As Southern California continues to dry out and dig out from the winter storm that battered the region over the past three days, another storm system is poised to bring even more precipitation.

A series of weak storms will bring periods of rain and mountain snow through Wednesday.

“Each particular system will be weak, but will build up one another, bringing some decent rain and snow totals to the area,” the National Weather Service reports, though precipitation totals are not forecast to be near as extreme as the recently departed storm.

The next storm could extend closures of mountain roads while flooding may occur during heavier downpours, according to NWS.

A winter weather advisory is in effect through Wednesday evening for periods of light to moderate snow, occasionally mixing with winds at times, according to NWS.

Meteorologists say the storm will come in three separate waves. The first is expected to bring .50 to 1 inches of rain across coastal and valley areas with 1 to 2 inches of rain in the mountains and foothills. The next two waves will bring lighter precipitation.

Snow levels will range between 3,000 and 4,500 feet.

“Snowfall accumulations of 4 to 10 inches with local amounts to 12 inches, primarily from late today through Wednesday evening and highest across the Los Angeles County mountains,” NWS said.
