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.
