September 28, 2023 — The New York City Emergency Management Department has issued a travel advisory for Friday, September 29 through Saturday morning, September 30. The National Weather Service has issued a Flood Watch for New York City beginning at 2 a.m. Friday through 6 a.m. Saturday. According to the latest National Weather Service forecast, heavy rain is expected citywide beginning as early as 2 a.m. Friday through tomorrow night. Citywide average rainfall amounts of 2 to 4 inches are forecast, with locally higher amounts in excess of 5 inches possible. Persistent heavy rainfall may result in numerous flash floods. The excessive rain runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Potential street flooding may also occur. Widespread travel impacts are possible, particularly during the morning commute tomorrow. There are no significant winds hazards or thunderstorms expected.

“New York City will be under a flood watch starting tomorrow and we urge New Yorkers to prepare for heavy rain and potential flooding throughout Friday and Saturday morning,” said NYC Emergency Management Commissioner Zach Iscol. “All New Yorkers need to exercise caution. If you must travel, consider using public transportation and allow for extra travel time, and if you must drive, do not enter flooded roadways. If you live in a basement apartment, especially in a flood prone area, be prepared to move to higher ground.”

NYC Emergency Management and its partners have activated the Flash Flood Plan and are working with the National Weather Service to monitor conditions. Crews from the Department of Environmental Protection and the Department of Transportation are inspecting and cleaning catch basins in neighborhoods and roads vulnerable to flooding.
