Cyclone Craig (2003)
Encyclopedia
Cyclone Craig was a moderate tropical cyclone
Tropical cyclone
A tropical cyclone is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rain. Tropical cyclones strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor...

 late on 11 March.

Once over open waters, the storm system continued to accelerate as it turned southeastward and eventually east-southeastward. Due to relentless wind shear, the storm had difficulty in regaining organization and the circulation structure had become asymmetric. As Craig approached the eastern Gulf of Carpentaria, the apparent center visible on radar continued tracking southeastwards. However, the low-level center slowed and remained stationary for around 12 hours. On 12 March at 0600 UTC, the cyclone made its final landfall, south of Kowanyama. On moving ashore, the storm quickly weakened and slowed. Shortly thereafter, wind shear caused it to dissipate that night.

Preparations and impact

 evacuated some residents to shelters. In and around Darwin, certain schools were closed temporarily as a precaution. However, the city and surrounding regions were spared severe conditions.

Damage from the storm was generally insignificant due to the sparse population in the areas affected, and no casualties were reported. At Ramingining, 164 mm (6.5 in) of rain fell in just 24 hours. Storm surge ran 2 to 2.5 m (6.6 to 8.2 ft) on Goulburn Island and the Cobourg Peninsula
