Overview
- Emergency crews and utilities are responding to localized flooding, downed trees and power outages that hit during Monday morning's peak threat window roughly 4–10 a.m.
- The National Weather Service has a Flood Watch in effect through 6 a.m. Tuesday and the NOAA Weather Prediction Center placed the region at a Level 3 flash‑flood risk.
- Forecasters expect a baseline of about 2 to 3 inches of rain across much of the city with isolated totals of 6 inches or more where storms repeatedly train over the same neighborhoods.
- Mayor Zohran Mamdani activated the city's Flash Flood Emergency Plan, ordered catch‑basin clearings, staged tow and downed‑tree teams, and opened more than 50 school sites as emergency shelters.
- Officials urged New Yorkers to limit travel, never drive or walk through floodwater, make evacuation plans for basement and ground‑floor units, and sign up for 311 and NOTIFYNYC alerts as more heavy bands are expected into Monday night before conditions ease midweek.
