California could kick off the new year with record low temperatures. The National Weather Service has issued more than 30 winter storm warnings, freeze watches and wind advisories for several regions ahead of a cold front. Areas near the San Gabriel Mountains could see up to a foot of snow, the Los Angeles Times reported, and Rose Parade watchers might experience the event's coldest weather in 52 years.

The temperatures are expected to start dropping Tuesday afternoon, with snow and frost covering locations elevated 2,000 feet or fewer near the Antelope, San Fernando and Santa Clarita valleys. These conditions should continue through Wednesday afternoon, but temperatures in the 20s and 30s will stay through Thursday.

Officials were urging Rose Parade attendees to dress warmly if they plan to camp out along the 5.5-mile route. The annual parade, held in Pasadena on Thursday, typically draws about 700,000 people. It has never been canceled due to a storm, according to the weather service, but it last rained on the parade in 2006.

Meteorologists predicted a low of 32 and a high of 57 degrees on New Year's Day. The lowest Jan. 1 temperature in Pasadena was 32 degrees, a record set in 1952. Parade attendees usually see temperatures between 67 degrees and 47 degrees.

"If anyone's planning on staying outdoors to get a good location at the Rose Parade, they better dress in lot and lots of layers," meteorologist David Sweet told Southern California public radio station KPCC. "Because it's going to be a very cold night."

In preparing for the storm, California officials planned to close areas of the Angeles National Forest at 10 a.m. Tuesday. Expected road closures included Angeles Forest Highway between Aliso Canyon Road and Angeles Crest Highway; Upper Big Tujunga Canyon Road between Angeles Forest Highway and SR-2; and Big Tujunga Canyon Road between Vogel Flats Road and Angeles Forest Highway, the Los Angeles Times reported.

Authorities were warning California residents and visitors who may be accustomed to the state's famously mild weather to bundle up.

“Children, the elderly and people with disabilities or special medical needs are especially vulnerable during such cold snaps. Extra precaution should be taken to ensure they don’t get too cold when they are outside,” Los Angeles County interim health officer Jeffrey Gunzenhauser said in a statement. “There are places where people can go to stay warm, such as shelters or other public facilities."
