Overview
- An NWS flash flood warning covered New York City into the morning and an expanded Flood Watch stayed in effect for parts of the city and northern New Jersey through the evening due to heavy showers and storms.
- Forecasters reported very high rainfall rates, with typical totals of 0.75 to 1.5 inches and isolated spots near 3 inches, raising the risk of quick street and basement flooding.
- New York City Emergency Management pre‑positioned task forces, cleared catch basins in flood‑prone areas, and urged basement residents to move to higher floors and to avoid flooded roads.
- Coastal hazards were also warned, with a High Surf Advisory and elevated rip‑current risk for south‑facing Long Island and beaches where waves were forecast in the 6 to 10 foot range.
- Forecasts call for the immediate heavy‑rain threat to ease by nightfall with a brief improvement followed by renewed storm and humidity chances later in the week, which could produce additional flash‑flood episodes.
