Portions of Arizona face a freeze warning for early Friday morning, as temperatures are expected to plunge into the 20s.

Communities across the state are confronted with heightened risks to agriculture, infrastructure and possibly public safety following the National Weather Service’s (NWS) issuance of a freeze warning, with some regions expected to see temperatures dip as low as the mid-20s.

The alert highlights the potential threat to crops, sensitive vegetation and plumbing, with urgency for protective actions spanning from homeowners to utilities and farmers. The warning comes as a broader weather system impacts the Western United States, with millions urged to take precautions amid a winter storm warning.

According to the NWS, the freeze warning affects eastern Cochise County below 5,000 feet, the upper Gila River Valley, upper San Pedro River Valley, upper Santa Cruz River Valley, Altar Valley, Globe, Miami, San Carlos and the Tonto Basin.

The warning goes into effect from 2 a.m. to 9 a.m. Friday MT. Temperatures from 29 to 32 degrees are expected in the upper Gila River valley, upper Santa Cruz River Valley and Altar Valley, the NWS says. Temperatures from 25 to 29 degrees are expected in the upper San Pedro Valley and Sulphur Springs Valley.

For Globe, Miami, San Carlos and the Tonto Basin, the NWS expects temperatures in the low 30s. Below is a map of the affected region:

"Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing," the NWS warns.

On X Wednesday, the NWS Tucson said, "A colder airmass taking-up residence the next few days across Southeast Arizona. Afternoon highs 5 degrees below normal today & FRI. Morning lows will be chilly, especially the valleys S&E of #Tucson. For some of these areas, it will be the first freeze of the season. #azwx"

NWS Meteorologist Brian Hurley told Newsweek via phone Thursday night that Arizona "certainly can" see temperatures this low, as some areas are "10 degrees below average."

"The highs are expected to be near 60 tomorrow, for areas under the freeze warning," Hurley added. "A lot of the coldest air is near the middle part of the country and east."

Elsewhere in nearby regions, alerts extend into Idaho, Montana, Utah and Wyoming, with some Colorado areas forecast to see snow accumulations of 12 to 24 inches and gusting winds up to 55 mph, the NWS says.
