Which door we can’t touch? That’s what the ‘snowball effect’ is all about, says a report

BYLINE: By MARY RICHARDSON and RICHARD E. NELSON Associated PressA snowstorm has swept through southern California and has left much of the state under a foot of snow.

The Los Angeles County Department of Water and Power said Thursday it was working to keep water supply from running out and to clear roads to allow crews to dig through the snow and clear roadways.

But many residents in Southern California have been left without power for more than two days and some homes have been shuttered.

The snowstorm prompted the National Weather Service to issue a snow emergency for the Los Angeles area, including Ventura County, Santa Ana and the San Bernardino Mountains.

The National Weather Services issued a winter weather advisory for parts of the Los Altos Mountains, the San Gabriel Mountains, Los Angeles and Ventura Counties.

It includes areas of central and southern California.

The storm forced a temporary evacuation of about 15,000 residents from the area of the L.A. River that flows through Ventura and Santa Barbara counties, according to the California Department of Forestry and Fire Protection.

A Santa Ana County fire official said the fire department received about 2,000 calls from people stranded on roads, some in wheelchairs and others without power.

A snow storm has swept Southern California and left much in its wake, said a report published Thursday by the nonprofit nonprofit National Climate Assessment Center.

It’s been a storm that has impacted communities throughout the county and across the state, with a huge swath of the Pacific Northwest snowpack having been lost.

It was a significant loss of snow and ice across much of California.

There was some snowfall in the San Joaquin Valley and in the north, but most of the snow was falling in the central and northern Sierra Nevada mountains.
