[1] The wind gust was evaluated by the WMO Evaluation Panel who found that the anemometer was mechanically sound and the gust was within statistical probability and ratified the measurement in 2010, however, the wind speed was measured inside of the cyclone and not at ground level.
[2] During the cyclone several extreme gusts of greater than 300 km/h (160 kt) were recorded, with a maximum 5 minute mean speed of 176 km/h (95 kt), the extreme gust factor was in the order of 2.27-2.75 times the mean wind speed. The pattern and scales of the gusts suggests that a
mesovortex was embedded in the already strong
eyewall of the
cyclone.
