The Los Angeles area is preparing for the tail end of an atmospheric river that will bring "beneficial rain," forecasters say.

The wet weather will bring relief to Southern California after a prolonged period of dryness, but there’s concern that any bursts of heavy rainfall could cause flooding.

Due to the rain expected this week, protective measures including K-rails and sandbags have been placed near hillsides and around homes to keep the debris and mud from causing catastrophic damage to the homes still standing.

After a very dry start to winter, two distinct rainstorms are making their way to the Southern California region.
