The primary risks include flash flooding in urban and low-lying areas, particularly in the NYC metro, northeast New Jersey, southwest Connecticut, and the lower Hudson Valley. River flooding could impact adjacent roads and properties near small rivers and creeks. Severe thunderstorms may bring damaging winds, with gusts up to 70 mph, increasing the likelihood of power outages and tree damage. Residents in these areas should remain vigilant, as the combination of heavy rainfall and strong winds could lead to hazardous conditions.
