Tropical Storm Henri made landfall in Rhode Island on Sunday afternoon. The storm’s winds will weaken as Henri pushes inland over the next couple of days, but the threat for flash flooding remains a concern. The storm could have some minimal effects in Atlantic Canada early this week. More on Henri’s impacts, below.

HENRI MADE LANDFALL IN RHODE ISLAND ON SUNDAY

Henri officially made landfall at 12:15 p.m. EDT in Westerly, Rhode Island, with maximum sustained winds of 95 km/h. A wind gust of 113 km/h was reported near the mouth of Narragansett Bay in Rhode Island as the core of the storm passed overhead.

The storm’s winds began to recede as it moved inland, and Henri weakened to a tropical depression on Sunday evening with maximum sustained winds of 55 km/h.

Forecasters with the U.S. National Hurricane Center (NHC) expect the system to weaken to weaken further on Monday, eventually degenerating into a post-tropical low-pressure system by Tuesday.

The system and its remnants will meander in New England on Monday before accelerating east toward Atlantic Canada on Tuesday.

The surplus of tropical moisture over the northeastern U.S. could lead to additional rainfall totals of 50-100 mm for parts of New York, New Jersey, Connecticut, and Massachusetts through Tuesday.

Heavy rainfall from Henri may result in considerable flash, urban, and small stream flooding, along with the potential for widespread minor to isolated moderate river flooding.

The risk for a tornado or two continues through Sunday night across parts of southern New England.

ATLANTIC CANADA IMPACTS?

The remnants of Henri will cross the southern Maritimes early in the new week, and may extend north to southern Quebec.

The system could enhance rainfall totals across parts of the Maritimes, with 20-30 mm of rain possible in portions of New Brunswick through Wednesday morning.

No significant wind is expected over Maritimes land areas at this time, according to Environment and Climate Change Canada (ECCC).
