The Great American State Fair, part of the America 250 celebrations, is temporarily postponed because of extreme heat in Washington, D.C. Organizers announce that the event closes until 5 p.m. on Friday. Attendees are directed to leave the National Mall grounds after a public address announcement informs fair-goers that the fair has been postponed due to the temperatures. CBS News reports that intense heat is shutting down multiple America 250 events, including the Great American State Fair at the National Mall. Deadline similarly says the fair pauses operations, with reopening planned for 5 p.m. The reports describe the closure as a heat-related safety measure affecting scheduled programming and requiring visitors to vacate the grounds, at least temporarily. The coverage is aligned on the cause—extreme temperatures in D.C.—and on the timing of the pause and planned reopening later that day.
