Rain will start to develop and winds pick up as an expected low pushes into California.
S-SW winds 20-30 with gusts to 50 are possible at higher elevations and wind advisories are in place from 8p Tuesday into 10a Wednesday for interior and higher elevations in both SLO and SB county.
Rain begins tonight with some scattered activity Wednesday PM into early Thursday. 0.30 and 1.50 inches of rain is expected with higher amounts possible on the SLO county north coast.
North of the Bay Area this system is hitting hard with 3-8″ of rain already on the ground with 2-6″ more rain possible into Wednesday.
In Northern California, an Atmospheric River (AR) produced copious amounts of rain yesterday. The AR is expected to lift back northward today out ahead of a storm system. Heavy rain is expected today across Sonoma and Mendocino counties and the northern Sierra where another 4 and 8 inches of precipitation is possible today through tonight resulting in flood warnings for some Northern California rivers, like the Russian River.
A break in the rain on Friday.
A stronger low-pressure system arrives on Saturday. Models don’t entirely agree on potential with this system but it looks to have the atmospheric river to work with. .5-2.5″ of rain is possible with scattered rain possible on Sunday.
Interestingly the strongest of a string of storm is possible next Tuesday into Wednesday, that could deliver another 1-3″ of rain.
