Flooding has disrupted transportation and daily life across the Bay Area, with roads closed and vehicles stranded. Drivers attempting to navigate floodwaters risk vehicle damage and personal safety. Coastal areas, including Mill Valley and San Francisco's Embarcadero, are particularly vulnerable. The ongoing El Niño conditions are expected to sustain elevated water levels, increasing the likelihood of further flooding and property damage. Residents in low-lying areas should remain vigilant as the advisory continues.
