By mid-August, extreme heat and high humidity returned to Alabama. On August 11, the National Weather Service in Birmingham issued a Heat Advisory for August 12, with heat index values projected between 101 and 107 degrees in counties such as Tuscaloosa, Lamar, and Pickens. The Alabama Department of Public Health issued warnings regarding heat-related illnesses, including heat exhaustion and heat stroke, noting that heat stroke is a medical emergency that can cause body temperatures to rise to 106 degrees or higher within minutes. As the heat wave intensified, the National Weather Service issued advisories for much of the state, forecasting rising temperatures from August 14 through August 17. High temperatures were expected to reach triple digits in areas including Demopolis, Fayette, Huntsville, Jasper, and Tuscaloosa. Heat indices were projected to spike, with some areas potentially reaching 113 degrees. By August 16, the National Weather Service in Birmingham upgraded the situation, issuing an extreme heat warning in effect through 9 p.m. on Monday, August 17, warning that such long-duration heat with little overnight relief can be deadly. In response, the City of Birmingham activated multiple cooling stations across every quadrant of the city, including library branches and community organizations like Faith Chapel Care Center and One Roof. As of August 19, heat advisories remained in effect for parts of Alabama and the North Escambia area, with heat indices potentially climbing above 105 to 110 degrees. By late August, the National Weather Service in Birmingham warned of “dangerous heat” throughout the week, with West Alabama expected to experience “feels-like” temperatures between 99 and 104 degrees. In early September, hot and humid conditions persisted in Alabama, with heat indices projected to range between 105 and 109 degrees through the end of the week.
