SAN DIEGO Rain fell steadily around San Diego County Monday for the fourth consecutive day, causing a soggy morning commute.
There were 63 mishaps reported on the county's highways and freeways between midnight and 10 a.m., with more than half of those occurring between 6 and 9 a.m., according to the California Highway Patrol.
In dry weather, the CHP typically receives between 50 and 75 accident reports over a 24-hour period.
"Strong Pacific storm systems will bring high rain amounts to Southern California through at least Wednesday,'' according to the National Weather Service.
The agency advised that although the rainfall will be fairly steady Monday, hourly rainfall rates were not likely to be intense. However, on Tuesday and Wednesday, heavier rainfall could cause flash flooding, according to the Weather Service.
A flash flood watch was scheduled to go in effect from noon Monday through Wednesday afternoon.
From Friday night through Sunday night, up to an inch-and-a-half of rain fell along the coast, 1 to 2 inches fell in the valleys, 3 to 6 inches fell in the mountains and about a half-inch fell in the deserts, the Weather Service estimated.
Snow levels will be above 8,000 feet through Tuesday but a brief period of snow down to 6,000 feet was possible Tuesday night into Wednesday, as a cold front comes through, forecasters said.
