Red Flag Warning issued August 27 at 1:37PM PDT until August 28 at 9:00PM PDT by NWS Seattle WA

Effective: Wed August 27, 2025, 1:37 PM
Expires: Wed August 27, 2025, 9:45 PM

* AFFECTED AREA...Fire Weather Zone 658 West Slopes of the North Cascades Generally above 1500 Feet, Fire Weather Zone 659 West Slopes of the Central Cascades Generally above 1500 Feet and Fire Weather Zone 661 East Portion of the Olympic Mountains. * THUNDERSTORMS...Thunderstorms are favored along the eastern slopes of the Olympic mountains and more so in the Cascades from this afternoon and evening and again Thursday into Thursday night. Some brief heavy rain or isolated wetting rains are possible, but lightning strikes on very dry fuel are capable of new fire starts. * OUTFLOW WINDS...Outflow winds of 25 to 30 mph are possible. Outflow winds can occur ahead of and behind storms and cause erratic wind directions. * IMPACTS...Scattered lightning in dry fuels can cause multiple fire starts. Thunderstorms can also bring sudden sharp wind shifts on existing fires, causing rapid changes in a fire's rate of spread and direction of spread. Thunderstorm outflow winds can be a threat for several hours following the start of a new lightning-caused fire. If a fire were to begin, air quality may diminish in the surrounding area. With lightning occurrences having started Tuesday and thunderstorms expect for two more days, multiple days in a row of lightning strikes on our dry fuels could result in a critical number of new wildfires. * THUNDERSTORMS...Multiple lightning strikes occurred in the higher terrain of the Cascades mountains yesterday afternoon and evening and that will resume this afternoon and evening. Multiple days in a row of lightning strikes on our dry fuels could result in a critical number of new wildfires.

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.
