The system kept that peak for only 12 hours before deteriorating to a tropical cyclone as it turned southwest.[1] Bellamine unexpectedly re-intensified back to it's peak intensity on November 7.[1] This time, the storm kept this strength for 18 hours before weakening back to tropical cyclone strength for the last time on the 8th.[1] The system quickly weakened becoming a severe tropical storm on the 9th and a moderate tropical storm later that same day.

Storm Names[edit]
A tropical disturbance is named when it reaches moderate tropical storm strength. If a tropical disturbance reaches moderate tropical storm status west of 55°E, then the Sub-regional Tropical Cyclone Advisory Centre in Madagascar assigns the appropriate name to the storm. If a tropical disturbance reaches moderate tropical storm status between 55°E and 90°E, then the Sub-regional Tropical Cyclone Advisory Centre in Mauritius assigns the appropriate name to the storm. A new annual list is used every year so no names are retired.[3]
