I mean, the flooding in parts of the inner LA metro has been quite bad. The area around the 101/134/170 interchange has been a mess, with many cars getting stuck in floodwater.
Further out, there are full closures on I-10 in Thousand Palms, US 395 north of Victorville, CA 14 north of CA 58, CA 58 west of CA 14, and CA 178 through Kern Canyon. It is an absolute mess in the mountains.
Looks like a wonderful summer Sunday afternoon on the roads of Southern California.
I'm sure the LA and San Diego areas are awful, but of that the biggest single thing appears to be the full closure of Interstate 15 through Barstow. I haven't seen an exact reason yet but flooding would be a decent guess.
It's downed power lines, according to CalTrans.
I'm in San Diego, and it was raining pretty hard an hour ago, but very little wind. Seems like a typical winter storm, except for the temperature.
I do notice that I-8 EB going down into the low desert is closed, due to a rockslide. That's gonna suck, because it looks like 78 might be closed (zero traffic showing), so CR-S22 through Ranchita down to Borrego Springs is the nearest alternative. Even the Mexico routes 2 and 20 are closed. But in the
western part of San Diego County everything looks green on Google Maps.
Oh, it gets better. There was a period today when 8, 78, and S22 were all closed due to flooding or slides.
