Tropical Cyclone George crossed the Pilbara coast east of Port Hedland in the late evening of Thursday 8th March 2007. The peak gust speeds in Greater Port Hedland standardised at 10 m height in Terrain Category 2, were previously estimated at up to 200 kph (~55 m/s). The damage appeared to have been caused by winds within the quadrant South-East through to South-West. Wind speeds in the region affected by the first 120 km of the cycloneâ€™s track after landfall were estimated from damage to simple structures and to vegetation. All of the estimated wind speeds were less than the design wind speeds presented in AS1170.2-2002 with the relevant FD and FC factors. This event has shown no cause to modify the modification factors FD and FC. The cyclone crossed very close to the northern extremity of wind region D, with estimated wind speeds at landfall close to the design wind velocities for that region. Had the crossing been in region C, the design wind speeds would have underestimated the winds caused by the event. Consideration should be given to moving the boundary of region D further northward.
