Pittsburgh, Pa. – An extreme heat warning is in effect for Allegheny County and much of western Pennsylvania through 8 p.m. Wednesday, as heat index values are expected to climb above 105°F in some areas.
According to the National Weather Service in Pittsburgh, the warning begins at 11 a.m. Sunday and covers counties including Allegheny, Washington, Beaver, and Westmoreland. High temperatures will reach the upper 90s, with a maximum of 97°F expected in downtown Pittsburgh today. Humidity will push the heat index even higher, creating hazardous conditions for anyone outdoors.
The heat advisory and warning area includes major highways like I-376 and I-79, with elevated risks for heat-related illness, particularly for vulnerable groups like children, the elderly, and those without access to air conditioning. Local hospitals are urging residents to limit strenuous activity and stay indoors during peak heat hours.
Cooling centers are expected to open across the region. Residents are encouraged to check with local municipalities for updated locations and hours. Drink water frequently, avoid leaving pets or people in vehicles, and check on neighbors without AC.
This is the first prolonged heat wave of the summer for the Pittsburgh metro. Further advisories may be issued if temperatures remain elevated into late week.
