EXTREME HEAT WARNING: The National Weather Service in Phoenix has issued an Extreme Heat Warning covering Scottsdale, Paradise Valley, and the broader Phoenix metropolitan area through 8 p.m. Sunday, Aug. 9, with afternoon temperatures forecast between 108 and 114 degrees under dangerously hot and humid conditions.
The NWS characterizes the event as a Major Heat Risk. Heat-related illnesses increase significantly during periods of this severity, the agency said, with overexposure capable of progressing from heat cramps and heat exhaustion to heat stroke without intervention.
The NWS advises rescheduling strenuous outdoor activity to early morning or evening when possible, wearing lightweight and loose-fitting clothing, and drinking plenty of water. For outdoor workers, the agency cites Occupational Safety and Health Administration guidance recommending frequent rest breaks in shaded or air-conditioned environments. Anyone overcome by heat should be moved immediately to a cool, shaded location. Heat stroke is a medical emergency, call 911.
In Maricopa County, free cooling centers, transportation, and water are available. Call 2-1-1 or visit maricopa.gov/heat for locations.
The warning remains in effect until 8 p.m. MST Sunday, Aug. 9.
