Meteorological history
Шаблон:Storm path Severe Tropical Cyclone Laurence was first identified by the Australian Bureau of Meteorology (BoM) on 8 December 2009 over the Arafura Sea.[1] As the system moved west north of the Top End on 10 December, TCWC Darwin issued a Tropical Cyclone Watch for coastal areas from Croker Island to Bathurst Island but excluding Darwin.[2] Later that day, TCWC Perth cancelled all previous warnings and issued new watches for Kalumburu, south to Wyndham and west to Mitchell Plateau.[3] The system hovered in the same general region for a day, before strengthening into a category one cyclone, and was named by the TCWC Darwin as Tropical Cyclone Laurence. During the morning of 15 December, the cyclone strengthened into a category 2 cyclone before strengthening further into a category 3 system.[4] In the early hours of 16 December Severe TC Laurence was upgraded to a strong category 4 with an eye starting to develop; later developing into a category 5 system.[5] The cyclone crossed the Kimberley coast southeast of Cockatoo Island on 16 December and Derby was in the projected path.[6]
On 17 December the cyclone weakened as it meandered over land dumping heavy rain over northern Kimberley. The cyclone's track during the day veered south-west and re-intensification was likely by 18 December as it moved over warm waters.[7] On 19 December, the storm re-intensified into a category one cyclone and began moving slowly southwest, and further intensified into a category 2 the same day.[8] On 20 December it intensified into a category 3 severe tropical cyclone, and showed signs of further intensification.[8] On 21 December, the cyclone rapidly intensified into a category 4, and then 5 by the afternoon. The cyclone made landfall on the Western Australia coast near Eighty Mile Beach as a category 5 storm with significant damage to structures reported, although no injuries have been reported. Telephone services to the affected area were disrupted.[9] Overnight, the system began moving inland and rapidly picking up speed, while gradually weakening into a category 3 tropical cyclone.[9] By early 23 December, the cyclone had weakened to Category 1 intensity, but not before inundating eastern Pilbara region with rain and flash flooding.[10] Laurence accelerated even further, and was expected to cause gale-force winds and flooding rain as far as South Australia.[8]
Preparations and impact
As a tropical low, the precursor to Laurence produced Шаблон:Convert of rain in Darwin, Northern Territory in a 24-hour span.[11] One person was seriously injured after falling off a roof in the Kimberley, Western Australia.[12]
After making its final landfall along the Pilbara coastline as a Category 5 cyclone, Laurence wrought severe damage. Numerous trees were uprooted by wind gusts reaching Шаблон:Convert and several homes sustained substantial damage. Rainfall in the region was estimated to have exceeded Шаблон:Convert. Power and phone service to most of the Pilbara was lost during the storm and several residents sought shelter in public buildings.[13] Although no people were killed by the storm, hundreds of livestock were feared to have been killed in the affected region.[14]
Heavy rain and gale-force winds associated with the cyclone forced the closure of Newcrest Mining Ltd's Telfer gold mine for a day as all non-essential workers were flown from the site.[10]
New South Wales' river systems were put on flood alert as rain fell widely. Systems affected were:
- Castlereagh River,
- Bogan River,
- Lower Namoi River, and
- Lower Macquarie Rivers, and
- the Barwon River and associated Darling River between Walgett and Bourke.[15]
Damage from the storm amounted to A$10 million (US$9 million).[16]
