Henri is moving across New England and will be in the region into Monday.

The storm is bringing high winds, rain, and surges along the coast. Flooding and power outages are possible.

The National Weather Service said on Sunday night that the remnants of Henri will move back across Southern New England on Monday, and it could bring flooding, scattered showers, and storms accompanied by torrential downpours.

“Also, an isolated brief tornado can’t be ruled out Monday,” the weather service said in a tweet.

At 5 p.m. on Sunday, a map posted by the weather service showed Henri near Central Connecticut, with a potential path to western Massachusetts on Monday afternoon.

“[T]here is a danger of life-threatening inundation, from rising water moving inland from the coastline,” when storm surge warnings are issued, the center said. “This is a life-threatening situation.”

Dangerous winds may gust to 60 to 70 miles per hour in southern Rhode Island as Henri makes landfall, according to the weather service. The winds are expected to weaken as the storm heads northwest.

“Extremely strong winds will cause hazardous seas which will likely capsize or damage vessels and severely reduce visibility,” according to the weather service.

Elsewhere, winds may gust to 30 to 50 miles per hour in areas including northeast Connecticut, central and eastern Massachusetts, and northern Rhode Island during the late morning and afternoon, according to the weather service. The winds are expected to “rapidly diminish” after about 9 p.m. Sunday.

Forecasters said early Sunday morning that the latest estimate suggests it is likely that Henri will diminish to a tropical storm “rather quickly once it is over land.”

The National Hurricane Center posted the following key messages about Hurricane Henri:

  1. Dangerous storm surge inundation is expected to begin this morning in portions of Long Island, Connecticut, Rhode Island, and southeastern Massachusetts, where a Storm Surge Warning has been issued. Residents in these areas should follow any advice given by local officials.
  2. Hurricane conditions are expected to begin this morning in portions of Long Island, Connecticut, and Rhode Island, where a Hurricane Warning is in effect. Tropical storm conditions will begin in these areas within the next couple of hours.
  3. Heavy rainfall may lead to considerable flash, urban, and small stream flooding, along with the potential for widespread minor to isolated moderate river flooding over portions of Long Island, New England, eastern New York, and New Jersey.
  4. Swells from Henri will continue to affect much of the East Coast during the next day or so. These swells could cause life-threatening surf and rip currents.
