Heat advisory is now in effect from today until Wednesday evening, with hot and humid conditions expected. There is also a high risk of rip currents during this period.

Weather shift brings rain and weekend storms

According to the National Weather Service (NWS), rain is predicted to occur by Friday and Saturday, with a projection of thunderstorms that could be severe.

Network of cooling centers and community guidelines

Across the five boroughs in NYC, hundreds of cooling centres have been opened through Wednesday, providing free air-conditioned spaces to the citizens. Mayor Mamdani informed through an X post that citizens can look for cooling centres near their locations by calling 311 or by utilising the city’s online cooling centre finder.

“NYC, high heat is back. Today, the city will feel like nearly 100 degrees.

This heat wave will not be as long or intense as the last one, but it can still be dangerous without the right precautions.

Stay cool, stay hydrated, and check on your neighbors — especially older adults and people without AC,” Mamdani wrote in the post.
