TUCSON, AZ (Tucson News Now) - The National Weather Service in Tucson has issued a hard freeze warning for this weekend.

The warnings will be from midnight Friday to 9 a.m. Saturday and midnight Saturday to 9 a.m. Sunday.

Most of Pima County, including Tucson, Marana, Vail, Green Valley, Ajo and Sells, will be impacted. These areas should expect low temperatures from 25 to 32 degrees.

Temperatures will begin to drop to the freezing mark after 2 a.m. on Saturday and Sunday with the coldest readings near daybreak.

A hard freeze warning means widespread temperatures at or below 28 degrees are expected with sub-freezing temperatures expected for several hours. These conditions could kill crops and other sensitive vegetation.

To prevent freezing and possible bursting of outdoor water pipes, pipes should be wrapped, drained or allowed to drip slowly.

More tips about protecting people, pets, plants and pipes can be found HERE while an extended forecast is available HERE.

A hard freeze warning has also been issued for Oracle and Mammoth in Pinal County.

The cold weather Thursday forced the closure of the road to Mount Lemmon and left several people stranded in Summerhaven.

According to the NWS Tucson, Summerhaven received between 7 and 10 inches of snow, the most across southeast Arizona.

With even colder temperatures coming, it is doubtful the road will reopen anytime soon.

The status of the Catalina Highway ca change at any time. To get the most up-to-date information, call the Pima County Sheriff’s Department road closure hotline at 520-547-7510.
