San Diego woke up Monday to brief heavy rain as winter storms buffeted California and brought flooding and heavy snow to the north.

Radar at the National Weather Service office in San Diego showed a large area of rain spreading over San Diego county at sunrise. Drivers were warned to expect delays and minor flooding.

Rainfall totals are expected to be light to moderate in the San Diego area, from a tenth of an inch along to coast to half an inch in the mountains. Highs will be in the mid 60s along the coast and low 60s farther inland.

Additional waves of rain are forecast to arrive Tuesday night and on Thursday.

“Periods of rain will come and go this week along with some strong winds in the mountains and deserts,” the weather services said. “A series
of three waves will bring rain, but no snow outside of the highest peaks.”

Northern California was expected to get up to 8 inches of rain and several feet of snow. Interstate 80 was closed by a mudslide near Truckee, and residents of Cambria were told to evacuate because of flash flooding.

One encouraging development because of the storms is that the Sierra snowpack that provides springtime water is now above normal for the first time in five years. The statewide measure on Friday was 103 percent.
