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 southeast Connecticut. 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.
