The Los Angeles area continues to receive "beneficial rain" as an atmospheric river lingers over the region. Another storm is expected to develop next week.

Forecasters say 'Pineapple Express' storm will probably be beneficial for Los Angeles and Ventura counties, helping to reduce the risk of wildfires.

Two distinct systems will bring widespread light to moderate rain to Southern California: one on Tuesday into Wednesday and another Thursday and Friday.

The upcoming storm is likely to pose a higher risk for mudslides, debris flows and flooding than the rainfall this past week.

A Pineapple Express forms when the jet stream dips south into the tropical Pacific near Hawaii, scooping up warm, moist air and carrying it northeast across the ocean. Named for Hawaii's famous fruit and the storm's origins near the islands, these powerful systems can dump the equivalent of 10 to 15 inches of rain over two to three days.

Two storm systems are bringing rain to Southern California through Friday, but some areas are expected to see less than an inch of rain.

LOS ANGELES (AP) — More rain fell Monday on parts of Southern California after causing mudflows over the weekend, helping firefighters but boosting the risk of toxic ash runoff in areas scorched by Los Angeles-area wildfires.

The gusty atmospheric river storm could cause flooding and rockslides but also will help reduce the risk of wildfires with more dry winds in the forecast.
