San Diego, California - Predictions of snow on Christmas Eve day will have many San Diegans planning trips to the mountain areas around Mt. Laguna, Julian and Palomar Mountain for a chance to see, touch and play in what could be up to 5 to 12 inches at the highest elevations.

The National Weather Service has issued a winter storm warning in effect from 10 p.m. Friday night through 3 a.m. Sunday morning for elevations above 3,500 feet.

The County would like to remind people traveling to the area to be prepared. Prior snowfalls have left drivers in as long as five-hour waits heading into the snowfall area.

Drivers should have a full tank of gas as well as food and water because both road conditions and the sheer volume of traffic can cause significant travel delays in both directions. Also, keep in mind that public restroom facilities are limited in the mountain areas.

Snow chains may also be required by the California Highway Patrol on certain roadways. Chain controls, road condition updates and other safety advisories about County-maintained roads are posted on the Department of Public Work’s Facebook and Twitter sites. However, conditions at any given location may change rapidly and drivers should always be prepared.

The San Diego County Sheriff’s Department reminds people that parking is also limited in the area and parking violations will be enforced and citations issued by both the department and the California Highway Patrol. Vehicles blocking roadways and private property will be towed. Drivers should also take care not to disturb vegetation when parking.

People are also encouraged to pay attention to signs and fences marking private property. Private property is off limits to the public for recreational snow activities. And all visitors should pack out any trash.
