Image From Diana Desrocher Today will be another very hot day. The Roosevelt Island Operating Corp ( RIOC ) has opened an air conditioned cooling center at the Seniors Center. According to RIOC:
The Nation Weather Service has issued a Heat Advisory for New York City from 12:00 noon today until 5:00 PM tonight. A cooling center has been established at the Roosevelt Island Senior Center (546 Main St.) and will remain open from 9:00 AM until 5:00 PM today. As a reminder, a cooling center will be made available when the heat index becomes dangerously high. Individuals without air conditioning, particularly those at risk for heat related illness, should use established cooling centers during a heat wave.
Sincerely,
Roosevelt Island Operating Corp Advisories Group
