Hence conventional Dvorak is no longer applicable to the intensity nor standard objective TC aids. Gabrielle passed within 30km of Norfolk Island which reported a minimum pressure of 958.1hPa at 11UTC Saturday. Fortunately Norfolk Is evaded the highest winds, the airport recording only near-gales and maximum wind gust 102 km/h (55 knots) at 0336UTC on Saturday. The current wind intensity (55kn) and wind structure are based primarily on model guidance which is quite consistent and agrees with recent ASCAT-B at 1030UTC having partial coverage of western sectors. The synoptic environment is unfavourable to sustain a true tropical cyclone as strong wind shear persists and the system is now over SSTs below 25C, and moving into even cooler SST. Gradual weakening is forecast although baroclinic processes provided by the upper trough to the west is sustaining the system. Observed winds at Norfolk Island have eased as the system moves away, mirroring model guidance trends of rapid weakening in the western quadrants overnight. Gales are no longer expected to affect the island. Gabrielle will remain a robust circulation into Monday and Tuesday as it moves closer to New Zealand.
