New York is waking up to clear skies and sticky air, but it will not stay quiet for long. As of early Tuesday, July 21, 2026, Central Park reported clear conditions with a muggy 73°F and southerly winds around 8 to 12 mph. Forecasters say multiple rounds of heavy showers and thunderstorms are on deck from midmorning through late tonight, and a Flood Watch is in effect for the entire city.
Flood Watch And Timing
The National Weather Service has issued a Flood Watch for all five boroughs from 8 a.m. Tuesday through late tonight, warning that most neighborhoods will likely see 1 to 2 inches of rain, with isolated pockets picking up 3 to 4 inches. Scattered showers are expected to develop after roughly 8 to 9 a.m., with the most intense bands of rain and the highest flash flood risk expected from the afternoon into the evening. Some flooding could begin around noon and generally taper off by about midnight for most areas, according to the National Weather Service.
Storm Impacts
The storms are expected to deliver brief but intense downpours that can quickly overwhelm street drains, along with strong, gusty winds that may knock down branches and trigger scattered power outages. Damaging wind is the main severe threat, though forecasters note a low chance of large hail or an isolated tornado if storms ramp up later in the day. Drivers should be ready for sudden drops in visibility and slower, wetter commutes, especially on surface streets and in neighborhoods with poor drainage.
Beaches, Ferries And Marine
At the oceanfront, a high risk of rip currents is in place through Wednesday, and some offshore waters are under Small Craft Advisories. Swimmers and small boat operators are urged to stay out of the surf. Seas will be choppy, with gusts near 30 to 35 mph on some waters, which could make ferry rides rough and complicate harbor traffic, as noted by the National Weather Service.
City Response And How To Prepare
The city has flood crews on standby and is pre-clearing catch basins ahead of the heaviest rain. NYC Emergency Management has issued a weather alert and says it has activated its flood response plans. For local updates, shelter information and official safety guidance, residents are directed to NYC Emergency Management.
If you live on a flood-prone block, move vehicles off low-lying streets, avoid driving through standing water and plan for extra travel time this afternoon and evening. The situation could escalate if stronger storms develop, and officials say they will issue Flood Warnings or flash flood statements if conditions worsen. Keep your phone nearby for alerts and consider pushing outdoor plans to another day once this soggy system moves out.
