Heat Wave and Storms Impact Millions Across the U.S.

A persistent heat wave continues to affect the East Coast, Southeast, and Southwest, with officials reporting at least 25 fatalities linked to the extreme temperatures. According to the latest data, 40 million people are under heat alerts. The week has seen temperatures soar, with July Fourth marking at least 18 record highs in cities like Washington, D.C., Baltimore, and Raleigh. As celebrations persisted in Washington, D.C., visitors were seen shielding themselves from intense sun exposure.

By Sunday evening, heat index values were projected to reach between 100 to 105 degrees in areas such as Philadelphia, Washington, Baltimore, Raleigh, Charleston, and Jacksonville. These values indicate what the temperature feels like to the human body. However, relief is anticipated this week, with temperatures likely to dip to highs of 70s to low 90s along the East Coast.

Meanwhile, extreme heat watches are in effect for the Southwest, particularly in parts of Arizona and California, including cities like Phoenix and Tucson, from Tuesday to Thursday. Daytime highs in these areas could peak at a sweltering 114 degrees.

The heat wave has reportedly resulted in 25 deaths, with the majority occurring in New Jersey. The New Jersey Department of Health has reported 22 deaths across 10 counties. Additionally, two deaths have been confirmed in Hinds County, Mississippi, and one in Cook County, Illinois.

New York City health officials reveal that more than 378 people have sought emergency medical care for heat-related illnesses.
