A cold low-pressure system is expected to move through southern California Sunday Jan. 6, the National Weather Service announced today.
Light to moderate precipitation, wind gusts and snow will likely accompany the storm.
The majority of rainfall will impact areas along and west of local mountains, NWS officials reported.
The main period of rainfall is expected Sunday morning with showers lingering into Sunday afternoon.
Rainfall totals may reach one-half inch on the coastal mountain slopes, forecasters said.
Showers will last longer in San Diego County than areas further north.
Forecasters said thunderstorms are likely Sunday afternoon due to cold air over the region.
Snow levels will lower to 4,500 feet to 5,000 feet Sunday and drop to 4,000 feet Sunday night with local snowfall of 2-3 inches possible, mainly above 5,000 feet.
Winds are expected to blow from the west in the mountains and deserts with the strongest gusts to hover around 45 miles per hour Sunday afternoon.
Officials warn driving through the mountains may be difficult at times due to locally reduced visibility, slick roads, gusty winds and snow.
