San José officials are bracing for impact as an atmospheric river threatens up to two inches of rain, with strong winds forecasted to shake the city and its surroundings within 24 hours. According to the City of San José, the deluge is expected to swell the Santa Cruz Mountains and, consequently, the Guadalupe River, triggering an official proclamation of local emergency. The city’s emergency response teams are on high alert, coordinating with Valley Water, the National Weather Service, and other key partners to prepare for the storm’s onslaught.
