The primary risks include flash flooding in urban and low-lying areas, as well as along streams and creeks. Minor to moderate river flooding may also occur, potentially impacting adjacent roads and properties. Severe thunderstorms could bring damaging winds strong enough to down trees and power lines, leading to power outages. The highest risk areas include the NYC metro, northeast New Jersey, southwest Connecticut, and the lower Hudson Valley. Residents in these areas should remain vigilant and prepared for rapidly changing conditions.
