The National Weather Service on Thursday issued an Excessive Heat Warning for the upcoming Labor Day Weekend for 11 counties, including Maricopa County and Glendale.
Glendale is expected to hit 112 degrees on Friday, 112 Saturday, and 110 on Monday.
Recommendations include to stay in air-conditioned buildings, limit outdoor activity during the hottest part of the day (mid-day), check on at-risk friends, family, and neighbors at least twice a day, and drink water before, during and after working or exercising outside.
Also, the Arizona Department of Environmental Quality has issued an ozone high pollution advisory for the greater Phoenix area for Friday.
This means forecast weather conditions combined with existing ozone levels are expected to result in local maximum eight-hour ozone concentrations that pose a health risk. Adverse health effects increase as air quality deteriorates.
Ozone is an air contaminant that can cause breathing difficulties for children as well as persons with respiratory problems, according to ADEQ. A decrease in physical activity is recommended.
Residents are urged to carpool, telecommute or use mass transit.
The use of gasoline-powered equipment should be reduced or done late in the day.
