Tuesday was predicted to be the worst day of an uncomfortable heat wave that has swept across most of the country since late last week, with tens of millions of people in major cities throughout the Northeast experiencing record high temperatures. According to the National Weather Service, temperatures in Boston and Washington were expected to rise to 101 degrees Fahrenheit (38 degrees Celsius), breaking existing records by up to 6 degrees. In New York City’s Central Park, the temperature reached 99°F (37°C), surpassing the previous record of 96°F for the area. Other regions of the Eastern United States, such as northern Georgia, the Carolinas, Virginia, Maryland, and Pennsylvania, were also expected to experience extreme heat. US cities hit record highs on hottest day yet, marking a significant peak in this nationwide heat wave.

Impacts on Infrastructure & Public Services

The extreme heat is disrupting public transportation across the Northeast. Amtrak, the U.S. passenger railroad, announced it would reduce train speeds between Washington and New York and between Philadelphia and Harrisburg from 12 p.m. to 8 p.m. on Tuesday, resulting in delays. The National Park Service also reported that the Washington Monument would be closed on Tuesday and Wednesday due to the heat. Construction companies have modified work hours and implemented additional safety measures to protect laborers during these conditions, as US cities hit record highs on the hottest day.
