Fire Weather Planning Forecast for Western Washington
National Weather Service Seattle WA
741 AM PDT Sat Aug 30 2025

.DISCUSSION...A trough of low pressure offshore will keep
temperatures cooler, but is unlikely to produce precipitation across
the area today. A trend toward much warmer and continued dry
conditions are expected early next week as an upper level ridge
strengthens over the region. Relative humidity values in the Cascades
and portions of the Olympics are expected to approach critical
thresholds toward the middle of next week with the potential for poor
overnight recoveries.

 Forecast for 20 foot wind speed (valleys and ridge tops) are 10
 minute averages reflecting RAWS winds.
