So, the NHC has moved the track center back east about 60 miles, so instead of landfall in far NE coastal Maine near Machias, the predicted landfall splits the uprights between the Maine/Canada border and the western tip of Nova Scotia, with the storm making landfall in Saint John in New Brunswick Canada (after brushing that tip of Nova Scotia); the track takes the storm about 25 miles SE of the Maine/Canada border, so Downeast Maine is still in the crosshairs here (and landfall could wobble back to being in Maine).
Lee will still be a Cat 1 hurricane around 2 pm Saturday when it's about 100 miles SSW of the mouth of the Bay of Fundy, between Eastport Maine and the western tip of Nova Scotia and the storm will be starting the transition to an extratropical storm, which is somewhat semantics at this point, as the storm will still be packing 70-75 mph winds when it makes landfall. Hurricane watches are up from Stonington, Maine to the Maine/Canadiand border and presumably for NB/NS Canada and Tropical Storm Watches are up from Watch Hill, RI to Stonington, ME. These will likely become warnings by tomorrow night.
This is not going to be a generally catastrophic storm, but 70-75 mph winds can do some damage (as can even 50-60 mph winds where the TS watches are up and inland in Maine/Canada) and with the large size of the storm bringing a long fetch of winds, storm surges along the entire New England Coast down to LI will be 1-3 feet with 2-4 feet along Cape Cod and Cape Cod Bay, where there is a storm surge watch up. Coastal flooding will likely be minor to moderate. And 1-2" of rain in RI/SE MA, SE NH and SW ME could lead to some flooding while flooding risks are more significant for the rest of Maine, including inland where 2-4" of rain is expected (same for most of New Brunswick/Nova Scotia).
For NJ/NYC, coastal flooding is not expected, but heavy surf, beach erosion and riptides will continue from now through Saturday. Saturday will be a beautiful day with highs in the mid-70s, partly cloudy skies and comfortable humidity; however it will be breezy with 10-20 mph winds.
