Cyclone Hollanda
Cyclone Hollanda was the worst tropical cyclone in Mauritius in 19 years. It formed on February 6, 1994, in the central Indian Ocean in the southern hemisphere. The cyclone moved southwestward for much of its duration, striking Mauritius on February 10 at peak intensity with winds of 155 km/h (100 mph). It later passed just southeast of Réunion before turning to the south and weakening. The cyclone became extratropical on February 14 in the southern Indian Ocean.
On Mauritius, Hollanda destroyed or severely damaged 450 houses, which left at least 1,500 people homeless. High winds left half of the island without power, and also caused severe crop damage; nearly half of the island's sugar crop was destroyed, which necessitated for the government to assist in replanting efforts. Hollanda killed 2 people and caused $135 million in damage on Mauritius. About a week after the cyclone struck, Cyclone Ivy also affected the area, although to a lesser degree. The highest rainfall from the cyclone fell on Réunion, with recorded at Grand Coude.
==Meteorological history==
Based on analysis from Météo-France (MFR), a disturbance in the Indian Ocean intertropical convergence zone became evident south of the Chagos Archipelago on February 6, after Cyclone Geralda struck Madagascar and moved away from the region.〔 The Joint Typhoon Warning Center (JTWC) assessed it as developing a day prior in the same general area.〔(【引用サイトリンク】accessdate=2011-10-02 )〕 Later on February 6, a circulation developed concurrently with an area of organized convection. On February 8, the system intensified into Tropical Storm Hollanda as it moved southwestward, its motion influenced by a ridge to its south. A trough turned the storm to the south-southwest, and Hollanda intensified into a tropical cyclone – the equivalence of a hurricane – on February 9.〔
After becoming a tropical cyclone, Hollanda developed a small eye as it tracked toward the island of Mauritius, located east of Madagascar. Continuing to intensify, the cyclone struck the northern coast of the island at 1800 UTC on February 10 at peak intensity,〔 with winds of 155 km/h (100 mph) (10 minute sustained winds) as assessed by MFR. In addition, the cyclone produced gusts to .〔 At the same time, the JTWC estimated peak winds of 195 km/h (120 mph) (1 minute sustained winds).〔 While moving over Mauritius, the eye became disrupted, although Hollanda maintained much of its intensity as it passed just southeast of Réunion early on February 11. The cyclone remained well-defined as it moved more poleward, and an irregular eye remained visible on satellite imagery. On February 13, Hollanda turned eastward due to a trough, and the next day it became extratropical over the southern Indian Ocean. Its remnants persisted at least two more days.
