Rain Incoming, But Not a Ton

Some of the first real rain since spring will be drizzling over the Bay starting Wednesday and continuing into Thursday, but Southern California will be getting the brunt of the incoming storm.A passing shower is possible Wednesday morning or afternoon in SF, with rain likelier to come later on Wednesday night and into Thursday. The National Weather Service says there s a sub-30% chance of a passing thunderstorm at some point, and they forecast very little rain accumulation in San Francisco proper in the range of one-tenth to one-quarter of an inch. Widespread beneficial rain is expected tonight through Thursday with a low potential for thunderstorms over the Big Sur coast. Slick roadways and minor nuisance flooding are possible, and high rain rates over the burn scars may lead to debris flows. #CAwx https://t.co/G1vIFLw5zI NWS Bay Area (@NWSBayArea) October 21, 2026 The Big Sur coast will see heavier rain today and tomorrow, while Southern California will get even more.As th
