The latest powerful storm to hit Southern California brought new mudflows and hazardous driving conditions to local mountain communities over the weekend.
Wrightwood, in the San Gabriel Mountains, was still cleaning up from a destructive Christmas storm when the most recent round of rain triggered additional debris flows. The earlier storm damaged homes and buried cars up to their windows in mud.
Video recorded Sunday showed fast-moving mud and debris rushing near homes and making nearby highways and roads impassable.

KTLA’s Erin Myers was headed to Wrightwood to survey the damage Monday morning but was forced to take an alternate route because of flood damage.
In the nearby San Bernardino Mountains, heavy rain likely contributed to multiple crashes, including one vehicle that landed in a creek after going over the side of Highway 18 in the Arrowbear area of Running Springs Sunday.

Caltrans reported no current restrictions on Highway 18 as of Monday morning.
Much of the flooding was due to the warm nature of the storm. Snow fell only at the highest elevations, but a mix of rain and snow was captured at Green Valley Lake.
The weather is expected to give mountain communities a chance to recover as drier conditions are forecast this week, with sunny skies returning by Thursday and continuing through the weekend.
