Red Flag Warning issued August 17 at 8:09PM PDT until August 18 at 5:00AM PDT by NWS Pendleton OR

7 months 2 weeks ago
...STRONG TO SEVERE THUNDERSTORMS WILL IMPACT THE CASCADE MOUNTAINS TODAY, EXTENDING TO THE EASTERN SLOPES, WHILE SOUTHEASTERN OREGON SEES DRY, WINDY, AND UNSTABLE CONDITIONS... .A potent weather system will bring a myriad of impacts to the forecast area today. For the Cascade Mountains and east slopes, strong to severe thunderstorms will trek across primarily the spine of the Cascades starting in the afternoon down around central Oregon, advancing northward into the Washington Cascades by the evening. While storms along the Cascades are expected to be accompanied by a significant wetting rain, isolated to scattered storms extending into the east slopes and portions of the Columbia Basin will be much drier, leading to critical fire weather conditions due to abundant lightning with a lack of wetting rain. For southeastern Oregon, this same weather system will usher in hot and dry desert air, leading to breezy winds combined with low RHs and locally unstable conditions. Showers and storms are not anticipated to track as far east as southeastern Oregon. Users should note that OR641 and WA691 are under partial Red Flag Warnings. The Warned zones include only the western half of each zone, and not the entirety of the zone. * AFFECTED AREA...Fire Weather Zone 690 Kittitas Valley. * IMPACTS...Thunderstorms will be capable of producing frequent cloud-to-ground lightning and erratic, gusty outflow winds. This combination will promote conditions conducive to new fire starts and rapid fire spread for new and existing fires. * THUNDERSTORMS...Abundant lightning with frequent cloud-to- ground lightning strikes. * OUTFLOW WINDS...Gusty winds up to 50 mph.
