Overnight Storm Brings Heavy Rain To San Diego County

A storm system that brought light rain to San Diego County, and snow in at least one high-elevation mountain area, will linger over southern California this morning before exiting by midday, according to the National Weather Service.

Scattered showers could fall in coastal areas, the inland valleys and the mountains this morning, but no rain is expected in the deserts, forecasters said.

The chance of measurable precipitation is 40% in coastal and inland valley areas, while the mountains have a 30% chance.

A winter weather advisory was extended through 8 a.m. today in the San Diego County mountain communities above 4,000 feet.

As of 9 p.m. Thursday, Birch Hill on Palomar Mountain had received 2 inches of snow.

Snow levels will be around 3,500 feet this morning, meaning trace amounts of snow could fall in the mountains until 10 a.m. Friday, forecasters said.

NWS officials advised motorists to drive with caution because visibility could be limited at times and snow or ice could cover roads.

Dry weather is expected by this afternoon and temperatures will warm up through the start of next week, forecasters said. There will be a slight chance of rain everywhere except the deserts on Sunday, then dry weather is expected through at least Friday next week.
