Severe Tropical Cyclone Gillian

18 – 27 March 2014

Summary

A low formed over the eastern Arafura Sea on 6 March 2014 and developed into a tropical cyclone on 8 March. Gillian moved slowly around the Gulf of Carpentaria for about a week, weakening below tropical cyclone strength on 10 March. The low briefly re-developed into a tropical cyclone on the 14 -15 November before the remaining low moved north and then west passing to the north of the Northern Territory. The low tracked westward across the Indonesian Islands from 18 – 20 March. During 20 March the low moved in a west southwest direction over open water and intensified under favourable conditions. Gillian passed very close to Christmas Island on 22 March with the island experiencing a period of near gales during the afternoon. A peak wind gust of 52 knots (kn) (96 kilometres per hour (km/h)) was recorded and 181 millimetres (mm) of rainfall was recorded in the 24 hours to 9 am Australian Western Standard Time (AWST) 22 March. There were reports of structural damage on the island with several buildings incurring roof damage, power lines downed and trees felled.

Gillian turned south and rapidly intensified. The tropical cyclone reached a peak 10-minute mean wind intensity of 120 kn (222 km/h) at 1800 Universal Time Coordinated (UTC) 23 March (AWST = UTC + 8 hours). Gillian weakened quickly from this point as the vertical wind shear increased. The tropical cyclone weakened to below cyclone strength by 1800 UTC 25 March and the remaining low tracked to the west until it dissipated on 27 March.
