Although the majority of the precipitation is expected tonight and Tuesday, National Weather Service forecasters said periods of light to moderate rain would be likely over the mountains, the valleys and the coast through Wednesday afternoon.
“Showers look to gradually increase this afternoon through early evening, with the majority of rain shower activity occurring late this evening through most of Tuesday,” according to the weather service. ``Showers will gradually diminish during the day Wednesday.''
Rainfall amounts are expected to range from less than a quarter-inch in the deserts to about half an inch near the coast to as much as two inches on the coastal mountain slopes.
Forecasters predict .62 inches of rain would fall in San Diego by late Wednesday morning.
The storm will lead to slick roads and other travel hazards. Urban and small stream flooding could also be possible in areas that get heavy rain, forecasters said.
