An Extreme Heat Watch is in effect for the New York City area from Friday evening, July 3, through Saturday evening, July 4. This Watch follows an Extreme Heat Warning, which is active from noon to 9 PM EDT on Friday, July 3. Affected boroughs include Manhattan, the Bronx, Staten Island, Brooklyn, Northern Queens, and Southern Queens.
During the Extreme Heat Warning period, dangerously hot conditions are expected, with heat index values reaching up to around 110 degrees. For the subsequent Extreme Heat Watch period, heat index values up to 105 degrees are possible. This event has the potential to be a multi-day extreme heat event, featuring near record high temperatures and limited overnight relief.
These conditions significantly raise the risk of heat-related illnesses, particularly for individuals engaged in outdoor work or activities. Extreme heat can be deadly for those without adequate cooling and hydration. Seniors, people with chronic health problems, and those with mental health conditions are at an increased risk. Additionally, impacts to transportation infrastructure and electrical and water systems are possible. Homes without air conditioning may experience temperatures much higher than outside.
The combination of high heat and humidity poses a serious health risk. All residents are advised to take precautions to avoid heat exhaustion and heat stroke.
