Heat Wave Expands, Triggers Health and Safety Warnings

A prolonged heat wave is impacting much of the Southeastern United States, with millions under advisories or warnings across Florida, South Carolina, Georgia, and Alabama. Heat index values are frequently reaching 105–110 degrees Fahrenheit, and some areas, including the Florida Panhandle and parts of South Carolina, are experiencing indices as high as 115. Authorities are urging residents to stay indoors, stay hydrated, avoid strenuous outdoor activities, and check on vulnerable populations due to significant heat illness risks. Limited relief is expected from isolated afternoon thunderstorms, but temperatures are unlikely to drop substantially before the weekend. Meanwhile, the Northeast and Midwest are temporarily spared from the heat but are facing flooding and air quality concerns caused by heavy rain and wildfire smoke. The ongoing heat is worsening drought conditions in South Florida, with officials also highlighting the need to protect pets and practice heat safety.
