![Record-Breaking Heat Wave to Impact 260 Million People in the US: Temperatures Expected to Reach Over 100°F for Several Weeks](https://images.axios.com/20ylPbSAPYi2gTqIl8j5gunCPV8=/0x0:1920x1080/1366x768/2024/06/14/1718374789718.png)
A record-breaking and prolonged heat wave is set to impact millions of people in the US, starting from Sunday. Temperatures are expected to reach or exceed 90¹F for over 260 million people, with many experiencing temperatures at or above 100¹F. The heat wave is anticipated to last for several weeks and will affect major cities such as Chicago, Washington, D.C., and New York City. Alongside the extreme heat, an expansive and powerful heat dome will build over the East starting Sunday, bringing significant heat waves to the Midwest and Great Lakes. Simultaneously, the Atlantic hurricane season looks ready to awaken with a medium chance a tropical depression could form in the Bay of Campeche by midweek. The first heat wave of the summer is coming to the Eastern United States next week, and is likely to come as a shock to human bodies that have not adapted to summer swelter. Temperatures will feel warmer than the forecast calls for, making it feel over 100 degrees at times. The heat wave will be widespread across the entire eastern half of the United States, with temperatures struggling to fall below 70 degrees when the sun goes down, providing little overnight relief. High temperatures could challenge records on Wednesday, Thursday, and Friday during this heat wave. There is potential for triple digit heat index during this period. The first heat wave of the season can come as a shock to the human body, which has not entirely adapted to summer swelter.}
