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.

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

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.
