Rainstorm Hits Bay Area, Treacherous Commute Expected Tonight
UPDATE: A severe rainstorm is set to hit the Bay Area around 12:00 PM today, with scattered showers and a potential for thunderstorms, which could significantly impact the evening commute. Meteorologists warn that road conditions may be treacherous, especially during rush hour.
The rainstorm, described as a “notable early season storm,” is moving slowly across the region and is expected to bring rainfall to even the driest areas. This weather event follows the recent announcement from federal scientists confirming the onset of La Niña, indicating cooler ocean temperatures off the coast of South America, which could lead to drier conditions this winter in California.
According to the National Weather Service, the North Bay can expect rain starting this morning, with San Francisco bracing for the storm’s arrival around noon. Roger Gass, a meteorologist with the NWS, warns that while the morning commute should remain unaffected, drivers should prepare for hazardous conditions this evening.
“Be mindful of water on the roadways as heavier rain showers can cause downpours,” Gass cautioned. He emphasized that the storm’s impact will be felt most acutely during peak commuting hours. With a 20% to 25% chance of thunderstorms, brief but intense rainfall may occur, making it essential for drivers to exercise caution.
“Turn around, don’t drown,” Gass advised, urging commuters to avoid flooded areas. Rainfall totals are expected to range from 0.5 inches in lower elevations to up to 2 inches in higher elevations like the Santa Cruz Mountains. Specific forecasts indicate that San Jose will receive around 0.75 inches, while areas like Oakland, Walnut Creek, and San Francisco are projected to see approximately 0.8 inches of rain.
As this storm progresses, isolated showers began around 5:30 AM today, with the rain expected to taper off by Tuesday afternoon. Gass noted that while this storm is not predicted to cause major flooding, drivers should remain vigilant for possible nuisance flooding and isolated flash flooding conditions.
