Driven toward the Bay Area by a surging jet stream, a winter storm system -- carrying with it a Cat. 4 atmospheric river -- rapidly approached the West Coast Monday, triggering a variety of alerts and warnings.

Among the alerts issued by the National Weather Service was a flood watch from late Monday night through Tuesday afternoon for cities including San Francisco, Watsonville, Pacifica, Santa Cruz, Scotts Valley and Boulder Creek.

"Localized flooding will likely occur, particularly in urban areas where ponding on roadways or poor drainage is a common issue," weather service forecasters said. "Excessive runoff may result in flooding of rivers, creeks, streams and other low-lying flood prone locations. Commuters should plan on a wet trip on Tuesday and allow for extra time to arrive at their location."
