“Then comes your Saturday…scattered showers and even some breaks with sunshine,” said Gonzales. “It will be rainbow weather.”
Heavy rain is expected to linger Sunday, leaving some impressive rain totals for the weekend.
However, “the intensity of both the rain and the wind will likely be lower than what we had today,” said Deanno.
“A lot the urban areas of the North Bay will see four to eight inches,” said Gonzales. “We’ll see two to four inches around San Francisco, with up to six inches in the Santa Cruz Mountain.”MORE NEWS: Fire Danger: Cal Fire Suspends Burn Permits For Monterey, San Benito Counties
