More rain to fall in Northern California on Thursday morning

More rain is forecast to fall Thursday morning in Northern, Central and Southwestern California, with highs in the mid-70s, the National Weather Service said.

Forecasters say thunderstorms are possible in parts of the Central Valley and the San Joaquin Valley.

Heavy rainfall could cause flash flooding, and mudslides could occur, the weather service said.

Rainfall totals could reach up to 8 inches in some areas, the agency said.

The weather service warned the region is still at risk of heavy rain and wind gusts of more than 70 mph, with winds gusts up to 75 mph.

Forecaster Sean O’Sullivan said the weather system is moving northeast at about 17 mph, which would make it one of the most severe weather systems ever recorded in California.

It will likely last from a couple of hours to a couple days, the forecaster said.

More to come.
