Multiply knots by 1.15 to get the mph and then multiply by 0.9 to get the surface winds in mph. Basically the flight level winds in knots roughly correspond to the surface winds in mph. So 67 knots at flight level would be 77 mph. Since typically surface winds are 90% of the flight level winds, you get 69 mph at the surface. Someone correct me if I am wrong here....
