A tropical storm will move into San Diego this afternoon, bringing scattered rain through Friday, according to the National Weather Service.
The large mass of warm air will melt all the snow in the mountains and drop up to a half inch of rain in the coastal and inland areas of the county, forecaster Wally Cegiel said. Mountain areas could receive up to an inch, and only a chance of rain is seen for the deserts.
“We’ll get showers periodically, not continuously,” Cegiel said. By the weekend, skies will turn partly cloudy and become sunny on Sunday and Monday, he said.
Temperatures at the beach today and Friday are expected to range from 58 to 63, with the surf 1 to 3 feet. Winds will be 8 to 16 m.p.h. and the water temperature is near 57 degrees.
Highs in the coastal strip and inland valleys will range from 63 to 68 today and Friday, Cegiel said. The nighttime lows are expected to be 48 to 55 in the coastal areas, 43 to 50 in the inland valleys.
The mountains will experience gusty, southwest winds up to 25 m.p.h. and daytime highs of 45 to 50 today and Friday, Cegiel said, with nighttime lows dropping to 37 to 43.
A chance of showers is forecast for the deserts today and Friday. Temperatures are expected to range from 58 to 63 both, days with nighttime lows of 40 to 48.
