Crews in the south California are scrambling to clear snow-covered roads in the San Bernardino Mountains as at least dozens of residents were stranded Monday as frustration grew with the speed with which access was being restored.

Some local residents have been without power for more than 10 days and are running out of basic supplies after a back-to-back series of snowstorms hit the area.

The mountainous region that surrounds Los Angeles county more than 100 centimeters of snow has fallen in the past few daysas a result of which an unknown number of inhabitants of mountain settlements found themselves in a dead end.

State and local authorities are working to clear embankments of snow using heavy equipment. Officials from the California Department of Forestry and Fire Protection, the Office of Emergency Management, the California Highway Patrol and the California National Guard were called in to assist in the effort.

Crews cleared more than 7.2 million cubic yards of snow from the highway, the equivalent of nearly 2,300 Olympic-sized swimming pools full of snow, ABC reported.

Firefighters used snowmobiles, which are normally reserved for off-road rescues, to respond to emergency calls in residential areas.

“Unfortunately, the snow came off so quickly and accumulated so quickly that the front plows that we were so used to using on a regular basis became ineffective,” San Bernardino County Fire Chief Dan Munsey said at a press conference.

Last Wednesday, Gov. Gavin Newsom declared a state of emergency in San Bernardino County, along with a dozen other counties affected by severe snowstorms.

The San Bernardino Fire Department tweeted: “E3363 located a family in need of diapers and baby food and walked 3/4 mile through the snow to deliver the aid package.

“A total of 165 Crestline residents reached out to make sure gas meters, driveways and vehicles are accessible and clear of snow, medical concerns are addressed and food is distributed.”

A warmer storm system is expected to hit the region Thursday night into Friday morning, likely bringing rain.

Although the warm air and rain may melt the remaining snow at a faster rate, the chance of flooding will increase.

Meanwhile, Northern California, in the Sierra Nevada mountain range, is also seeing record amounts of snow.

Another foot and a half of snow has fallen here in the past day, meaning the area has been buried in 16 feet of powder in the past two weeks.

The snowfall total for this cause is 48.33 feet, rivaling only the winter of 1951-52 for most snow.

However, an avalanche warning is in effect for the Sierra Nevada mountains on Monday, with another storm expected on Tuesday and another for the rest of the week. In total, another five meters of snow is expected.
