New Jersey and Washington, D.C. are experiencing dangerous heat indexes and severe thunderstorms due to the remnants of Beryl, with New Jersey seeing heat indexes up to 108 degrees and a marginal risk of severe weather near the I-95 corridor. More than 1.7 million customers in Texas remain without power as Beryl, which made landfall as a Category 1 hurricane, has caused significant flooding and tornadoes, resulting in at least 10 deaths in Texas and Louisiana. The heatwave extends across multiple states, with advisories and warnings in place, urging residents to stay hydrated and avoid strenuous activities. Cooling centers are being opened in affected areas to mitigate the health risks posed by the extreme heat.
