Life-Threatening Heat Dome Hits 147 Million Across 28 US States

A severe heat dome is causing record-breaking temperatures and extreme heat warnings across the eastern United States, impacting at least 147 million people in 28 states. Major cities along the Interstate 95 corridor, including New York City, Washington, D.C., and Philadelphia, are experiencing temperatures near or above 100 degrees, with humidity levels pushing heat indices even higher, sometimes feeling like 110 degrees. The heat wave is expected to last several days, with forecasts warning of more than 250 daily temperature records potentially being broken. This heat dome, caused by a high-pressure system trapping heat and humidity, is leading to dangerous conditions including power outages and infrastructure damage such as buckling roads. Public health officials are urging residents to take precautions such as staying hydrated, avoiding prolonged exposure, and using sun protection, as heatwaves remain the deadliest form of extreme weather in the U.S. The National Weather Service has issued its highest level of heat alerts, emphasizing the urgent need for preparedness to mitigate heat-related illnesses and fatalities.
