A heat advisory is in effect through Tuesday night for oppressively hot weather on Long Island and the entire tristate region.
It was 90 degrees at 4:30 p.m. Monday at Long Island MacArthur Airport, tying the record for the day, which was set in 1977, the National Weather Service said.
"It's like getting hit when you walk outside, and it's going to get worse the next couple of days," News 12 Long Island meteorologist Bruce Avery said, adding that the combination of temperature and humidity made it feel more like 100 degrees at times.
Officials have issued an air quality alert for Long Island and the tristate region until 8 p.m. Tuesday and possibly into Wednesday, and said that elderly and other at-risk residents should consider limiting strenuous outdoor activity.
There is also a chance of rain Tuesday and Wednesday, the National Weather Service said.
Temperatures will continue to reach the upper 80s for the remainder of the week, with the heat index reaching between the mid-90s and 100 degrees on Tuesday and Wednesday, the weather service said.
A heat advisory is issued when a combination of heat and humidity is expected to make it feel like it is 95 to 99 degrees for two or more consecutive days, or 100 to 104 degrees for any length of time.
