US Heat Wave: Latest Forecast for the East Coast

A relentless and intensifying heat wave will continue to expand across the central and eastern United States on Tuesday, bringing well-above-average heat to millions of people from the Midwest to the East Coast and prompting health advisories across several states.

On Monday, dozens of towns across the Mid-Atlantic and the Northeast set or tied records for the hottest recorded temperature for the date, and dozens more could fall on Tuesday, according to the National Weather Service. Baltimore, Washington, Philadelphia and other cities on the East Coast could see 100 degrees or higher on Tuesday.

“This is the deadliest weather threat we face in New York City — treat it that way,” the city’s Emergency Management said on social media. “Don’t wait until you feel sick. Heat builds. It compounds. It kills quietly.”

New York City officials noted that more than 500 residents die prematurely each year from heat-related causes, and they expect oppressive temperatures to persist through at least Tuesday.

In Philadelphia, the Department of Public Health issued a heat health emergency, which began at noon on Sunday and will continue through Wednesday evening.

Residents were advised to check on neighbors, family members and pets, and to be aware of heat-related illnesses such as dehydration, heat exhaustion and heatstroke.
