A late summer heat wave has gripped much of the United States, with roughly 97 million people facing advisories from the central Plains to the Southeast. Dangerous temperatures and high humidity could cause it to feel up to 115°F in portions of the Southeast due to a trapped heat dome effect. Meteorologists warn that the combination of long-lasting heat, intense conditions, and lack of nighttime relief increases mortality risk.

The Gulf has been warming at twice the rate of other oceans for over a decade, according to a meteorologist with Yale Climate Connections. This warming could lead to stronger storms in the region.

A large, strong, and long-lasting heat dome will cause dangerous temperatures across most of the US Lower 48 states, with temperatures 15–25°F above normal for at least a week. The event threatens health risks, worsens wildfire conditions, and may break over 90 temperature records, including overnight highs. Meteorologists warn that prolonged heat without nighttime relief is particularly hazardous.

A large, long-lasting heat dome will cause dangerously high temperatures across most of the US Lower 48 states, with nighttime heat posing significant health risks and wildfire threats. Meteorologists warn of record-breaking triple-digit highs and prolonged heat exposure affecting millions.
