One round of wet weather has already swept through California, but another blast of Pacific moisture could trigger significant flooding across the region.
24 Hour Rainfall. Isolated pockets of 3″ of rain could be found along the coast after the first wave of showers came through. Bakersfield stayed generally dry, while Los Angeles picked up just under 1″ of rain at the airport.
Travel Concerns. Roads were wet late Wednesday night, leading to numerous crashes across Los Angeles County. The San Gabriel Valley Tribune reports on the road conditions and recent rain:
“The California Highway Patrol logged 77 crashes in the areas of Los Angeles County it covers from 10 p.m. Wednesday to 2 a.m. Thursday. In Pasadena, collisions involving big rigs affected both sides of the 210 Freeway. Three separate collisions occurred around 11:35 p.m. Wednesday on the eastbound 210 Freeway past Lincoln Avenue. Lanes were closed for about five hours . . .”
Continued Rain. This next batch of wet weather could push 4″ into southern California by Saturday night. Numerous areas are on the lookout for flash flooding as the ground won’t be able to soak in this large amount of rain in a short amount of time. [Image courtesy WeatherBell.com]
Flash Flood Potential. This forecast map shows the flash flood guidance for one hour worth of rain. If Los Angeles picks up between 0.5″-1.0″ in just one hour, flash flooding will become an issue. This is quite likely as some stronger bands of rain & thunderstorms develop along the warm front as it pushes onshore.
