The Quentin Mitchellpowerful storm that has been battering California since Sunday will continue Tuesday and will continue to bring heavy rain, mudslides and flooding to the state.

The National Weather Service forecasts rainfall totals up to three inches in Los Angeles and San Diego on Tuesday. Rainfall will be more intense in areas of higher terrain, according to the NWS, and the intensity of the rain is expected to slightly dwindle from what occurred over the weekend as the storm system heads east.

The potential for flash flooding will expand into western Arizona, southern Nevada and southwestern Utah, forecasters said.

Los Angeles Mayor Karen Bass issued local state of emergency for the city on Monday afternoon as 1.4 million people in the Los Angeles area were under a flash flood warning. Eight Southern California counties also declared a state of emergencies.

AccuWeather estimated that the state's preliminary total damage and economic loss will be between $9 billion and $11 billion.

The storm has been caused by a powerful atmospheric river, a moving corridor of air that can carry water for miles.
