A winter storm dumped massive amounts of precipitation across southern California this weekend, including almost two metres of snow to Mountain High and more than 12cm of rain to Cucamonga Canyon.
The hefty snowfall totals included 1.5 metres to Snow Valley, 1.4 metres to Bear Mountain Snow Summit, 1.3 to 1.4 metres to Wrightwood Acorn Canyon, 1.1 metres to Green Valley Lake, 1 metre to Mount Baldy, and 90cm to Lake Arrowhead, according to the National Weather Service in San Diego.
The precipitation came as a rare blizzard warning was in effect for parts of southern California and the Los Angeles region, spawning unfamiliar wintry conditions at higher elevations.
In addition, heavy rainfall brought several inches of rain to the area, including more than 10cm in Holy Jim Canyon, Lower Silverado Canyon and Henshaw Dam; more than 7.7cm in La Jolla Amago, Costa Mesa, Mount Woodson and Carlsbad Airport; and more than 5cm to John Wayne Airport, Escondido, San Bernardino and Temecula, according to the service's five-day rainfall reports.
The storm made for dangerous travel conditions in some areas.
In Los Padres National Forest, State Route 33 was closed due to rock slides and erosion from this and previous storms, according to video from the California Department of Transportation.
Lynda Sandoval and her husband, who live in Frazier Park, about 105km north-west of LA, have been unable to leave their home since Friday, Sandoval told CNN.
Heavy snow created dangerous driving conditions in the area and officials have closed sections of Interstate 5.
She told CNN she prepared for the snowstorm and has enough food to last her a few days but is shocked by how much snow has fallen in the area.
"I never have seen this much snow living up here. Neighbours that have been here longer than us said the last snow related to this was back in 2011 but not this severe," Sandoval said.
"It took over four hours to get our truck out yesterday and all our neighbours are shovelling snow whenever there is a break.
"The community up here is amazing with neighbours helping neighbours during this time.
"They're sharing groceries and shovelling snow in driveways."
The same storm system is moving east and was expected to produce a significant damaging wind event across the central US on Sunday.
More than 20 million people are under the threat of severe storms Sunday from western Texas to Illinois, including Oklahoma City, Tulsa, Kansas City, Fort Worth, and St Louis.

Meanwhile, a new winter storm is set to bring more rain and snow to the western US, starting with the Pacific Northwest on Sunday.
More than 30cm of snow is possible with the system across the Sierras and Cascades.
A second system will be right on the first's heels, pushing inland across the Pacific Northwest tonight bringing even more snow.
An additional 30cm to 60cm of snow is possible across the Cascades, Sierras, and Rockies through Tuesday.
Isolated areas of the Sierras could see up to 90cm.
The snowstorms will create dangerous or impossible travel conditions across the western mountain ranges through the beginning of this week.
