A modest storm will douse the Southland Wednesday, but a much more powerful system will strike the region Friday, raising concerns of mud slides in communities below mountain slopes stripped bare by wildfires.
Light rain is likely across Ventura and Los Angeles counties this afternoon and this evening, the NWS said in an advisory. More showers are possible Thursday morning and up to a half-inch could fall. Many areas can expect between one-tenth and one-third of an inch, according to the National Weather Service.
The snow level is expected to remain above 7,000 feet during today's storm, but it could fall as low as 6,000 feet on north-facing slopes by late tonight.
A more powerful storm is expected Friday afternoon, with showers likely to linger into Saturday, according to the NWS advisory.
Across Ventura and Los Angeles counties, rainfall amounts produced by this week's second storm are expected to range between three-quarters of an inch and an inch-and-a-half, although up to two-and-a-half inches of rain are possible in some foothill and mountain locations, the NWS said.
The snow level resulting from Friday's storm will remain high initially but could fall to between 4,000 and 5,000 feet Friday night and early Saturday, according to the NWS advisory.
