Flash flood warnings issued for Napa, Marin

Due to tonight’s major storm affecting all of the Bay Area region, the National Weather Service has issued a flash flood warning for Napa and Marin counties.

Corte Madera Creek has flooded. Ross Valley and San Anselmo residents have been advised to evacuate and seek higher ground.

“Much of this region is water-logged from the previous days rainfall and additional rainfall could easily lead to flash flooding,” reports the National Weather Service, adding, “Much of the California coast and the Sierras could see excessive rainfall through Wednesday morning.”

In San Francisco and the Peninsula, an urban/small stream flood advisory is in effect until 9:45 pm Tuesday.

As for pedestrians walking around the city (and elsewhere) this evening, be careful out there. The winds are picking up at ungodly speeds.
