The National Weather Service in Seattle has cancelled the Red Flag Warning. The threat of lightning from scattered thunderstorms this afternoon has ended. A localized shower or thunderstorm may develop this afternoon, but coverage is expected to be very limited. $$ WAZ658-230300- /O.CON.KSEW.FW.W.0006.000000T0000Z-260823T0300Z/ West Slopes of the North Cascades Generally above 1500 Feet- 240 PM PDT Sat Aug 22 2026 ...RED FLAG WARNING REMAINS IN EFFECT UNTIL 8 PM PDT THIS EVENING FOR LIGHTNING AND GUSTY OUTFLOW WINDS FOR FIRE WEATHER ZONE 658... * AFFECTED AREA...Fire Weather Zone 658 West Slopes of the North Cascades Generally above 1500 Feet. * LIGHTNING...Scattered thunderstorm coverage is possible across the North Cascades. * OUTFLOW WINDS...Any storms that develop will be capable of gusty and erratic outflow winds between 20 and 40 miles per hour. Outflow winds can occur ahead of and behind storms and cause erratic wind directions. * IMPACTS...Scattered lightning in dry fuels can cause multiple fire starts. Thunderstorms can also bring sudden sharp wind shifts on existing fires, causing rapid changes in a fire's rate of spread and direction of spread. Thunderstorm outflow winds can be a threat for several hours following the start of a new lightning-caused fire. If a fire were to begin, air quality may diminish in the surrounding area. PRECAUTIONARY/PREPAREDNESS ACTIONS... A Red Flag Warning means that critical fire weather conditions are either imminent or occurring now. Any fires that develop will likely spread quickly. Outdoor burning is not recommended. && $$
