New York City activates heat and flash‑flood emergency plans as extreme heat hits
New York City Mayor Zohran Mamdani has activated the city’s Heat and Flash Flood Emergency plans ahead of a forecasted heat index of around 100 °F and scattered thunderstorms on Thursday and Friday, August 7‑8, 2026. The National Weather Service issued a Heat Advisory covering the period, and the mayor announced the opening of hundreds of cooling centers across the five boroughs, with COOL vans dispatched to check on older adults and other vulnerable residents. Authorities urged New Yorkers to stay hydrated, limit outdoor activity during the hottest hours, seek air‑conditioned spaces, and report non‑emergency hazards to 311 while calling 911 for immediate flood danger.
Other regions across Europe and South America are also experiencing clear skies and warm temperatures on the same day, with forecasts ranging from 3 °C in Necochea, Argentina, to 35 °C in Santa María del Camí, Spain, and no rain expected in most locations.
