More than 77 million Americans were on heat alert to start the weekend as record temperatures turned deadly in Pennsylvania and altered the 2022 New York triathlon.
An excessive heat warning is in place through Sunday evening in parts of New Jersey, Delaware and Pennsylvania, including Philadelphia, which is expected to reach a heat index of 107 degrees on Saturday.
National Weather Service forecasters say extreme heat and humidity will significantly increase the risk of heat-related illnesses, including heatstroke.
On Saturday, Pennsylvania state officials said a 73-year-old Allentown man died, in part due to heat exposure.
Excessive heat in Pennsylvania turned deadly early this weekend after officials said a 77-year-old man died of heat-related causes. An excessive heat warning is in place for parts of Pennsylvania, New Jersey and Delaware through Sunday evening.
Philadelphia libraries are open as cooling centers to relieve residents without air conditioning. SEPTA, the metro’s bus system, has parked buses throughout the city to also serve as cooling hubs.

Boston officials announced on Friday that the Boston Triathlon 2022 will be moved from Sunday July 24 to August 21 in an attempt to avoid the heat.
The 2022 New York Triathlon is still set to continue on Sunday as the heat index is expected to reach 104 degrees along parts of the event. However, the organizers also decided to shorten parts of the event due to the dangerous heat.
The triathlon bike will be reduced from 40 km (24.8 miles) to 20 km (12.4 miles) and the race reduced from 6.2 miles to 2.5 miles.
“While it is disappointing to reduce the duration of both races, our number one priority is to do everything we can to ensure the safety and well-being of our competitors, volunteers, medical staff and spectators,” said triathlon officials.
On Saturday, temperatures will be in the 90s, with heat index values ranging from 95 to 100 in northern Connecticut, western and eastern Massachusetts, and Rhode Island. On Sunday, the heat index will jump to triple digits in Boston, New York and Washington.
In the northeast, the overnight hours will not offer much relief from the hot and humid conditions, with overnight temperatures remaining in the upper 70s through Sunday.
Visitors and residents of the nation’s capital will also want to stay hydrated throughout the weekend, with high temperatures forecast in the 90s and a possible high of 100 degrees on Sunday, about 10 degrees above average.
Heat advisories are also sweeping across the Midwest and Central United States, including Wichita, St. Louis, Des Moines and dipping south into Shreveport, Louisiana and Birmingham. Again on Friday, highs will be in the mid-90s to low 100s with widespread Heat Index readings above 100.
In the desert southwest, it’s hot even by their high standards. Excessive heat warnings have been issued for areas such as Phoenix and Las Vegas.
Temperatures for much of the desert southwest are expected to reach over 100 degrees Saturday, including 110 in Las Vegas.
As these temperatures continue to soar, it is imperative to take the necessary precautions to stay cool and safe.

First, try to limit the time spent outside in excessive heat. The best time to be outdoors would be early morning or late evening.
If you must go out during the day, wear loose, lightweight, light-colored clothing and drink plenty of fluids.
“Always look before you lock” to make sure you haven’t left children or pets inside a car. Temperatures inside a locked vehicle with the windows up can be deadly.
