LI Hazardous Weather Outlook: Heat Advisory In Effect Through Tuesday

LONG ISLAND, NY — Hang on, Long Island: The oppressive heat wave is almost over.

According to the National Weather Service, a heat advisory and hazardous weather outlook remains in effect until 8 p.m. for the entire Long Island and New York region.

But there's hope. according to David Radell, meteorologist for the National Weather Service office in Upton. "This is our last day for this hot, humid weather," he said.

While the heat index in the area will make it feel between the upper 90s to the low 100s — from 95 or 98 degrees in areas such as eastern Long Island, and higher, up to about 104 degrees, in the urban areas — temperatures will hover in the low to mid 90s.

"The combination of heat and humidity will make it feel 10 degrees warmer," Radell said.

Tuesday night, however, a cold front is slated to move through the area. "That will cool things off, and the humidity will decrease," he said.

Wednesday's temperatures are expected to reach the mid to upper 80s, with a heat index of about 80 to 90 degrees, "much closer to normal for this time of year," Radell said.

Also, according to the NWS, there continues to be an elevated risk of heat-related illness for

vulnerable populations through early Tuesday evening.

There's an isolated flash flood and severe thunderstorm risk for New York City and points north
and west Tuesday, as well, with a localized risk of flash flooding and severe weather. The localized flash flood risk continues into Wednesday with a marginal risk of excessive rainfall across the entire area, the NWS said.

And for those heading to the beach, there's a high risk of rip currents through 9 p.m. Tuesday.
