An atmospheric river will bring heavy rainfall to lower elevations of California this week, and heavy snow to the Sierra Nevada mountains. Flash flooding, some of which may be locally considerable, will be a concern on the western foothills of the Sierra Nevada mountains through Tuesday. Landslides, rockfalls and mudslides are possible in the Southern California mountains. Read More >
Overview
An early season winter storm moved into the region late Wednesday, October 9, and brought widespread snow and gusty northerly winds. The highest snow totals fell in the northern Black Hills, with slightly lesser amounts on the plains. Northerly winds gusting near 50 mph created areas of blowing and drifting snow, especially on the South Dakota plains. Snowfall ended from west to east late Thursday and early Friday.
