Heat advisory, red flag warnings issued
Temperatures in Southern Arizona are again forecast to top 105 degrees on Tuesday, and the National Weather Service has issued a red flag warning, saying that gusting winds and dry conditions create a high fire danger.
In the heat advisory, in effect from 1 p.m. until 6 p.m., NWS said temperatures in the Tucson metro area, and western Pima and south-central Pinal counties are expected to range from 105-108 degrees.
The hot weather played a role in the deaths of two hikers by heat stroke in the past several days, according to the Pima County Sheriff's Department.
In eastern and central Pima County, along with Graham, Greenlee, Santa Cruz and Cochise counties, and southeast Pinal County, NWS warned of high fire danger. A red flag warning of 25 mph winds, gusting to 50 mph, will be in effect from 11 a.m. to 8 p.m. Wednesday.
The red flag area extends west to Sells and Kitt Peak, and north to Red Rock and Oracle.
"Critical fire thresholds are expected to be met by late Wednesday morning," NWS said in the warning.
"Any fires that develop will have the potential for rapid spread. Ongoing fires may experience rapid and erratic fire growth. Outdoor burning is not recommended," NWS said.
The Weather Service warned those who must work or spend time outdoors to take extra precautions. If you can, reschedule strenuous activities to early morning or evening, wear light-weight and loose-fitting clothing, and drink plenty of water to avoid heat exhaustion and heat stroke.
Temperatures in the Phoenix and Casa Grande area and westward to Yuma and the California desert might be even higher. The Weather Service issued an excessive heat watch, warning of temps up to 112 degrees on Tuesday.
