Core Event
Mayor Zohran Mamdani has activated New York City’s Heat and Flash Flood Emergency plans in response to a National Weather Service heat advisory covering Thursday and Friday. The advisory predicts heat-index values near 100 °F, with dew points in the mid-70s and a risk of isolated to scattered thunderstorms that could produce heavy downpours and localized flash flooding.
Background & Context
The advisory, issued at 11 a.m. Thursday, runs until 8 p.m. Friday. Temperatures are expected in the upper 80s to low 90s, about five degrees above normal, with humidity pushing perceived temperatures to the 95-100 °F range. Meteorologists note a Level 1 severe-weather risk west of the city for straight-line winds and a low risk of flash flooding from heavy showers.
Data & Statistics
- Heat-index forecast: near 100 °F on both days; potential peaks in the mid-upper 90s through Tuesday.
- Cooling centers: “hundreds” to be opened across all five boroughs, many pet-friendly.
- COOL vans: 21 vans will conduct street outreach, providing wellness checks, medical care, electrolytes, meals (vegetarian, kosher, halal), sunscreen, and transportation to cooling sites.
- Public facilities: roughly 50 outdoor pools will operate daily from 11 a.m. to 7 p.m.; public beaches will have lifeguards from 10 a.m. to 6 p.m.
- Outreach hours: Code Red outreach runs noon to 8 p.m. Thursday and Friday, targeting homeless residents for shelter and cooling-center referrals.
Official Statements & Responses
Mayor Mamdani urged New Yorkers to stay hydrated, limit outdoor activity during the hottest hours, and use air-conditioned spaces when possible. He emphasized checking on older adults, people with disabilities, and others with chronic health conditions. The Department of Buildings reminded property owners to secure construction sites and equipment ahead of the storms. Residents should call 311 for non-emergency hazards such as downed trees or blocked catch basins, and dial 911 if trapped by rising floodwaters. The mayor also promoted the free Notify NYC text-alert service (text NOTIFYNYC to 692-692) for real-time updates.
