triangle Extratropical cyclone, remnant low, tropical disturbance, or monsoon depression

During 25 March, the Fiji Meteorological Service reported that a tropical depression, had developed within an otherwise inactive monsoon trough, about 200 km (125 mi) to the west of the Fijian dependency of Rotuma.[3][4] During the next day the system initially moved north-westwards, before it turned and moved south-westwards as it organised and developed further.[3]

[5] During that day the depression moved towards the northwest, before it turned and started to move towards the southwest during 26 March as it gradually developed further. During 27 March, both TCWC Nadi and the Joint Typhoon Warning Center reported that the depression had developed into a tropical cyclone with Nadi naming it as Prema.[6]

Preparations and impact

[edit]

Severe Tropical Cyclone Prema was the first named tropical cyclone to affect Vanuatu after six systems had affected the archipelago during the previous season. Prema affected the island nation between 29 –30 March, where it caused extensive damage parts of Shefa Province, including on Epi, Efate and the Shepherd Islands.

Due to the impact of this system, the name Prema was subsequently retired, by the World Meteorological Organization's RA V Tropical Cyclone Committee.[7]
