Fire Weather Planning Forecast for Western Washington
National Weather Service Seattle WA
247 PM PDT Tue Sep 2 2025
...HEAT ADVISORY IN EFFECT UNTIL 5 PM PDT THURSDAY FOR PORTIONS OF
INTERIOR WESTERN WASHINGTON...
...RED FLAG WARNING IN EFFECT FROM NOON TO 9 PM PDT WEDNESDAY FOR
HOT, DRY AND UNSTABLE CONDITIONS FOR FIRE WEATHER ZONES 658 AND
659...
.DISCUSSION...Dry and unstable conditions will continue across the
mountains through Wednesday with high pressure overhead. While
onshore flow will bring good recoveries to the lowlands, this will
bring poor to moderate RH recoveries in the Cascades on the slopes
and ridgetops, with elevated to critical fire weather conditions
through Wednesday. Later in the week, monsoonal moisture may move
into the region to boost the chances for isolated thunderstorms,
especially near the Cascades, but confidence in the specific timing
and coverage remains low.
Forecast for 20 foot wind speed (valleys and ridge tops) are 10
minute averages reflecting RAWS winds.
