  • Tropical Storm Warning from New York City to Martha’s Vineyard (the Hurricane Warnings have been discontinued as of 8 a.m. Sunday)
  • Storm Surge Warning for Long Island Sound, South Shore western Long Island, Narragansett Bay RI, Nantucket Sound

As of Sunday morning, Tropical Storm Henri is located about 40 miles south of Montauk Point NY, moving to the north-northwest at 16 mph. Maximum sustained winds are 70 mph.

Henri will make landfall on western Long Island in a few hours. This track is most hazardous for western Long Island, the CT and RI Coasts and the southeastern MA coast, as it will bring significant storm surge to these areas along with strong tropical storm force winds.

Tropical Storm force winds are likely on Long Island and the southern New England Coastline starting this morning. Destructive winds (greater than 60 mph sustained) are likely over much of western Long Island and along the western CT and RI coasts. There will likely be a 3-5 foot storm surge in Long Island Sound, the south shore of western Long Island, Narragansett Bay, Buzzards Bay and Nantucket Sound. Expect a 2-4 foot storm surge in Cape Cod Bay and the south shore of eastern Long Island.

In addition to the winds and storm surge, Henri will bring up to 4-6 inches of rain to the NY Lower Hudson River Valley, western CT and western MA. RV’ers in these regions should be on the alert for flash flooding and be very careful camping near streams or small rivers that could rise rapidly Sunday night and Monday.

Please follow the directions and guidance of your local emergency management officials. In addition to the obvious hazards today over Long Island and the southern New England Coast, be prepared for potential flash flooding from heavy rains in the lower Hudson River Valley, western CT and western MA.

Please monitor the National Hurricane Center forecasts, either directly from their website, through local TV stations, or reputable, established weather websites.
