Hurricanes risk in Washington

Hurricane risk in Washington: what homeowners should know

Washington state has a Level 1 (very low) hurricane risk rating. Direct hits by hurricanes are virtually unheard of because the Pacific Ocean off the Washington coast is too cool to sustain tropical cyclones. However, the remnants of tropical storms or post-tropical cyclones can occasionally reach the Pacific Northwest, bringing heavy rain and strong winds. The state's primary windstorm threat comes from extratropical cyclones, not hurricanes.

Geography plays a key role. The most exposed areas are the outer coast (Pacific County, Grays Harbor, Clallam, Jefferson counties), the Olympic Peninsula, and low-lying parts of Puget Sound. The Cascade Mountains and the Coast Range act as barriers, weakening systems as they move inland. Hurricane season in the Eastern Pacific runs from May 15 to November 30, but any impacts in Washington would typically occur in late summer or autumn.

According to NOAA's National Hurricane Center, no hurricane has ever made landfall in Washington state. The cold California Current keeps sea surface temperatures well below the 26.5°C (80°F) threshold needed for tropical cyclone formation and maintenance. Occasionally, a tropical storm or hurricane from the eastern Pacific will move north and transition into an extratropical cyclone, but by the time it reaches Washington, it has lost its tropical characteristics. The famous Columbus Day Storm of 1962 was a remnant of Typhoon Freda, but it had become an extratropical cyclone before impacting the Pacific Northwest.

How it affects homes

Because direct hurricane impacts are so rare, most Washington homes will never experience hurricane-force winds. However, when remnants of tropical systems or strong extratropical cyclones do occur, the main risks are:

• Wind damage: Fallen trees and branches can crush roofs, break windows, and knock down power lines. Older homes with unreinforced roofs or siding may be more vulnerable.
• Flooding: Heavy rain can cause flash flooding, especially near rivers, streams, and urban areas with poor drainage. Storm surge is a minor concern compared to the Gulf or Atlantic coasts, but coastal flooding can happen during strong storms.
• Power outages: Downed lines can leave homes without electricity for days, affecting heating, refrigeration, and medical equipment.

Insurance considerations: Standard homeowners insurance policies in Washington typically cover wind damage from hurricanes and other storms, 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. Unlike some coastal states, Washington does not have a mandatory hurricane deductible, but it's wise to review your policy for any windstorm deductibles. Document your belongings and keep receipts. If your home is in a flood zone, your lender may require flood insurance.

How to prepare your home

Even though the risk is low, preparing for severe wind and rain is smart. The Washington Emergency Management Division recommends an all-hazards approach. Use these steps to reduce potential damage:

1. Trim trees and shrubs: Remove dead branches and limbs that could fall on your home or power lines. Keep trees at least 10 feet away from structures.
2. Secure or store loose outdoor items: Bring in patio furniture, grills, trash cans, and garden decorations before a storm.
3. Reinforce your roof: Check for loose shingles or tiles. Install hurricane straps or clips if you live in a high-wind area (though this is more common in hurricane-prone states, it can still help).
4. Clear gutters and downspouts: Prevent water from pooling on your roof or around your foundation.
5. Install storm shutters or impact-resistant windows: These can protect against flying debris. Alternatively, cut plywood panels in advance.
6. Check your sump pump and drainage: Ensure they work properly, and consider a battery backup.
7. Create an emergency kit: Include water, non-perishable food, flashlights, batteries, a first-aid kit, medications, and copies of important documents. Ready.gov has a full list.
8. Know your evacuation route: Plan how to leave if authorities issue an evacuation order.
9. Review your insurance: Understand what is covered and consider flood insurance if you are in a flood-prone area.
10. Stay informed: Sign up for local alerts through your county emergency management agency and monitor NOAA Weather Radio.

Frequently asked questions

Has Washington state ever been hit by a hurricane?

No. According to NOAA's National Hurricane Center, there has never been a recorded hurricane landfall in Washington state. The waters off the Pacific Northwest are too cold to support hurricanes. The strongest windstorms in the region's history, such as the 1962 Columbus Day Storm, were extratropical cyclones, not hurricanes.

What is the hurricane season in Washington?

Washington does not have a hurricane season because hurricanes do not form or typically track there. The Eastern Pacific hurricane season runs from May 15 to November 30, but any remnant moisture or energy that reaches Washington usually arrives as a weakened, non-tropical storm, most likely in September or October.

Do I need hurricane insurance in Washington?

Washington does not have a state-mandated hurricane insurance requirement. Your standard homeowners policy likely covers wind damage from any storm, including remnants of tropical systems. However, flood damage is excluded, so if you live in a flood-prone area, consider purchasing separate flood insurance through the NFIP. Check with your insurance agent to understand your specific coverage. For more federal guidance, see FEMA Hurricane Preparedness.
