Henri weakens to tropical storm
Henri weakened from a hurricane to a tropical storm when it dropped from 75 mph max sustained winds to 70 mph.
However, tropical storm conditions are continuing to spread across parts of southern New England, the National Weather Service reported.
Outer bands begin to reach New England coast
Henri is currently a category 1 hurricane with 75 mph max sustained winds as outer bands start to reach the southern New England coast and Long Island.
Hurricane warnings are in effect for Long Island, Connecticut and Rhode Island, and tropical storm warnings stretch from New Jersey to Massachusetts.
Flash flood warnings have been ongoing as heavy rain has moved through, with around 4.5 inches of rain falling in Central Park — at a rate of almost 2 inches per hour -- and 6 inches falling in Brooklyn. This is just the beginning of the rain the Northeast will see as Henri moves through.
Flood watches are posted from Delaware to Vermont, and rain totals may reach or exceed 10 inches.
The path is sticking east, and it appears that the center of Henri could stay just off the eastern edge of Long Island, before making landfall early afternoon in Rhode Island at or near hurricane strength.
Once landfall occurs, rapid weakening is expected.
The storm conditions will likely cause numerous power outages, and an isolated tornado is also possible.
Flooding a major threat for Northeast
Flash flood warnings are already in effect across New York City, Staten Island and northern New Jersey due to moisture funneling into the region from an upper level system to the west of Henri.
Flooding from Henri, which continues to hold onto hurricane status with 75 mph max sustained winds, will be a widespread threat across the Northeast on Sunday.
Henri is moving north at 21 mph and is 135 miles south-southeast of Montauk Point, New York, and 175 miles south of Providence, Rhode Island. Slight strengthening is possible, and Henri is expected to be at or near hurricane strength when it reaches the coasts of southern New England and Long Island.
Over 53,000 without power in 2 states
More than 53,000 customers across two states were still without power early Monday morning as Henri slowly moved over the New England area.
As of 5 a.m. ET, there were 44,104 customers without power in Rhode Island, where Henri made landfall, while 9,737 were without power in Connecticut, according to data collected by PowerOutage.US.
