Over 80 Million Americans Placed Under Extreme Heat Warnings as Dangerous Heat Dome Expands Across South and Southwest

PUBLISHED Aug 25, 2026, 5:55 AM ET

More than eighty million Americans are currently under extreme heat warnings and advisories as a persistent heat dome expands across the South, Southwest, and Lower Mississippi Valley. The National Weather Service and Weather Prediction Center report that daytime temperatures will reach between one hundred and one hundred ten degrees Fahrenheit in the Southern Plains. Desert regions in Arizona and New Mexico are projected to experience highs soaring from one hundred ten to one hundred fifteen degrees, threatening numerous daily records. Meteorologists warn that unusually warm overnight lows will offer minimal relief, compounding risks for vulnerable populations. The National Weather Service classifies the situation as a major to extreme heat risk, cautioning that prolonged exposure can overwhelm healthcare systems and strain regional power grids. Local authorities have activated cooling centers and urged residents to limit outdoor activities. The hazardous conditions are driven by a strong upper-level high-pressure ridge anchored over the south-central United States.
