A heat wave described as a “heat dome” is spreading across large parts of the United States ahead of the Fourth of July weekend, with forecasts calling for widespread, potentially life-threatening temperatures. Multiple outlets report that the eastern half of the country is bracing for extreme heat and humidity, including temperatures reaching or exceeding 100 degrees Fahrenheit in many locations. CBS and NBC say more than 100 record-level readings are expected, and NBC reports that more than 200 million people are affected across much of the region. The New York Times and CBS also describe a prolonged stretch of dangerous conditions through the holiday weekend.
Officials and forecasters urge precautions, and NDTV reports health warnings and the opening of cooling centers in parts of the Northeast. Phys.org notes that demand for cooling is straining power grids as many Americans cope with intense heat. CBS adds that the conditions could disrupt or endanger holiday events, including parades and outdoor plans, and that multiple states are forecasting temperatures above 100 degrees over the holiday period.
Travel and public activities are proceeding as normal for the holiday, but planners and residents are advised to take heat-safety measures.
