An observation from Great Gull island, located about 6 miles northeast of the north fork of Long Island, measured a sustained wind of 60 mph at 1101 AM EST, and gust to 69 mph at the same time. Winds across this area were generally sustained at 30 to 40 mph with gusts 40 to 50 mph.

Wider weather episode

Tropical storm Henri with maximum sustained winds of 60 mph made landfall on the Rhode Island coast, near Westerly, at 12:30pm EDT Sunday, August 22. Henri then continued turning to the west as the storm weakened over Connecticut becoming a depression by evening. Henri meandered towards the Lower Hudson Valley of New York as the storm continued to interact with an upper level trough, before being swept eastward off the New England coast late in the day on Monday August 23, 2021.

Tropical storm force winds were limited mainly to the twin forks of eastern Long Island. This resulted in a few reports of tree limbs being downed and power outages.

The greatest impact from Henri was flooding due to heavy rainfall in and around the New York City metro, both from a predecessor rainfall event during the evening hours of Saturday, August 21, and then with the circulation of Henri throughout much of the day on Sunday, August 22.
