"Record-Breaking Heatwave Sweeps Across America, Threatening Millions"

Nearly 40 million Americans are expected to experience triple-digit temperatures on Sunday as a dangerous and record-breaking heatwave continues to grip the Southwest. Over 50 million Americans are currently under heat alerts, with nearly 10 million of them facing temperatures of 110 degrees or higher. Heat advisories have been in effect for 19 consecutive days in some parts of South and Southwest Florida. Relief is expected by Sunday as a cold front approaches the northern Gulf Coast, but temperatures will remain hot and closer to average next week. People are advised to take the heat seriously and avoid prolonged outdoor exposure due to the health risks posed by the extreme temperatures.
