US Braces for Another Devastating Atmospheric River Storm.
Another atmospheric river is expected to hit the Bay Area between March 21 and March 23, bringing drenching downpours, high winds, and exacerbating flooding and coastal erosion. This will be California's 12th atmospheric river this winter season, and it is likely to result in more Sierra snow melt and runoff into reservoirs and streams. The wet weather could ease up after March 23, according to the National Weather Service.
