Update (8 p.m.): A coastal flood warning has now been issued for our area as a nor’easter gets set to slam lower New York Sunday night into Tuesday.

A flood warning means that flooding is expected or occurring.

The storm will likely be most severe Monday afternoon and evening.

Original story: The National Weather Service has issued a Coastal Flood Watch for our area.

Residents are being told to expect high winds and heavy rainfall starting Sunday night into Monday evening.

Governor Andrew Cuomo also issued a statement today, urging New Yorkers, especially those in New York City and Long Island to prepare not only for heavy rain, but snow, sleet and freezing rain.

Widespread dune erosion and localized wash overs are possible along the Atlantic Ocean coast, according to the governor’s office.

Sea levels may be between 16 and 22 feet on the ocean and 6 to 12 feet on the sound.

“As this storm could cause power outages across downstate and flooding for communities near the coastline, I am directing all relevant state agencies to be on alert and ready to respond to whatever Mother Nature throws our way,” reads Cuomo’s statment. “We will be closely monitoring storm conditions and deploying resources and equipment as necessary. I encourage all New Yorkers in these areas to plan ahead, avoid unnecessary travel, and above all else – stay safe.”

Wind speeds of 30 to 40 mph are likely, and 60 mph gusts are possible. Such winds could lead to downed trees and power lines, so residents should be prepared for power outages.

The high winds, coupled with tidal surges, could create flood conditions in our coastal communities.
