The NHC forecast track has Arthur passing about 60 miles to the east of Melbourne tonight while on a northerly heading with sustained winds of 50 knots near the center. The radius of tropical storm force winds has been expanded to 50 miles in the southwest and northwest quadrants. With a circular center that is 20 miles in diameter, tropical storm force winds should be right on the coast or just offshore from it in east central Florida later tonight and Wednesday morning.
