Spring is coming, and it has company.
Officially, the new season begins at 4:21 p.m. Sunday, or about the same time as a huge, potentially dangerous rain storm.
While San Diego may see some light showers during the early afternoon, the heavy stuff is expected to start up between 4 and 6 p.m.
How wet is wet?
Initial forecasts are calling for between one and two inches for the coast and valleys and maybe twice that in the foothills and mountains.
Above 5500-foot elevation, the area could get between 4 inches and a foot of snow. This, along with gusty winds, should make for hazardous driving anywhere in the county Sunday night, but especially in the higher elevations of the mountains where blizzard conditions are possible before midnight.
A Flash Flood Watch has already been posted for the majority of the county from the coast to the mountains.
There is also a high wind advisory starting midday Sunday through early Monday. This has prompted a gale warning and small craft advisory for boaters.
Monday will be partly sunny with showers likely, primarily before 11 a.m., with a temperature high near 59 degrees, according to the National Weather Service.
