The severe weather poses risks to millions across the affected regions. Damaging winds and hail could lead to property damage, downed trees, and power outages. Heat index values in the triple digits increase the risk of heat-related illnesses, particularly for vulnerable populations such as the elderly and those without air conditioning. Thursday's storms already caused significant disruptions, including power outages and wind damage in areas like New York's Southern Tier, Pennsylvania, and Maryland. The densely populated Interstate 95 corridor is particularly at risk as storms move eastward.
