Americans brave extreme heat at 'once in a lifetime' 250th celebrations

Dangerous heat is throwing a wrench in holiday plans on the eve of the Fourth of July and the nation’s 250th anniversary, but that’s not stopping Americans from flocking to outdoor celebrations.

“It’s hot and loud,” 57-year-old Dale Stevenson of Roanoke, Virginia, said in the nation’s capital on July 3 with a laugh. “But I wasn’t going to miss this weekend. It’s a wonderful opportunity to be here in Washington, DC, for the 250th.”

A heat dome threatening to break records has settled over much of the eastern half of the United States, with the National Weather Service warning that heat indexes due to humidity could reach up to 115 degrees in some places, with widespread temperatures in the 90s to triple digits. 

Though forecasters have warned people to consider canceling their outdoor plans, festivities drew crowds at major cities including Washington, DC, Philadelphia and at Mount Rushmore in South Dakota, where President Donald Trump is expected to speak later in the evening. The weather service said people should drink plenty of water, wear lightweight and light-colored clothing and use air conditioning.

In Philadelphia, a long-awaited Salute to Independence Semiquincentennial Parade was canceled due to heat on the morning of July 3, but the city’s Historic District was still crawling with visitors and performances were underway.

Julian Plotnick, 32, was juggling around Independence Hall with a full July 4 outfit. The celebrations, he told the USA TODAY Network, were a “once in a lifetime opportunity.”

But the heat has led to cancellations and delays in several states. Parades, concerts and fireworks shows were canceled or delayed in Massachusetts, Pennsylvania, Maryland, Virginia and Delaware for July 3 and 4. 

In the nation’s capital, the Great American State Fair on the National Mall was evacuated the afternoon of July 3 as the feels-like temperature hit 111 and attendees took refuge in air conditioned exhibit halls.

Tania Tudor, 46, who traveled to Washington from Austin, Texas, told USA TODAY she planned her trip with her husband for the Fourth of July holiday six months ago. She said Great American State Fair organizers were doing a good job keeping attendees cool by handing out water bottles and providing air conditioning inside tents.

When the fair closed temporarily, many headed to air conditioned museums near the National Mall. Tudor said she’d be back in the evening if the fair reopens, and might come again on July 4.

In New York, Kirsten Williams, decked with binoculars and a water bottle, said she loves ships, and there may never be another event like this in her lifetime. She came from DC to New York to see the Sail4th 250 parade of ships. It reached 98 degrees with a feels-like temperature of 105 the afternoon of July 3 in New York City.

“I either suffer from the heat inside doing normal weekend stuff…or I suffer in the heat with a really, really pretty view,” she said. 

Cynthia Cole, 57, a 4th grade teacher from Manassas, Virginia, told USA TODAY she braved the heat to attend the Great American State Fair to celebrate the Fourth of July. 

She was at the fair for three hours before it closed due to heat. Despite the closure, she enjoyed her visit, she said, pointing to air conditioning inside the fair’s pavilions which made the heat bearable. 

Though she was disappointed the fair temporarily closed, she plans to head back once it reopens, with hopes of seeing the rodeo later today.

“It was worth it just to watch the flyovers,” she said, referring to the nonstop military aircraft overhead and performances from U.S. Air Force Thunderbirds, U.S. Army Golden Knights and U.S. Navy Leap Frogs that took place on July 3.
