on December 3, Bako weakened back into a severe tropical storm due to much cooler sea surface temperatures and increasing northwesterly wind shear. It weakened into a tropical depression on December 5, before transitioning into an extratropical cyclone the same day. RSMC La Reunion continued to track the remnants of Bako until December 9. Severe Tropical Storm Cyprien On December 25, a cold front dragged over the central Mozambique Channel. A weak circulation formed in the Channel and moderate convection appeared on December 27. Then on December 30, RSMC La Reunion designated this low pressure as a zone of disturbed weather and was classified as a tropical depression on January 1, 2002. The JTWC also issued a Tropical Cyclone Formation Alert (TCFA) early on December 31 and designated it as Tropical Cyclone 08S the next day. As it moved further eastwards it strengthened quickly from a tropical depression into a severe tropical storm, with the Meteorological Services of Madagascar giving it the name Cyprien on January 1. Cyprien soon became a serious threat to western Madagascar. Convection began to dissipate as wind shear increased and that resulted in quick weakening to a tropical depression. As it made landfall on western Madagascar, it dropped heavy rainfall. In all, Cyprien destroyed 841 homes in the towns of Morombe and Morondava. Damage in the towns was estimated at $180,000, but there were no deaths. Intense Tropical Cyclone Dina Cyclone Dina originated in a tropical disturbance first noted on January 15 near the Chagos Archipelago. By January 17, the system had developed enough organized convection as it moved southwestward to be declared a tropical depression. Rapid intensification occurred shortly thereafter, with the system attaining winds in excess of 120 km/h (75 mph) on January 18. Dina peaked in intensity on January 20 as an intense tropical cyclone with winds of 210 km/h (130 mph). Hours later, the storm bypassed Rodrigues Island about to its north. On January 21, the storm brushed Mauritius and Réunion as an intense tropical cyclone before turning southward. Once on a southward course, steady weakening ensued and the system eventually transitioned into an extratropical cyclone on January 25. The remnants of the storm accelerated southeastward and were absorbed into a polar trough on January 28. Across Mauritius and Réunion, torrential rains and destructive winds from the cyclone resulted in extensive to "catastrophic" damage. The entire island of Mauritius lost power
