Stay up to date with notifications from The IndependentNotifications can be managed in browser preferences.AllNewsSportCultureLifestyle(NWS)A massive, unusually strong and long-lasting heat dome is forecast to bring "significant and dangerous" temperatures 15 to 25 degrees Fahrenheit above normal to as much as two-thirds of the continental United States, starting this weekend and persisting for at least a week.The high-pressure system, initially settling over the Northern Plains, will trap hot air and block cooling winds, leading to record triple-digit highs in states like Nevada, Utah, and Montana, with over 90 U.S. local temperature records expected to be tied or broken by Wednesday.Elevated nighttime temperatures, which impede the body's recovery from scorching days, pose a particular health threat, with meteorologists like Bob Henson warning that heat is as dangerous as tornadoes or hurricanes.While the East Coast may initially be spared, the heat dome is expected to shift and expand, potentially stretching from coast-to-coast, with the Southeast experiencing a peculiar scenario of record-shattering nighttime heat due to added moisture and humidity.Climate scientists confirm that human-caused climate change, driven by the burning of fossil fuels, is a significant factor contributing to the increased intensity, duration, and widespread nature of such heatwaves, making this event at least five times more likely due to climate change in affected areas.In fullHeatwave set to scorch US as meteorologists warn ‘unusually large’ heat dome is ‘not to be played with’More bulletinsThank you for registeringPlease refresh the page or navigate to another page on the site to be automatically logged inPlease refresh your browser to be logged in
