More than 115 million people across the United States are currently under active extreme heat alerts from the National Weather Service (NWS), according to the National Integrated Health Information System on Saturday.
A heat dome, caused by a high-pressure system that traps warm air near the ground, has settled over the Midwest and Northeast earlier this week, causing record-breaking temperatures in several cities. Arizona's capital Phoenix has already experienced its hottest days of 2024 so far, with temperatures soaring to 115 degrees Fahrenheit (46 degrees Celsius) this week.

The agency also noted that the temperature in Northern California's Sacramento Valley could reach 107 degrees Fahrenheit (41.7 degrees Celsius). This heat wave exacerbates the already challenging wildfire season in California, where dry and windy conditions have sparked several large fires.
