That translates to about 95 kt at the surface. If higher up, then a case for 100 kt could be made.
Any insight as to why/how NHC expects Sally to stay offshore until 1200z?
landfall actually occurs when the "EYE" is situated half on half off.. so the red line at this point in time needs to be on land for it to have made landfall. the distance from shore to the red line is roughly 15-18 miles so you divide that by the 2 MPH speed and you get 7.5 - 9 hrs before landfall is declared ..
