New York City, NY – A scorching heatwave is set to engulf the United States this week, with up to 265 million people bracing themselves for temperatures exceeding 90 degrees. The National Weather Service has issued alerts for extreme heat in more than 55 million individuals across the nation, and the oppressive conditions are expected to persist through most of the week.

Major cities such as New York City and Pittsburgh are preparing for potentially record-breaking heat waves, with forecasts predicting highs reaching into the high 90s.

In the Northeast, an Excessive Heat Watch has been issued for parts of New England, including Connecticut, Massachusetts, and New Hampshire. In Pittsburgh, temperatures are expected to soar to 99 degrees for a stretch of several days, potentially breaking previous June heat records.

Residents in Washington, D.C., Ohio, and southeast Michigan are also bracing for scorching conditions, with highs consistently approaching the 90s. The National Weather Service has warned of daily temperature records falling in cities like Chicago, Green Bay, and Cleveland as the heatwave intensifies.

Out west, states like Texas, Arizona, Nevada, and New Mexico are facing dangerous heat levels that could hit 110 degrees in some areas. An excessive heat warning has been issued for Phoenix and Tucson in Arizona, prompting authorities to urge residents to stay hydrated and avoid prolonged exposure to the sun.
