(LiveScience) California forecasters are prepping the state's northern cities for a switch from extreme drought to drenching rain and damaging winds starting tomorrow (Feb. 5).
An incoming atmospheric river could deliver at least 10 inches (25 centimeters) of rain in coastal and inland mountains, and 5 inches (13 cm) in valley areas, according to the National Weather Service. Atmospheric rivers are narrow currents of warm, moist air that transport huge amounts of water vapor from the tropics toward cooler latitudes.
