The National Weather Service has issued numerous flash flood watches for areas near many of the recent California wildfires. Heavy rain could bring ash and debris flows to locations below recently burned areas. At 8:37 a.m. on Saturday the NWS had not listed any major flash flood warnings in Oregon or Washington.
The atmospheric river combined with a bomb cyclone are bringing massive amounts of precipitation to areas of Northern California, Oregon, and Washington.
Precipitation accumulated over the 48-hour period ending at 8:56 a.m. PDT Oct. 23 showed approximately 1 to 2 inches near the Dixie Fire, one-half to 1 inch near the Caldor Fire, and 1 to 3 inches in northwestern California near the McCash, Monument, and River Fires. About 1 to 2 inches were recorded near the fires of 2020 in the Napa and Santa Rosa area, and up to 3 inches at the Doe and Hopkins Fires of 2020.
And more is on the way.
