NYC Emergency Management(@nycemergencymgt):Wednesday begins one of the most dangerous stretches of extreme heat our city has seen in years, with the heat index potentially into the triple digits by afternoon. And it does not let up, the heat builds day after day into the weekend, and it will barely cool down at night. That is what makes this kind of event so risky. Do not wait. Find a cool option now, any public or private space with air conditioning, like a library, a mall, a friend's place, or a city cooling center. Find one near you at https://t.co/04ULpqxfIY. Check in on older neighbors, relatives, and anyone living without AC. Here is how Wednesday will feel hour by hour, and what to do at each step to stay safe.
