Update 1 p.m Friday: Due to the rain, between midnight and 10 a.m., the California Highway Patrol logged 119 crashes. By comparison, the CHP generally responds to 50-75 accidents on local freeways and highways over an entire day of dry weather.
Rain fell in parts of the region beginning Thursday as a low-pressure system moved south off the California coast, and forecasters expect it to continue throughout the weekend, despite the summery weather at the beginning of the week.
There is a certainty of rain Friday, expected to be heavier as the day progresses. Temperatures will fall to the upper 50s in Coronado by Sunday, with lows by then also slipping to the upper 40s.
The sun will return Monday, but the cool temperatures are set to remain.
Cooler weather, clouds and more rain are expected Friday as the low pressure system moves across northern Baja California and the most southern reaches of California, according to the National Weather Service.
Bands of heavier showers Friday afternoon into the evening could drop from a half-inch up to an inch of rain over a six-hour period.
“Dynamics to help support shower development across southwest California are strongest though this morning and then again late Friday through early Saturday,” according to the NWS.
Lighter amounts, mainly near the mountains, could fall as a colder system approaches from the northwest late Saturday through early Sunday. Gusty winds in the mountains and deserts are also expected.
The showers should decrease late Saturday through early Sunday, but more rain along and west of the mountains is expected through Monday night.
