Nicco says the South Bay, including places like Mountain View, won't get drenched until about 4 p.m.
The wet weather will turn to scattered light showers around 7 p.m.
"It will be a little breezy before the rain sets in, especially in higher elevations," said Nicco. "Expect light to moderate showers tonight through tomorrow."
The wet weather will move out of the Bay Area Wednesday by around 7 p.m.
Both storms are expected to bring a wide range of rainfall totals.
"From a tenth of an inch in the South Bay to three quarters of an inch in the North Bay," added Nicco. "We could get more than inch up in our mountains."
Temperatures will be cooler starting Wednesday before the Bay Area sees another chance of wet weather on Sunday, according to Nicco.
