From west to east, a volatile mix of wild weather this week. The West will deal with a bomb cyclone delivering flooding rain, snow, and a wintry mix, amid severe weather in the central US, while the East braces for a nor’easter.

Atmospheric river delivering flooding rain, debris flow, and evacuations to West

Mandatory evacuations have been ordered and part of the Western US, particularly in recent burn areas, under the threat of mud and debris flows.

The National Weather Service warned that parts of northern California could see “potentially historic” rainfall as storms produced debris flow and mudslides over the weekend. The area saw flooding and blocked roadways; one boulder flow completely blocked both lanes of a highway in Butte County, the Washington Post reported.
