4 – 8 January 2020

Preliminary Summary

Best Track of Tropical Cyclone Blake
All times shows are in Australian Western Standard Time (AWST), that is UTC + 8 hours.

On 4 January 2020, a tropical low formed off the northwest Kimberley coast, about 300 kilometres north of Cape Leveque. The low was initially very slow moving, travelling towards the southwest and then stalling before moving east and developing into a tropical cyclone at 8am AWST 6 January, 120 kilometres northwest of Cape Leveque. Tropical Cyclone Blake moved southwards at a speed of 15 to 20 kilometres per hour and briefly moved over land over the Dampier Peninsula for approximately six hours on the evening of 6 January. Broome Port recorded a wind gust of 102 kilometres per hour at 4:53pm AWST 6 January. This brief period over land weakened Blake slightly, but it remained a category 1 tropical cyclone and developed again after moving offshore. In the 24 hours to 9am on 7 January, Derby recorded 152.8mm of rain, Broome recorded 148mm and roads were cut off by flood waters. Early on 7 January, Tropical Cyclone Blake moved back over water, around 30 kilometres north of Broome and then travelled parallel to the west Kimberley coast, crossing the Eighty Mile Beach 17 kilometres east of Wallal Downs at 11pm AWST 7 January

The remnant tropical low tracked west and then south through the eastern Pilbara, resulting in heavy rainfall and flooding. Moderate to major flooding was recorded over numerous tributaries of the De Grey river catchment and there were widespread road closures. The Coongan River peaked at its highest level in over 30 years of records.

Tropical Cyclone Blake was the first tropical cyclone in the Australian region for the 2019/20 season.
