Millions Face Extreme Heat Danger

A prolonged and dangerous heat wave is set to intensify across much of the central and eastern United States, continuing through the Fourth of July weekend. Searing high temperatures combined with suffocating humidity could approach all-time records in the mid-Atlantic region. Approximately 230 million people, roughly two-thirds of the U.S. population, are expected to be exposed to extreme heat this week.

The National Weather Service forecasts the extreme heat to peak from Tuesday, June 30, through Thursday, July 2, in the Midwest and Mississippi Valley, before shifting eastward. Highs in the 90s are anticipated as far north as Michigan and Wisconsin, with heat indices reaching triple digits in major cities. The mid-Atlantic could experience dangerous heat indices of 100 to 110 degrees, with possible multi-day triple-digit temperatures.

Record energy usage is predicted for mid-Atlantic power providers, particularly on Thursday, July 2, raising concerns about potential power outages to stabilize the grid. Meanwhile, a tropical system off the Southeast coast is expected to be weakened by the heat dome, posing no significant threat for the holiday weekend. Experts are urging the public to take precautions, stay hydrated, seek shade, and check on vulnerable individuals.
