C-band radar from Saddle Mountain, 10km NNW of Cairns, for the period 6.12am (20.12UTC) to 10.22am (00.22UTC). Places marked on the diplay are BAB=Babinda, IFL=Innisfail (with a small red circle), TUL=Tully, ATH=Atherton, HER=Herberton and RHOE=Ravenshoe. Note that although torrential rain was occurring south of the eye towards Tully, it was screened from the radar by the Bellenden Ker Range and Mt Bartle Frere to the NW of Innisfail.

  • 6.12EST (20.12UTC) in the first frame, the western wall of the eye, which is some 35km in diameter, arrives at the coasline east of Innisfail
  • 6.41 (20.41): the western wall is already starting to break down in the South Johnstone area. The South Johnstone Experimental Station AWS measured a maximum gust of 182km/h at 6.33am, and its highest measured average wind speed was 89km/h over the 10 minutes to 6.50am. This dropped to a relatively breezy average of 65km/h during the next 10 minutes.
  • 7.21 (21.21): the northern eye wall begins to deform as it interacts with elevated terrain: Cooroo Peak and Mt Chalmynia 15km to the west and Mt Arthur 12km to the north of Innisfail are all between 400 and 500m asl.
  • 8.21 to 8.51 (22.21 to 22.51): The wall is now irregular but still distinct as the eye moves into rough country 800 to 1200m asl on the southern flanks of the Atherton Tableland south of Malanda. Its western movement has slowed somewhat.
  • 9.32 to 10.01 (23.32 to 00.01): The eye rapidly breaks down between Herberton and Ravenshoe. By 10.30am, the Bureau estimated TC Larry to be 55km SW of Mareeba with a central pressure of 945hPa and winds still gusting to 220km/h.
