MIAMI, Florida, August 20, 2021 (ENS) – Hurricane Hunter Aircraft from NOAA and the U.S. Air Force Reserve flying into the midst of what is now Tropical Storm Henri off the coast of North Carolina report maximum sustained winds near 70 mph (110 km/h) with higher gusts.
When the storm makes landfall somewhere on Long Island or in southern New England later this weekend, it’s expected to be a hurricane, packing winds stronger than 74 mph.
Strengthening is forecast during the next day or so, and Henri is expected to become a hurricane tonight or Saturday and be at or near hurricane strength when it touches land on Sunday.
Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center of the storm.
Henri may produce rainfall amounts of three to six inches over Long Island and New England Sunday into Monday, with isolated maximum totals near 10 inches, says the National Weather Service, NWS.
Heavy rainfall from Henri could result in considerable flash, urban, and small stream flooding, along with the potential for widespread minor and isolated moderate river flooding, the NWS predicts.

A Storm Surge Watch is in effect for Flushing, New York to west of Greenwich, Connecticut, Chatham to Sagamore Beach, Massachusetts, and Cape Cod Bay.
The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances, the National Weater Service explains.
Swells that could cause life-threatening surf and rip current conditions are expected to increase across much of the east coast of the U.S. and Atlantic Canada tonight and into the weekend.
