First freeze warning of the year issued for northern Utah

SALT LAKE CITY — The first winter freeze of the season is expected to hit parts of the Wasatch Front Monday night into Tuesday morning, prompting a Freeze Warning from the National Weather Service in Salt Lake.

🥶 A Freeze Warning is in effect tonight into Tuesday morning for Eastern Box Elder County and portions of the Northern Wasatch Front as temperatures drop near to below freezing overnight. Take action now to protect sensitive plants, people, pets, and pipes! #utwxpic.twitter.com/wEX2yRqCOy — NWS Salt Lake City (@NWSSaltLakeCity) October 20, 2025

Temperatures are forecast to drop to or below 32 degrees in areas along the Northern Wasatch Front, including Davis, Weber and Box Elder Counties. The cold snap could damage or kill crops and plants, and may even crack exposed pipes. At J&J Nursery and Garden Center in Layton, staff are already preparing for the drop in temperatures.  Staff demonstrates to KSL TV how folks can use freeze blankets to protect vulnerable plants. “If you want to get the stuff out of the ground, get it out of the ground,” said Josh Mace, the nursery manager, noting that tomatoes, peppers and other sensitive crops are at risk. "Some perennials may survive the freeze, but annual flowers likely won’t make it through the night," he said. Seth Warthen, a lead meteorologist at the National Weather Service Forecast Office in Salt Lake City, said this is the first freeze of the year for many outlying areas.“It pretty much ends the growing season,” Warthen said. “It’s to give people the notification if they haven’t winterized sprinklers or anything like that yet, if they still have a garden growing, that it might be time to take steps to prepare for those freezing temperatures.” For those without frost blankets, bed sheets can be a good alternative to cover plants, said Mace.  And when winterizing your sprinkler system, don’t forget to disconnect your garden hose.
