Wind and low humidity mean increased chance of fire across Western Washington

The National Weather Service on Wednesday was warning about heightened fire risk this week because of gusting winds and low humidity.

A “red flag” warning will be in effect from 6 a.m. Thursday (Sept. 11) to 5 p.m. Friday for several areas, including Puget Sound lowlands and the Cascades from Enumclaw south.

Forecasters said humidity was expected to drop to 20 to 30 percent, and winds could gust up to 25 miles per hour. That weather, coupled with dry brush after a summer that saw little rain, means an increased chance of fire.

“Fuels are starting out only marginally dry, but a single day of dry wind will push fuels, especially light fuels, into the critically dry category,” according to the warning.

A strong east wind will whip across Western Washington starting Wednesday night and blow through Thursday. The wind will decrease slightly Friday but still will be stronger than usual.

Temperatures will remain in the low to mid 70s until Saturday, when they will jump back into the low 80s, the Weather Service said.
