Authorities suspect record-setting heat in the deaths of 22 individuals spanning the Deep South to the Midwest and the East Coast. The oppressive temperatures have also led to Fourth of July celebrations being curtailed. The National Weather Service issued heat alerts for nearly 156 million people in the eastern two-thirds of the United States on Saturday.
A high-pressure heat dome settled over the country, causing air to descend and warm, resulting in temperatures exceeding 100 degrees in places such as Washington, D.C., Norfolk, Virginia, and Raleigh, North Carolina.
During Washington, D.C.’s Salute to America 250 celebrations at the National Mall, marking 250 years of independence, emergency workers and the National Guard aided attendees affected by heat-related issues. Visitors to the Great American State Fair in Washington encountered similar conditions.
A man was heard shouting “Emergency! Coming through!” to clear space for a woman on a stretcher. General seating was exposed to intense sunlight, raising chair temperatures to 160 degrees, while pallets of bottled water sat in the sun.
A spokesperson for the joint information center at the National Mall stated that the number of heat-related incidents would be disclosed later. Festivities faced delays when Homeland Security and Emergency Management Agency urged attendees to find immediate shelter due to an impending severe thunderstorm.
Thunderstorms emerged from the collision of warm and cooler air, producing volatile weather from Missouri to Pennsylvania. Federal forecasters indicated severe thunderstorm watches for over 72 million people, with storms capable of generating winds exceeding 65 mph and quarter-sized hail.
Damaging winds impacted Nebraska and Iowa. States from Arkansas to Michigan to New York experienced power outages affecting over 900,000 utility customers on Saturday, reported by PowerOutage.us.
Michigan had the highest number of outages, with over 305,000 affected, followed by New Jersey with 124,000, and Missouri with over 100,000. National Weather Service forecasts predict that cooler northern air will soon move the heat dome south and west, which should relieve extreme temperatures in the Northeast.
However, they cautioned about the ongoing risks of warm temperatures and high humidity during overnight hours, exacerbating heat-related impacts.
New Jersey authorities suspect heat has caused the deaths of 19 individuals this week, primarily in central and northern areas, starting Thursday, according to state health commissioner Dr. Raynard Washington.
“Unfortunately, many were found in homes without air conditioning,” Dr. Washington stated at a news conference with Governor Mikie Sherrill on Saturday. “A few died outside, some on the streets, others in parked cars.”
State officials are sending resources like chillers and generators to healthcare facilities strained by the heat. “In necessary cases, we’re evacuating patients from impacted facilities,” Washington affirmed.
Cook County, Illinois reported a heat-related death, with the cause attributed to organic cardiovascular disease worsened by heat stress, according to government spokesperson Natalia Derevyanny.
In Hinds County, Mississippi, 74-year-old Mitchell Ray Cooley died from heat exposure on Thursday, say state officials. Cooley was subject to a Silver Alert bulletin by the Mississippi Bureau of Investigation after being reported missing. His body was discovered near a gas station, the county coroner announced, explaining, “Mr. Cooley suffered from a medical condition impairing his judgment.”
Martha Irene Van Egmond, age 83, passed away in Bolton, a town approximately 200 miles north of New Orleans, on June 27. Hinds County’s chief death investigator, Jeramiah Howard, also attributed her death to the heat.
