Heavy Rain and Flash Flooding Concerns in California; Heavy Snow in the Sierra

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

A strong upper-level disturbance brought heavy snow to portions of the Black Hills and western South Dakota from the afternoon of March 13th through the morning of March 14th. Highest snowfall totals were observed in the central and southern Black Hills and into the southern foothills, with around a foot of snow reported from near Custer, east to Hermosa, and south to Buffalo Gap. Several inches of snow were also observed across portions of the western and central South Dakota plains.

Here is a cool video received from Piedmont, SD that shows the drifts "coming alive" at night. Scroll down and click the tabs for pictures and radar.
