May is Wildfire Awareness Month, a time focused on prevention, preparedness, and protecting what matters, together.

Wildfires are largely preventable, with nearly 85% caused by human activity. Taking steps to reduce risk, prepare your home and family, and stay informed all play an important role in keeping communities safe.

Tomorrow, May 2, is Wildfire Community Preparedness Day, remember that small actions can make a big difference. Take a few steps to reduce risk where you live:
• Clear dry vegetation and debris around your home
• Create and maintain defensible space
• Check local fire restrictions and conditions before outdoor activities
• Make a plan with your family in case of evacuation

Floodwaters move fast and can be deadly. Stay informed with NOAA Weather Radio or local alerts. If water is rising, get to higher ground. Never walk or drive through floodwaters—just 6 inches can knock you down.

A flood can cut off access to roads, power, or clean water. Be ready with an emergency kit that includes food, water, a NOAA Weather Radio, first aid supplies, medications, and important documents in a waterproof container.

🧊 Ice jams are a major cause of spring flooding in Alaska. They form quickly, block rivers, and send water into nearby communities.

River breakup isn’t the same every year. Snowpack, ice thickness, and spring temperatures all play a role and small changes can impact flood risk.

Spring in Alaska means ice breakup, rising rivers, and melting snow. Ice jams and snowmelt are the biggest spring flooding threats. Know your risk and prepare before the water rises.

As Alaska rivers break up each spring, flooding risks can increase quickly. River Watch helps monitor ice conditions and provide real-time information to communities.

Learn how it works and why it matters.

🌊Today in Tsunami History 🌊
March 27, 1964: the Great Alaska Earthquake triggered tsunamis that caused widespread damage, including in Kodiak.

It’s a reminder that Alaska has experienced powerful tsunamis before.

❌ MYTH: Tsunamis only happen in the Pacific.
✅ FACT: All US coasts are susceptible, including the Atlantic & Gulf.
❌ MYTH: Tsunamis are just one wave.
✅ FACT: They come in multiple waves over hours. The first wave isn’t always the largest!
