The severe weather could impact residents across New York City and New Jersey, with risks including property damage, power outages, and hazardous travel conditions. High winds may cause tree damage and downed power lines, while localized flooding could occur on roads due to heavy rainfall. The heat index exceeding 100°F (38°C) poses a health risk, particularly for vulnerable populations such as the elderly and those without air conditioning. Additionally, the possibility of isolated tornadoes adds a layer of unpredictability and danger to the forecast.
