We're a few miles south-west of Exeter and I can remember hearing the wind hitting the house during Monday night/Tuesday morning so 10 knots seems like a surprisingly low forecast. Looking at FR24 the ground speed on approach was varying fairly rapidly between 111 and 133 knots, so I'm guessing they were dealing with some reasonable gusts. Data also shows a VS of -1,024 FPM over the threshold, but the aircraft was apparently still airborne as it reached the intersection with the old RWY13/31.
