Wider weather episode
A very strong area of low pressure, tapped into an atmospheric river driving up subtropical moisture, produced substantial rainfall across southern California. This led to some areas within the San Bernardino mountains receiving well over a foot of total rain on Christmas Eve, and resulted in significant flooding for the city of Wrightwood. There also road closures due to debris flow along Highway 2.
