The cold snap that has brought unseasonably cold temperatures to California has engulfed several other Western states.
The National Weather Service has told residents in most of southern Arizona, including Tucson, to prepare for near-record cold Sunday morning. The NWS has issued a hard-freeze warning for the area effective late Saturday night until Tuesday morning.
Overnight temperatures could fall to the single digits in some areas. The NWS said the temperatures are expected to dip low enough to kill some vegetation and crops while creating dangerous conditions for residents and pets. Exposed water pipes will freeze, the agency said.
A freeze warning is also in effect until Tuesday morning for the greater Phoenix area with morning lows in the low 30s for the city, while outlying suburbs and rural areas should expect temperatures to dip into the low 20s.
