The heat wave and storms are expected to impact New York City, North Jersey, the Hudson Valley, and southern Connecticut. Vulnerable populations, including seniors and individuals with chronic health conditions, are at heightened risk of heat-related illnesses. Outdoor workers and those exercising outdoors should take precautions. Heavy rainfall may lead to flash flooding, particularly in areas prone to water accumulation. Residents in basement apartments or flood-prone neighborhoods are advised to prepare for potential water rise.
