A powerful storm that hit last night will be followed by an even more powerful system on Friday, with more to come over the weekend.
Umbrella weather be with us possibly into Tuesday when the threat of more rain vacates the county. After a night of off-and-on showers we're looking at more of the same this morning, with a steadier, light rain later on Friday. On Friday, the first frontal system will depart to the east and the second will prepare to come ashore from the west.
Rainfall amounts have been all over the place, from about a one-tenth of an inch to just under an inch. The heaviest downpours have been in North County and in the mountains. So far, there's been little if any snow in San Diego County, but that should change Friday night. This will be a much colder system and we could end up with as much as six inches on Palomar Mountain and Mount Laguna by Sunday. Rainfall amounts have been upgraded a bit. Projections are for at least one-half inch near the coast and twice that in the foothills.
Temperatures will remain cool, with highs only in the low 60s. There will be freezing temperatures above 4,000 feet on Friday night, so ice could be a problem Saturday and Sunday on the mountain roads and through the passes. On the west side of the county, we're expecting rough seas, with storm surf up to 8 feet and astronomical high tides of 7 feet or more. This combination could produce some coastal flooding.
Friday's commute proved to be a sloppy one as a result of the rain. On Interstate 8 where it meets the state Route 163 connector, a vehicle left the roadway and slammed into a light pole. The California Highway Patrol had to stop traffic to remove the pole.
There was also a mess on state Route 94 westbound near the Interstate 805 connector, where a four-vehicle crash was reported. On Intertate 5 north near the Main Street off-ramp, a mud- and rock slide was reported.
On Interstate 8 west near state Route 125, traffic was halted and diverted to SR-125 for about an hour while officials tended to an accident and cleared debris after a vehicle spun out and was struck by several other cars. The CHP finally reopened the freeway at 6:30 a.m.
