The severe weather poses risks to a vast area from the Midwest to the Northeast, with urban centers like New York City, Boston, and Philadelphia particularly vulnerable. Damaging winds capable of toppling trees, hail, and tornadoes are expected, with the highest tornado risk spanning western New York to eastern Pennsylvania. Flash flooding is a major concern, especially in urban areas, where heavy rain could disrupt commutes and inundate infrastructure. Saturated ground from prior storms increases the likelihood of significant flooding, potentially leading to road closures and property damage.
