At least one fatality has been attributed to Lee.

A 51-year-old man died Saturday after a tree limb fell on his vehicle in Searsport, Maine, during high winds caused by Lee, The Associated Press reported.

Lee made landfall in far western Nova Scotia around 4 p.m. as a post-tropical cyclone, according to the National Hurricane Center.

Lee continues to weaken Saturday afternoon and remains a post-tropical cyclone with maximum sustained winds of 70 mph, which is now tropical storm strength.

The center of Lee is near western Nova Scotia and will likely come ashore in Atlantic Canada in the next couple hours, akin to a routine nor'easter.

Weather conditions are improving across much of New England. Notable impacts moving forward are now focused over eastern Maine, where strong wind gusts and areas of rain will linger through this evening before it all wraps up by midnight.

A tropical storm warning remains in effect for portions of Maine, as well as across Nova Scotia and portions of New Brunswick, Canada.

Eastern Maine and western Nova Scotia are getting hit with the brunt of the rain and wind impacts from Lee. A wind gust of 52 mph was recently reported in Bangor, Maine.

Breezy conditions will persist along the New England coast this evening and tonight. Notable impacts should be done by midnight as what's left of Lee races north.

Ocean impacts will be slower to improve this weekend. Rough surf and dangerous rip currents will impact a large swath of the East Coast through this evening, then begin to diminish on Sunday.

More than 102,000 customers are without power in New England, including more than 93,000 in Maine, amid weather impacts from Lee, according to PowerOutage.us.

Hurricane Lee, now a Category 1 storm, is gradually weakening as it churns north through the Atlantic Ocean.

Lee is now about 710 miles south of Nantucket, Massachusetts, and is bringing rain and gusty winds to Bermuda.

Over the next two days, Lee will continue to weaken, but will pick up speed as it moves north, parallel to the East Coast.

The rough surf, big waves and dangerous rip currents will persist across a large swath of East Coast beaches through Saturday.

The latest forecast shows Lee's strongest winds staying offshore, so any notable wind impacts will be confined to areas right along the coast.

Rain could start along the New England coast Friday night into Saturday morning. Major flooding is not expected.

The majority of any rain or wind impacts for southeastern New England will be Saturday morning through early Saturday afternoon.

By Saturday evening, rain and winds will be slamming Maine. But most, if not all, impacts from Lee will be over in Maine by mid-morning on Sunday.

A hurricane watch is in effect for portions of the coast of Maine and into Nova Scotia, however, this could be canceled given the diminishing likelihood of any hurricane-force winds on land.
