Locally heavy rainfall will continue on Wednesday for coastal areas of Southern California. Snow will continue across the Sierra Nevada with snow levels dropping to 4000 ft. High elevation snow will develop across the Four Corners region.
A second cold front will move through Southern California on Wednesday resulting in the continued threat for widespread rainfall and high elevation snowfall. An additional 1-2 inches of rain (especially over the coastal mountains) will result in the continued threat for localized flooding and flash flooding. Mudslides may also become a concern. Elevations above 6000 feet will experience precipitation in the form of snow. One to two feet of total snowfall accumulation is possible above 6000 feet in elevation from Tuesday through Thursday.
Continued accumulating snowfall is expected across the Sierra Nevada with snow levels falling to around 4000 feet.
An area of low pressure will advance eastward through the Four Corners region with several inches of snow possible in the higher elevations.
