Heavy Rain and Flood Watches as Atmospheric Rivers Target Northern California

Two atmospheric river systems are set to bring significant rainfall, potential flooding, and heavy Sierra snow through next week.

The National Weather Service has issued flood watches for multiple Bay Area counties, with heavy rain expected from Friday through Sunday.
Rainfall totals could reach up to 6 inches in the North Bay, 3-4 inches in the East Bay, and 2-3 inches in the South Bay, with localized flooding possible.
The Sierra Nevada is forecast to receive several feet of snow at higher elevations, with snow levels dropping as colder air arrives early next week.
Wind gusts exceeding 50 mph are predicted in mountainous and coastal areas, potentially causing downed trees and hazardous driving conditions.
A second, colder storm system is expected to bring additional rain and snow starting Monday, intensifying impacts across the region.
