HOLBROOK, NY (OnSachem.com / OnTownMedia.com) — The National Weather Service has issued a Hurricane Warning for Suffolk County and a Tropical Storm Warning for Nassau County as Henri moves north along the East Coast. The storm, currently a tropical storm, is expected to strengthen to a hurricane as it makes landfall early Sunday afternoon.
As of Friday evening according to the National Weather Service, Tropical Storm Henri is 660 miles south of New York City or about 690 miles south of Montauk Point. Henri will likely track north nearing eastern Long Island and southern New England Sunday as a Category 1 Hurricane. The updated forecast track throughout the day on Friday has continued to shift west, and now has Henri making landfall in Suffolk County instead of the eye passing east of Montauk.
The main threats from Henri are potentially life-threatening storm surge, heavy rain capable of producing flash flooding, and tropical storm or hurricane force winds across Long Island and across southern Connecticut. Tropical storm conditions are also possible as far west as New York City. In the greater Sachem area, peak winds are forecasted to be 35-45 mph with gusts to 65 mph. There is the potential for wind as strong as 74 to 110 mph. The window for Tropical Storm force winds is early Sunday morning to until early Monday morning.
A widespread rainfall of 3 to 6 inches is forecast in the path of Henri with localized higher amounts possible Sunday through Sunday night. The highest amounts are forecast to be along and west of the center of Henri. This will present a likelihood for areas of flash flooding.
Dangerous marine conditions are likely on the waters surrounding Long Island, including the Long Island Bays. Severe beach erosion is also possible. Dangerous rip currents are expected at ocean beaches.
In advance of the storm's arrival, PSEG-LI warned that some power outages could last 7 to 10 days.
