An atmospheric river storm system expected to deliver a blow to Northern California this week has triggered a flood watch and wind advisory in parts of the Bay Area.
The flood watch will be in effect in Sonoma, Napa and Marin counties from 4 a.m. Wednesday through 5 a.m. Friday, according to the National Weather Service.
Excessive rainfall could cause creeks, streams and rivers to rise, resulting in flooding in some areas, the weather service said. Ponding could also occur in low-lying areas and on roadways.
