Heat dome grips the U.S.: three crucial stats to know
A dangerous heat dome is forming over the Tennessee Valley and will shift to the Mid-Atlantic by week’s end, with NOAA’s HeatRisk projecting about 73 million Americans in triple-digit heat through Sunday, 190 million under extreme humidity by the weekend, and 205 million at major or extreme heat-related risk through Monday; the pattern reflects high-pressure systems and warming climate, and it should ease early next week as another heat dome develops over Western Europe.
