Heat Advisory issued August 23 at 10:20PM PDT until August 26 at 5:00AM PDT by NWS Seattle WA

Effective: Sat August 23, 2025, 10:20 PM
Expires: Sun August 24, 2025, 6:30 AM

* WHAT...Hot conditions with high temperatures ranging from the mid 80s to 90s expected and low temperatures mostly in the 60s. This will pose a moderate risk of heat-related illness. * WHERE...Portions of northwest and west central Washington. * WHEN...Until 5 AM PDT Tuesday. * IMPACTS...Heat will significantly increase the risk of heat-related illnesses for those who are sensitive to heat, especially those without effective cooling or adequate hydration.

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances. Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1. For sheltering information and other human services in your area, dial 2 1 1 during business hours or visit wa211.org anytime.

Red Flag Warning issued August 23 at 10:25PM PDT until August 24 at 9:00PM PDT by NWS Seattle WA

Effective: Sat August 23, 2025, 10:25 PM
Expires: Sun August 24, 2025, 6:30 AM

* AFFECTED AREA...Fire Weather Zone 661 East Portion of the Olympic Mountains. * RELATIVE HUMIDITY...As low as 20 to 25 percent. * TEMPERATURES...Up to 90 to 95. * STABILITY...Unstable conditions can be expected. * IMPACTS...A dry and unstable air mass with warm temperatures can contribute to active fire behavior. In western Washington, significant growth on existing fires takes place under such conditions. If a fire were to begin, air quality may diminish in the surrounding area.

A Red Flag Warning means that critical fire weather conditions are either imminent or occurring now. Any fires that develop will likely spread quickly. Outdoor burning is not recommended.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
