New York City has activated its emergency heat and flash-flood plans in anticipation of several days of extreme heat and humidity, which are expected to make the city feel like a Caribbean island. A heat advisory is in effect for all five boroughs from Thursday morning through Saturday evening.
Forecasters predict that the combination of high temperatures, with daytime highs near 90 degrees Fahrenheit, and intense humidity will push real-feel temperatures above 100 degrees Fahrenheit at times during the afternoon. This oppressive moisture also creates conditions for scattered heavy downpours and thunderstorms, particularly late Friday, with a chance of showers persisting into Saturday afternoon. Rainfall rates in some storms could exceed two inches per hour, raising concerns about flash flooding in low-lying areas and those with poor drainage.
Mayor Zohran Mamdani announced the activation of the emergency plans on Wednesday, emphasizing preparedness and community support. "High heat and severe storms are rolling into New York City, and the best thing we can do right now is prepare and look out for one another," Mamdani stated. The city is opening hundreds of cooling centers across the boroughs and activating a "Code Red" from noon to 8 p.m. on Thursday and Friday to expand street outreach to homeless New Yorkers, connecting them with shelter and cooling facilities.
City officials are mobilizing resources, including clearing catch basins and preparing emergency crews. The mayor urged residents without air conditioning to utilize cooling centers and advised those in flood-prone areas to have evacuation plans. He also encouraged checking on neighbors who might need assistance.
Relief from the tropical conditions is anticipated by Sunday, with a mostly dry day expected and a slight decrease in humidity. However, residents are advised to stay hydrated and limit outdoor activities during the hottest parts of the day until the weather pattern shifts.
