Flooding and snowfall were reported on some San Diego County roads today, and motorists were ordered to put chains on their tires before venturing into Laguna Mountains.
California Highway Patrol officers said the Carmel Mountain Road connector to northbound Interstate 5 remained closed for a second day today because of flooding.
In the Laguna Mountains, snow fell overnight, enabling people to go sledding, according to employees at Laguna Mountain Lodge at 10678 Sunrise Highway.
CHP officials sent out an advisory at 8:30 a.m. requiring that drivers use chains on their vehicles on Sunrise Highway in the Laguna Mountains.
At Palomar Mountain, about 4 inches of snow fell overnight, said National Weather Service meteorologist Jamie Moker.
The National Weather Service forecast moderate to heavy snow in the mountains today, with 2 to 4 inches below 5,000 feet and 4 to 6 inches above 5,000 feet possible.
A winter weather advisory for the local mountains was scheduled to be in effect until 10 p.m., according to the Weather Service, which said that snow and fog could reduce visibility to a quarter-mile or less.
"Be prepared for slippery roads and limited visibilities, and use caution while driving," the NWS said in an advisory.
