This hazardous weather outlook is for the San Francisco Bay Area
and Central Coast

.DAY ONE...Today and Tonight

Some scattered showers will continue today into tonight. Gusty
southeast to east winds will persist near the coast and coastal
hills with gusts to 35 mph likely at times as low pressure deepens
off the coast. Scattered showers will continue overnight into
Tuesday.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Periods of light rain continue on Tuesday but with minimal impacts
expected. A strong front arrives Wednesday afternoon into
Wednesday night. Heavy rain will develop across the North Bay
first and then spread southward, wreaking havoc on the Wednesday
afternoon/evening commute. Strong winds will accompany the
frontal passage which could bring down trees and branches. The
heavy rain will likely lead to urban and small stream flooding as
the front moves through Wednesday night. On average 3-6 inches of
rain will be possible in the hills with 1-3 inches in the lower
elevations by Thursday morning with much of the rain falling
during a short window late Wednesday as the front moves through.

Expect rapid rises on small streams but large rivers are forecast
to remain well within bankfull.

High pressure builds Friday and Saturday with dry weather. Another
chance of light rain on Sunday.
