The National Weather Service has issued a red flag warning for high fire danger due to low humidity and a dry east wind.
The warning is in effect for Seattle southward in the lowlands near Puget Sound/Kitsap County and the immediate coast. The warning was supposed to expire at 10 p.m. on Thursday, but was extended to 10 p.m. on Friday.
The warning is also in effect for the central and south Cascades foothills and west slopes of Olympics through Saturday night.
The weather service said the central and south Puget Sound lowlands will have wind gusts near 20 mph with low humidity.
A red flag warning means that critical fire weather conditions are occurring now or will shortly. A combination of strong winds, low relative humidity and warm temperatures will create potential for explosive fire growth.
The weather service said people should be extremely careful burning material and roadside fires will be a particular danger Thursday.
