The fourth storm of the week hit Southern California on Thursday, raising flash flooding concerns in the region. Here's the latest on the storm.

Impacts from the incoming storm will hit nearly the entire state of California later this week, only days after flooding rainfall.

Though conditions began to improve on Nov. 16, forecasters warned that another storm system is expected to bring more rain on Nov. 17 and 18.

Widespread rain, mountain snow and flooding risks will threaten parts of Southern California through late week, the last in a long line of storms to drench the state.

A storm is dropping rounds of heavy rain on more than 22 million people across Southern California on Saturday.

The most powerful band of a large atmospheric river storm slammed into Southern California on Saturday, dumping much-needed rain across the region but also bringing mudslide dangers.

In Southern California, the latest atmospheric river shattered daily rainfall records set during a massive 1965 storm. Some major Bay Area cities have also received a substantial amount of rain in November, such as San Jose, Santa Rosa and San Francisco, which received between 4 and 8 inches of rain, according to the National Weather Service.
