Freeze warning issued for Sacramento area. How long will frigid weather last?

Bundle up, Sacramento.

The National Weather Service issued a freeze warning for much of Northern California, predicting chilly conditions and areas of frost.

Temperatures in the Sacramento Valley and Sierra Nevada foothills are expected to drop as low as 30 degrees, the weather agency said.

At higher elevations, temperatures could plummet into the single digits.

“These cold temperatures could be hazardous to pets, plants and those without adequate heating,” the weather service said in its warning.

Here’s what you need to know:

When is freeze warning in effect for Northern California?

The freeze warning will remain in effect from 10 p.m. Monday, Nov. 18, to 10 a.m. Tuesday, Nov. 19, according to the National Weather Service said.

After that, “It’s going to warm up a little bit,” said Sara Purdue, National Weather Service meteorologist.

However, she said, temperatures will remain cool as an atmospheric river-fueled storm rolls across the region.

Which areas could see freezing temperatures?

According to the weather service, the freeze warning will affect the entire Sacramento Valley as well as northern San Joaquin Valley and other areas of Northern California.

That includes the cities of Sacramento, Modesto, Stockton, Chico and Redding.

Areas at elevations below 2,000 feet could see low temperatures of 30 to 36 degrees with frost possible in the morning, the weather service said.

Low temperatures could drop to 5 to 15 degrees at elevations above 6,000 feet, according to the weather agency.

How can I prepare for cold weather in Sacramento?

Purdue said you should “make sure your pipes are good to go for cold weather.”

According to the weather service, you can prevent pipes from freezing by letting cold water trickle from the faucet and opening cabinet doors so warm air can circulate around the plumbing.

You should also bring pets and cold-sensitive plants inside, Purdue said.

Ready.gov, a government resource that helps people prepare for emergencies and natural disasters, also has tips on how to brace for the cold:

  • Install and test smoke alarms and carbon monoxide detectors
  • Gather supplies in case of a power outage
  • Do not heat your home with a gas stove or oven as there is a risk of carbon monoxide poisoning

  • Avoid driving in dangerous conditions, if possible, and limit time outdoors.
  • If you need to be outside, wear warm clothes and be aware of frostbite and hypothermia symptoms
  • Keep a full tank of gas

You should also create an emergency supply kit for your home, car and workplace, according to Ready.gov. It should include jumper cables, water, blankets, non-perishable foods and flashlights.
