San Bernardino County firefighters on Wednesday morning, Dec. 24, were rescuing motorists and residents in the Wrightwood area who were cut off by mudflows and fast-moving water that made Highway 2 impassable.
There were no immediate reports of injuries requiring hospitalization, said Chris Prater, a Fire Department spokesman.
It was unclear how many people were affected or whether they were in any immediate danger. The slides across roads and Highway 2 stopped drivers in their tracks. And residents in Wrightwood called 911 to report that they could not get out of their homes, Prater said.
Highway 2 was closed from 3.3 miles east of Newcomb’s Ranch to Highway 138 in San Bernardino County, the Caltrans website said.
The incident commander requested four-wheel-drive fire engines, swift-water rescue crews, bulldozers, hand crews and urban search-and-rescue teams, Prater said.
The San Bernardino County Sheriff’s Department issued an evacuation warning for the area and posted a map of evacuation advisories on its website.

Prater encouraged travelers and residents not to drive through moving water and to sign up for alerts at the website prepare.sbcounty.gov.
Moderate to heavy rain will increase the risk of flash flooding and localized flooding, the National Weather Service said. Heavy rain is expected to decrease in intensity on Wednesday night, leaving scattered showers on Christmas Day before a new band of showers arrives, producing rain Thursday night into Friday.
Gov. Gavin Newsom on Wednesday declared a state of emergency in San Bernardino, Riverside, Orange and Los Angeles counties because of the storm, which is expected to last several days. The action allows state resources to be mobilized and authorizes Caltrans to seek federal assistance for repairs to damaged roads and highways.
