Southern California could see record low temperatures on New Year's Day, making for a long, cold night for Rose Parade revelers.
Stuart Seto, a weather specialist with the National Weather Service, told KPCC that overnight temperatures are expected to drop to as low as 32 degrees.
Seto added that the record low temperature for the Rose Parade was 32 degrees in 1952.
"It’s not going to get much warmer that afternoon. The high will be in the upper 50s," Seto said.
Health officials have issued a winter weather warning for the mountains and valleys as an extremely cold winter storm approaches, according to the Associated Press:
The Los Angeles County Public Health department is urging extra precaution for children, the elderly and people who are vulnerable during a cold snap.
The National Weather Service says a cold storm dipping into the region from Canada will bring showers and snow Tuesday afternoon through Wednesday. Snow levels could drop to around the 2,000-foot level.
Forecasters say as much as six inches of snow could fall across interior mountain slopes.
Those who plan to camp out in Pasadena for the Rose Parade are advised to wear layers of clothing.
