MF suggests that Moderate Tropical Storm Gerimena rapidly degenerated tropical disturbance before slowly re-intensifying; however, the JTWC suggests it gradually intensified. Before turning west, the JTWC upgraded the system into a tropical storm midday on February 14. According to the JTWC, Gerimena reached a secondary peak with winds of 50 mph (80 km/h) before weakening a little. Meanwhile, MFR upgraded the system back to moderate tropical storm status. Slowly intensifying, Gerimena turned south. Although the JTWC suggest that Gerimena briefly weakened on January 18 while turning east, data from MFR shows that Gerimena did not weaken until 1800 UTC February 19. On January 20, however, both agencies agree that Gerimena started to re-intensify. The next day, the JTWC reported that the storm intensified into a hurricane even though MFR suggests that the system was just a disturbance by that time. Not long after becoming a hurricane, the JTWC remarked that Cyclone Gerimena had attained peak intensity.
696:(SSHWS). During the early morning hours of January 29, Ditra intensified into a severe tropical storm as the storm briefly turned west-southwest. Shortly thereafter, the JTWC announced that Ditra had attained its peak intensity of 80 mph (130 km/h). While the JTWC suggests that the storm gradually weakened during this time, MFR suggests that Ditra continued to intensify; they estimated that Ditra peaked in intensity on 0600 UTC January 30. Around this time, Ditra made its closet approach to Reunion, passing about 150 mi (240 km) south-southeast of the island. After maintaining this intensity for several hours, Ditra rapidly weakened as it accelerated to the southeast. It steadily weakened and late on January 31, the JTWC reportedly downgraded the system into a depression. Both agencies stopped monitoring Tropical Depression Ditra the following day. On January 29, Dirta passed just east of 529:. After crossing the 80°E boundary that at that time separated the two basins the following day, MFR classified the system as a tropical depression. Early on December 4, the agency upgraded the system into a moderate tropical storm. Moving steadily southwest, it gradually intensified, only to turn west on December 5. That day, MFR reported that Moderate Tropical Storm Bobalahy had attained peak intensity of 45 mph (70 km/h). Around that time, the JTWC estimated that Bobalahy attained peak intensity of 65 mph (105 km/h). After maintaining peak intensity for a day or so, Bobalahy resumed a southwesterly path far from land while slowly weakening. On December 6, MFR downgraded the system into a tropical depression; the JTWC followed suit the next day. Now moving south-southwest, the JTWC stopped issuing advisories on the system as it had become 615:-force winds; however, Celestina began to weakened thereafter. Moving south, Celestina was situated roughly 350 mi (565 km) east of Madagascar. Furthermore, on January 15, Celestina briefly re-intensified while undergoing a counterclockwise loop. By January 18, Celestina resumed a weakening trend; by that night, MFR downgraded the system into a tropical depression as it was now moving south-southwest. The storm was re-upgraded into a moderate tropical storm three days later, on January 21. However, this trend was short lived and that evening, the JTWC stopped monitoring the system. MFR followed suit at 0600 UTC on January 23. During its lifetime, Severe Tropical Storm Celestina brought rains to Reunion, peaking at 600 mm (25 in) in Trois-Bassins. 42: 929:
reported that the system regained moderate tropical storm intensity at 1800 UTC that day. Early on February 13, the JTWC upgraded Feliska into a tropical storm as it turned north. While slowing gaining strength, Feliska turned east. By 0000 UTC February 16, MFR declared that Feliska attained peak intensity. Moreover, the JTWC suggested that Feliska had peaked in intensity, with winds of 60 mph (95 km/h). Thereafter, Feliska turned south and start a slow weakening trend. On February 17, Feliska briefly weakened into a tropical depression. That night Feliska was re-upgraded into a moderate tropical storm as it made
244:. The first storm formed in mid-November, though it was not officially named. A few days later, the first official storm of the year (Anety) formed. In December, one storm formed. During January 1985, two tropical cyclones formed towards the end of the month. Three more systems developed in a short period of time in early to mid-February. After nearly two more months of inactivity, an unusually powerful late season storm developed (Helisaonina) in mid-April, which was the strongest storm of the year. While a number of storms during the season reached 959: 1012:. That evening, the JTWC announced that it had developed winds equivalent to Category 2 intensity. Two days after becoming a severe tropical storm, on April 13, the JTWC upgraded Helisaonina to the equivalent to a Category 3 hurricane. While undergoing a counterclockwise loop, the JTWC reported that Cyclone Helisaonina had peaked in intensity with 120 mph (195 km/h) winds. At that time, 000 UTC April 14, MFR estimated it attained peak wind speed, with winds of 90 mph (145 km/h). 558: 799: 880: 725: 477: 640: 391: 967: 313: 566: 807: 485: 888: 733: 399: 648: 321: 1016:

After re-curving just east of Madagascar, Helisaonina dissipated according to the JTWC on April 18. While the storm was looping close to Rodrigues, it produced wind gusts of 117 km/h (73 mph).
276:(JTWC), which is a joint United States Navy – United States Air Force task force that issues tropical cyclone warnings for the region, also tracked a long-lived tropical storm in November in addition to the 8 storms MFR named, which is comparable to the average of nine named storms per year. Following the season, the boundary for the 1015:
After attaining peak intensity, the storm weakened rapidly as it began to move west-northwest. Later that morning, MFR downgraded the system into a severe tropical storm. By April 15, MFR downgraded the system into a tropical depression. That very day, the JTWC reported that winds of Helisaonina had

On February 11, MFR reported that a moderate tropical storm formed over 700 mi (1,125 km) east of Reunion. The storm erratically drifted south for the two days when the JTWC declared the system a tropical depression. Subsequently, the system turned north-northwest and slowed. Data from the

Well away from land, the JTWC reported that a tropical disturbance developed on January 1. Initially, the storm remained weak, but later on January 11, the JTWC noted that the system had intensified into a tropical storm. Continuing to intensify, the storm moved towards the southwest. On January 12,

Shortly thereafter, data from the JTWC suggests that Gerimena weakened as it turned southeast. Then, it turned east-southeast. On February 24, Gerimena briefly level off in intensity while turning back to south. Furthermore, the JTWC stopped keeping an eye on Gerimena at 0000 UTC on February 26 as
