A few days of temperatures in the 80s this week will give way to rain, snow, high winds and falling temperatures Thursday as a winter storm system moves into Southern California.
There will be widespread showers throughout the day, with heavier rains expected to hit the Los Angeles-area by 2 p.m. At 10 a.m., radar showed a band of showers stretching from Rancho Palos Verdes to the San Fernando Valley.
There is a possibility of isolated thunderstorms as well as hail.
The National Weather Service has issued a Winter Weather Advisory through 4 a.m. Friday. Wind chill temperatures are expected to drop below freezing in the LA County Mountains and Antelope Valley Thursday and Friday.
Snow and gusty winds are expected in the mountain areas of San Bernardino County, Riverside County, and San Diego County, with gusts up to 50 mph, reaching up to 60 mph near mountain ridge tops, according to the National Weather Service.
Between 2 and 5 inches of snow is expected in areas above 4,500 feet. Snow levels could drop to as lows as 3,500 feet by Thursday evening.
The weather could create hazardous driving conditions – including slippery roads and limited visibility on the 5 Freeway near the Grapevine, Hwy 33, and Hwy 2. The National Weather Service urges travelers to use caution while driving.
The Department of Public Health has issued the following tips for cold weather protection:
- Dress in layers of warm clothing if you plan to be outdoors.
- Protect extremities from the cold by wearing a hat, scarf, gloves, and socks.
- Offer to help those in your neighborhood with limited access to heat, such as seniors or those who are ill. Check on them frequently.
- During peak cold times, if you don't have a heater in your home, visit indoor public facilities such as shopping malls, libraries or senior centers.
- If you have pets, bring them indoors and do not leave them outside overnight.
- If you use an outdoor generator at home, place it at least 10 feet away from all doors and windows to avoid exhaust gases entering the home.
- Stoves, barbeques and ovens can produce a deadly gas known as carbon monoxide when used to heat a home. Never use these appliances in place of approved heaters such as electric, natural gas, or fireplaces.
- Install a carbon monoxide detector in your home to reduce the risk of poisoning.
