"Record-Breaking Heat Wave Puts 100 Million Under Advisories"

A persistent heat dome is causing record-breaking temperatures across the eastern U.S., with highs reaching into the triple digits and heat indices soaring even higher. The extreme heat is affecting millions, leading to heat advisories, suspected heat-related deaths, and increased emergency room visits. The Midwest, mid-Atlantic, and parts of California are particularly impacted, with some areas experiencing temperatures over 100 degrees. Relief is expected in some regions by late weekend with the arrival of a cold front and thunderstorms.
