After a sunny and warm Sunday, the San Jose area is set to experience a wet and unsettled weather pattern starting Monday, with rain, isolated thunderstorms, and gusty winds expected to continue through Wednesday. The National Weather Service has issued small craft advisories for Monterey Bay and warned of possible minor urban flooding due to the heavy rainfall.

Why it matters

The incoming weather system could impact daily routines, commutes, and outdoor activities in the San Jose region over the next few days. Residents will need to prepare for wet roads, slower traffic, and potential flooding in some areas.

The details

According to forecasts, San Jose will see temperatures reach the mid-70s Fahrenheit on Sunday before a Pacific weather system moves in on Monday.
