designated Special Flood Hazard Area. However, flooding can happen in low-risk areas, and standard homeowners insurance excludes flood damage. Given Vermont's history of inland flooding from storm remnants, purchasing a low-cost flood insurance policy is a wise investment for many homeowners.
