The severe weather poses significant risks to residents in the New York City area and surrounding regions. Flash flooding could disrupt transportation, damage property, and create hazardous conditions, particularly in low-lying areas. Damaging winds may lead to power outages and fallen trees, while hail and tornadoes, though less likely, could cause localised destruction. The areas most at risk include NYC, Central New Jersey, and the Hudson Valley, where the strongest storms are expected to develop.
