The National Weather Service in Seattle has issued a Red Flag Warning for dry thunderstorms and gusty outflow winds, which is in effect from 8 AM to 11 PM PDT Wednesday. * AFFECTED AREA...Fire Weather Zone 652 West Portion of the Olympic Mountains and Fire Weather Zone 661 East Portion of the Olympic Mountains. * THUNDERSTORMS...Scattered thunderstorms with LAL 3 are expected to develop early as late morning and most likely during the afternoon and evening hours. * OUTFLOW WINDS...Gusty and erratic winds are possible in the vicinity of any thunderstorms that develop. * IMPACTS...Scattered lightning in dry fuels can cause multiple fire starts. Thunderstorms can also bring sudden sharp wind shifts on existing fires, causing rapid changes in a fire's rate of spread and direction of spread. Thunderstorm outflow winds can be a threat for several hours following the start of a new lightning-caused fire. If a fire were to begin, air quality may diminish in the surrounding area.

Scattered thunderstorms containing little to no rainfall will be possible over much of North Central Washington Wednesday afternoon and evening. Any thunderstorms have the potential to produce gusty outflow winds that could travel quite a distance from the thunderstorm source. Isolated thunderstorms are possible elsewhere across Eastern Washington and North Idaho. The National Weather Service in Spokane has issued a Red Flag Warning for thunderstorms, which is in effect from noon Wednesday to midnight Wednesday night. * Affected Area: Fire Weather Zone 707 Western Columbia Basin and Fire Weather Zone 708 Eastern Columbia Basin - Palouse -Spokane Area. * Haines: High level haines of 6, which is very high. This means very dry and unstable conditions exist. * Humidity: 12 to 19 percent. * Outflow Winds: Gusty and erratic winds are possible with any thunderstorms that develop. Gusty winds from thunderstorms that develop over the Cascades and north central Washington could send an outflow boundary across the Columbia Basin, Palouse and Spokane area. * Thunderstorms: Thunderstorm coverage at this time looks to be isolated across the Basin, Palouse and Spokane area. * Impacts: Unstable conditions could lead to plume dominated fires. Rapid fire spread with any new or existing fires due to the gusty wind potential. These conditions may overwhelm initial attack capabilities.

* AFFECTED AREA...Fire Weather Zone 658 West Slopes of the North Cascades Generally above 1500 Feet and Fire Weather Zone 659 West Slopes of the Central Cascades Generally above 1500 Feet. * THUNDERSTORMS...Scattered thunderstorms with LAL 3. * OUTFLOW WINDS...Gusty and erratic winds are possible in the vicinity of any thunderstorms that develop. * IMPACTS...Scattered lightning in dry fuels can cause multiple fire starts. Thunderstorms can also bring sudden sharp wind shifts on existing fires, causing rapid changes in a fire's rate of spread and direction of spread. Thunderstorm outflow winds can be a threat for several hours following the start of a new lightning-caused fire. If a fire were to begin, air quality may diminish in the surrounding area.
