Severe Storms risk in Alaska
Minor — level 2 of 5

Alaska's severe storms are a level 2 out of 5 risk statewide, but that still means high winds, hail, and lightning can damage your home. Know what your insurance covers and how to prep before the season starts.

You're two weeks from closing on a house in Palmer when the seller mentions the roof was replaced after a hailstorm last July. That's a clue: severe storms in Alaska aren't just coastal. They happen in the Interior, the Mat-Su Valley, and Southeast. The statewide risk is a 2 out of 5, which sounds mild until you realize 'mild' here means 60 mph winds that peel back shingles, lightning that starts wildfires, and hail that dents siding.
This page is for homeowners and buyers who want the straight story on what storms do to a house in Alaska, what insurance actually pays for, and what to do first.
Who this hits hardest
Storms don't hit every part of Alaska the same way. The Interior — Fairbanks, North Pole, the Tanana Valley — gets the most thunderstorms. Warm summer days build up cells that drop lightning and small hail. That lightning is a big deal because it can start fires in the boreal forest, and a wildfire doesn't care about your property line.
Southcentral Alaska, including Anchorage, the Matanuska-Susitna Borough, and the Kenai Peninsula, sees strong winds. These often come with fall storms or 'Chinook' events that can gust hard enough to take down trees and power lines. If your house sits at the edge of a subdivision with mature spruce or birch, you're more exposed. So are homes on ridgelines or near open water.
Southeast Alaska — Juneau, Ketchikan, Sitka, Petersburg, Wrangell — gets plenty of rain and wind. The wind can drive water into places it doesn't belong, which is a flood problem. And the Aleutians and Kodiak? They're in the path of some of the most powerful extratropical cyclones on the planet.
Who gets hit hardest? Generally, older homes with original roofs, mobile homes, and any house surrounded by tall trees. Also, anyone who assumes their standard policy covers everything. It doesn't. We'll get to that.
After the event — claims and repairs
After a storm rolls through, the first 48 hours matter. If it's safe, take photos and video of everything — the roof, the siding, the downed tree on your fence, the water in your basement. Your insurance adjuster will want them. Don't throw away damaged items until you've documented them.
Then call your insurer. Here's the reality: your standard homeowners policy usually covers wind and hail damage to the structure. That includes roof repairs, broken windows, and maybe tree removal if the tree hit the house. But it typically does not cover flood damage. Flood means water that comes from the ground up or from a storm surge. If a storm dumps three inches of rain and your crawlspace floods, that's a flood claim — and you need a separate NFIP policy or private flood insurance. In Alaska, that's a gap many people discover too late.
Earthquake damage? Also excluded. Alaska is earthquake country. If a quake shakes loose your chimney during a storm, your standard policy won't help unless you bought a separate endorsement.
Another thing: wind vs. flood can be a fight. If wind blows off your roof and then rain pours in, the insurer may say the damage is from rain (flood) not wind. That's why documentation and a good public adjuster can matter. But start with your own photos.
Repairs: After a big storm, contractors flood the area. Get at least three bids. Never pay the full amount upfront. Ask for a local license and proof of insurance. The Alaska Division of Homeland Security & Emergency Management has post-disaster tips on its site, but the main thing is to not rush into a bad contract.
Before the season starts
You don't need a bunker. You need a weekend and a few hundred dollars. If I had to pick one thing, I'd start with your roof and the trees closest to your house. Loose shingles and overhanging dead branches are the two most common causes of storm damage I see.
Here's a practical list:
- Walk your roof (or hire someone) and replace missing or lifted shingles. Check flashing around chimneys and vents.
- Trim dead branches within 10 feet of your house. If a tree is dead and leaning toward your bedroom, pay to remove it.
- Clean gutters and downspouts. Water that can't drain away finds your foundation.
- Check your sump pump if you have one. Test it with a bucket of water.
- Secure or store outdoor furniture, grills, and trampolines. Those become projectiles in high wind.
- Build a basic emergency kit: water, non-perishable food, flashlights, batteries, a battery-powered radio, and a first-aid kit. Ready.gov has a full list.
- Know your insurance deductible for wind and hail. Some policies have a separate, higher deductible for those perils. Call your agent and ask.
Also, consider flood insurance even if you're not in a mapped flood zone. In Alaska, heavy rain and rapid snowmelt can cause flooding anywhere. NFIP policies typically have a 30-day waiting period, so don't wait for the forecast to look ugly.
Questions we get
Does my homeowners insurance cover storm damage in Alaska?
Usually yes for wind, hail, and lightning damage to the structure. But flooding — from rain, snowmelt, or storm surge — is excluded. You need a separate flood policy. Earthquake damage is also excluded. Read your policy or ask your agent for the exclusions page.
What's the difference between a wind claim and a flood claim in Alaska?
Wind claim: your roof shingles blow off, a tree hits your deck, or hail cracks your siding. Flood claim: water enters your home from outside, whether from a rising river, poor drainage, or a storm surge. Insurers treat them differently, and they often disagree about which caused the damage. Take photos before you clean up.
Should I buy flood insurance if I live in Anchorage or Fairbanks?
Anchorage and Fairbanks both have flood-prone areas, even if you're not near a river. FEMA flood maps show risk zones, but heavy rain can overwhelm storm drains anywhere. If you have a basement or crawlspace, it's worth a quote. NFIP policies are available through most agents.

One more thing: don't rely on a single source. Check the National Risk Index for your borough or census area, and talk to a local insurance agent who knows Alaska. The risk is a 2 out of 5 statewide, but your specific spot on the map could be higher or lower.
Common questions
- How serious is severe storms in Alaska?
- Alaska is rated Minor (2 of 5) for severe storms at the state scale. That is a starting point — two addresses in the same county can differ.
- Does insurance cover severe storms here?
- Hail and wind are common claim types. Keep a dated photo of the roof. Flooding from the same thunderstorm is a different policy.
