With fires already burning and forests full of fuel a red flag warning for thunderstorms has been issued for eastern Washington and north Idaho.

According to the National Weather Service, a surge of monsoonal moisture combined with an approaching disturbance will bring isolated dry thunderstorms to extreme eastern Washington and the Idaho Panhandle late Thursday night and into Friday morning.

The weather service says the threat will end over the Palouse and Spokane area and the northern Idaho Panhandle late Friday morning. However, in the Idaho Panhandle mainly south of Interstate 90 thunderstorms will become wetter during the day Friday, but also increase in areal coverage to scattered.

The National Weather Service in Spokane has issued a Red Flag Warning for thunderstorms, which is in effect from 11 PM this evening to 5 PM PDT Friday.

Thunderstorms: Isolated Thunderstorms with little or no rain will develop late tonight and continue into Friday morning north of Interstate 90.

The thunderstorm threat will continue south of Interstate 90 through Friday afternoon with storms becoming scattered and wetter during the afternoon.

* Outflow Winds: Local gusts to 30 mph tonight and to 40 mph Friday afternoon..

* Impacts: Lightning will efficiently ignite dry fuels around the region.


A Red Flag Warning means that critical fire weather conditions are either occurring now….or will shortly. A combination of strong winds…low relative humidity…and warm temperatures can contribute to extreme fire behavior.

Last weekend, thunderstorms touched off more than a dozen forest fires.
