Hurricane Lee remains a very large hurricane over the western Atlantic with max winds near 70 knots and moving north-northeast at 16 knots.
Hurricane force winds extend out 90 nm to the northeast and 70 nm to the southwest. 50 knot winds extend out 160-170 nm to the east and 110-150 nm to the west. Maximum significant wave heights are estimated near 14 meters (46 feet).
Lee is expected to make landfall in Atlantic Canada in 24 to 36 hours. After landfall, Lee is forecast to accelerate to the northeast. Wind shear and colder sea temperatures will weaken Lee which is forecast to become extratropical by landfall with max winds of 55-60 knots.
