NOAA Current Watches

* WHAT...Flash flooding and debris flows caused by excessive rainfall continue to be possible. The greatest concern remains over the 2024 burn areas associated with active wildfires, but there is also a small probability that rainfall rates could approach threshold values over burn areas from previous years. * WHERE...Portions of Oregon, including the following areas, Cascades of Lane County, Cascades of Marion and Linn Counties and North Oregon Cascades and southwest Washington, including the following area, South Washington Cascades. * WHEN...From 2 PM PDT this afternoon through late tonight. * IMPACTS...Heavy rainfall over Cascade burn areas during the period of the watch. Residents near the 2024 burn areas associated with active wildfires should prepare for potential flooding impacts. Be sure to stay up to date with information from local authorities. Heavy rainfall could trigger flash flooding of low-lying areas, urbanized street flooding, and debris flows in and near recent wildfire burn scars. * ADDITIONAL DETAILS... - National Weather Service Meteorologists are forecasting heavy rainfall, which may lead to flash flooding and debris flows over recent burn areas in the Cascades. Hourly rainfall rates up to 0.75 inches per hour will be possible. - http://www.weather.gov/safety/flood Flash Flood Watch 2024-08-17T03:59:00-07:00 2024-08-17T03:59:00-07:00 2024-08-17T14:00:00-07:00 2024-08-17T18:00:00-07:00 Actual Alert Met Future Severe Possible North Oregon Cascades; Cascades of Marion and Linn Counties; Cascades of Lane County; South Washington Cascades SAME 041005 SAME 041027 SAME 041051 SAME 041047 SAME 041043 SAME 041039 SAME 053059 SAME 053015 SAME 053011 UGC ORZ126 UGC ORZ127 UGC ORZ128 UGC WAZ211 AWIPSidentifier FFAPQR WMOidentifier WGUS66 KPQR 171059 NWSheadline FLASH FLOOD WATCH REMAINS IN EFFECT FOR CASCADES BURN AREAS FROM 2 PM PDT THIS AFTERNOON THROUGH LATE TONIGHT BLOCKCHANNEL EAS BLOCKCHANNEL NWEM BLOCKCHANNEL CMAS EAS-ORG WXR VTEC /O.CON.KPQR.FF.A.0001.240817T2100Z-240818T0900Z/ eventEndingTime 2024-08-18T09:00:00+00:00 expiredReferences w-nws.webmaster@noaa.gov,urn:oid:2.49.0.1.840.0.7c8f23fe5afa54e25bf119b030f775b830027db6.001.1,2024-08-16T15:12:00-07:00 w-nws.webmaster@noaa.gov,urn:oid:2.49.0.1.840.0.c662c9719a4f6d09c95b3e6ac5be486ad173fb14.001.1,2024-08-16T05:44:00-07:00 w-nws.webmaster@noaa.gov,urn:oid:2.49.0.1.840.0.cc607ed15516ea98c94e35a1831bff27fbd01559.001.1,2024-08-15T13:46:00-07:00

...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. The National Weather Service in Pendleton has issued a Red Flag Warning for abundant lightning, which is in effect from 5 PM this afternoon to 2 AM PDT Sunday. The Fire Weather Watch is no longer in effect. * AFFECTED AREA...Portions of Fire Weather Zone 691 Lower Columbia Basin. The easternmost extent of the Warning ends at a line extending from Hanford to Prosser. * 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.
