Conditions are expected to improve significantly Wednesday night, with drier air and partly sunny skies forecast for Thursday. Highs will be in the lower 80s — well below the dangerous heat levels of last week.

Avoid underpasses, low-lying roadways, and areas with poor drainage. Never drive through flooded roads — turn around, don't drown. Residents in basement and ground-floor apartments prone to flooding should be prepared to evacuate if conditions worsen.

New Jersey Transit has suspended service in both directions during peak storm periods. Subway disruptions are also possible.

Over 630 flights have been cancelled or delayed at JFK, LaGuardia, and Newark airports as of Tuesday morning, with LaGuardia the hardest hit. Contact your airline directly to rebook.

Rainfall rates of 1 to 2 inches per hour are possible during the strongest storms — enough to rapidly overwhelm urban drainage systems. Those most at risk of flooding include North and Central New Jersey, Metro New York City, Long Island, and coastal Connecticut.

A Flash Flood Watch is in effect for NYC and northeastern New Jersey through Tuesday night. Rainfall totals of 2 to 4 inches are expected citywide, with isolated higher amounts possible.

The primary threats include damaging wind gusts up to 65-75 mph capable of downing trees and power lines, large hail, flash flooding, and isolated tornadoes. The greatest tornado and straight-line wind risk is concentrated in the Poconos, Catskills, and New Jersey, though dangerous storms could extend into all of New York City.

The National Weather Service (NWS) Storm Prediction Center has placed the tri-state area at a Level 3 of 5 Enhanced Risk for severe weather — the same level that prompted significant damage during last week's storms.

Periods of rain are expected to begin as early as Tuesday morning, with moderate to locally heavy rain becoming increasingly likely after 4 p.m. Multiple rounds of thunderstorms are most likely between 4 p.m. and 11 p.m. Showers may linger into Wednesday morning.

NYC Emergency Management (NYCEM) issued a weather alert Monday evening and activated the city's Flash Flood Emergency Plan ahead of severe thunderstorms expected Tuesday afternoon and evening.
