Tropical Cyclone Caleb

Western Australian Regional Office

Track of Tropical Cyclone Caleb

Caleb was first identified as a tropical low in a monsoon trough during 22 March, approximately 240 kilometres north of the Cocos (Keeling) Islands. The low moved in a southeasterly direction, and gales developed to the north of the system later on 22 March. During 23 March gales extended around the remainder of the system and Tropical Cyclone Caleb was named at 2pm AWST on 23 March, when it was about 400km east of the Cocos (Keeling) Islands.

Caleb developed slowly during the next 48 hours as it drifted in a general southerly direction, away from Cocos (Keeling) and Christmas Islands. Once Caleb moved south of 15S, it tracked in a westerly direction, and by early on 27 March had weakened below tropical cyclone intensity due to a combination of dry air and cooler sea surface temperatures.

Cocos (Keeling) Islands experienced a period of heavy rainfall and gusty winds during 21 and 22 March due to the effects of the monsoon flow that lead to the formation of Caleb. The system itself did not cause any wind or rainfall impacts on the Islands or mainland Western Australia, due to it remaining over open water.

Tropical Cyclone Caleb was the fourth tropical cyclone in the Australian region for the 2016/17 season.
