A series of storms headed toward San Diego will bring heavy rains expected to last much of the work week.
Showers started developing during the overnight hours Sunday and steady rain continued on Monday morning, bringing a slick commute across San Diego County.
Two or more storm systems will cross San Diego County starting Tuesday -- the heaviest storm expected -- and may last as long as Friday, NBC 7's Greg Bledsoe forecasts. Rainfall totals of at least 1 inch are expected, though Bledsoe says there is a good chance San Diegans will see more rainfall.
The majority of rain will fall between Tuesday and Thursday, NBC 7 meteorologist Jodi Kodesh said.
A flash flood watch is in effect for San Diego County valleys and mountains from Tuesday morning to Wednesday night.
Temperatures will drop later in the week, meaning mountains should get more snow as the storm wears on, Kodesh added.
The Sierras near Mammoth are already getting quite a bit of snow, as of Saturday, and local mountain temperatures will be in the 30s and 40s with a good chance of snow near home later in the week.
In addition, a high surf advisory is in effect until 10 p.m. Friday, with sets as tall as 15 feet expected on the coast.
