Heavy Rain Will Threaten Parts of State Through Wednesday

October 25, 2021


Two Rounds of Heavy Rain Forecast for Parts of New York City, Long Island and Mid-Hudson Beginning Monday Night and Continuing Through Wednesday Morning

Some Areas Could Receive Four or More Inches of Rain Over the Multi-Day Rain Event

High Winds Could Cause Downed Trees and Power Lines, and Combination of Heavy Rain, Saturated Soil and Wind Could Uproot Some Trees


Governor Kathy Hochul today directed state agencies to prepare emergency response assets as a rapidly developing low-pressure system is expected to produce heavy rainfall across most of Long Island, New York City, and the Mid-Hudson Region. Two rounds of heavy rain are expected with the first round beginning Monday night and the second round on Tuesday evening.


Rainfall totals of 2-4 inches with locally higher amounts are possible, and rainfall rates may exceed one inch per hour at times. Heavy rainfall combined with already saturated soils will likely cause flooding in various locations, and high winds may cause downed tree limbs and power lines. Heavy rain, wind, and saturated soil could result in some uprooted trees. Governor Hochul urged New Yorkers to pay attention to updated weather forecasts and follow any local emergency orders that may be issued.



"This fast-moving weather system is expected to bring a lot of rain to the downstate area through Tuesday night, and New Yorkers should keep a close eye on the forecast so they can be prepared for any inclement weather that may come their way,"

Governor Hochul said.


"I have directed State agencies to prepare emergency response assets and to be ready to deploy them in the event our local governments and communities in those regions are in need of assistance. We stand ready to help our fellow New Yorkers."

A Flash Flood Watch is in effect for Long Island, New York City, and counties within and near the lower Mid-Hudson Region through Tuesday afternoon. A Wind Advisory is also in effect for Suffolk County from Tuesday afternoon to Wednesday morning as wind gusts up to 50 mph could bring down tree limbs and power lines, and saturated ground from heavy rainfall could result in some uprooted trees.
