* AFFECTED AREA...Fire Weather Zone 658 West Slopes of the North Cascades Generally above 1500 Feet, Fire Weather Zone 659 West Slopes of the Central Cascades Generally above 1500 Feet and Fire Weather Zone 661 East Portion of the Olympic Mountains. * THUNDERSTORMS...Thunderstorms are favored along the eastern slopes of the Olympic mountains and more so in the Cascades this afternoon and evening. Some brief heavy rain or isolated wetting rains are possible, but lightning strikes on very dry fuel are capable of new fire starts. * OUTFLOW WINDS...Outflow winds of 25 to 30 mph are possible. Outflow winds can occur ahead of and behind storms and cause erratic wind directions. * 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. With lightning occurrences having started earlier this week and thunderstorms expected again today, multiple days in a row of lightning strikes on our dry fuels could result in a critical number of new wildfires. * THUNDERSTORMS...A few lightning strikes occurred in the higher terrain of the Cascades mountains yesterday and that will resume this afternoon and evening. Multiple days in a row of lightning strikes on our dry fuels could result in a critical number of new wildfires.

* WHAT...Flash flooding and debris flows caused by excessive rainfall from thunderstorms is possible. * WHERE...A portion of North Central Washington, including the following counties, Chelan and Okanogan. * WHEN...From 11 AM PDT this morning through this evening. * IMPACTS...Heavy rainfall may result in flash flooding or debris flows in steep terrain, particularly near burn scar locations.
