This second weekend of the new year is bringing downpours along the coast and snow in the mountains, much the same as the first week of 2019.

A south-moving storm began dousing the county with rain and snow early Saturday morning, the National Weather Service office in San Diego reported.

Rain-slicked highways caused two big rigs to crash in separate incidents on Interstate 805 in Chula Vista. A fire truck responding to the accidents also crashed.

Most coastal, inland-valley and mountain locales will get anywhere from a quarter-inch to three quarters of an inch of precipitation, and the deserts likely will receive between a quarter-inch and a half-inch of rain over the day, meteorologists predicted. The snow level is expected to reach around the 5,500 feet.

The weather service has issued a high surf advisory that will be in effect from 10 a.m. Saturday morning until noon Sunday.

The rainfall, which may be heavy at times, should begin dissipating later Saturday morning and the storm system is expected to leave the region by Sunday evening, according to the weather service.

Another period of scattered showers is in the forecast next week for the far southern reaches of California, possibly beginning as early as Monday and continuing, off and on, as late as Friday.
