Category 5 (≥157 mph, ≥252 km/h)
Unknown
Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionAn area of convection persisted on January 16 to the west of Diego Garcia,[1] and that day Météo-France (MF) classified the system as Tropical Disturbance 08.[2][1] The system maintained thunderstorms over a developing circulation, located in an area of weak to moderate wind shear. It developed outflow and gradually organized, prompting the Joint Typhoon Warning Center (JTWC) to issue a tropical cyclone formation alert on January 17. That day, the MF discontinued advisories after the system briefly halted its development trend. The disturbance continued its movement to the west-southwest. On January 19 it began intensifying.[1] That day, the JTWC classified it as Tropical Cyclone 12S to the north of the northern coast of Madagascar.[3] After continued development, MF upgraded the system to Tropical Storm Ernest on January 20.[1]
After attaining tropical storm status, Ernest entered the Mozambique Channel and turned to the southwest.[4] It developed outflow on opposite sides of the storm, and an eye gradually became evident.[1] While strengthening, Ernest moved over Mayotte and passed southeast of Comoros.[4] By late on January 20, the storm rapidly intensified over warm waters into a tropical cyclone – the equivalent of a 120 km/h (75 mph) hurricane. Around that time, Ernest had turned to the south, along the western periphery of a ridge.[1] On January 22, MF upgraded the storm into an intense tropical cyclone with peak winds of 165 km/h (105 mph 10 minute winds) when it was located off the west coast of Madagascar.[2] At around the same time, the JTWC estimated Ernest attained peak winds of 185 km/h (115 mph 1 minute sustained).[3]
While at peak intensity, Ernest was a small cyclone with gales extending 130 km (80 mi) outward from the well-defined eye.[1] After maintaining peak winds for about 12 hours, the cyclone began weakening while turning to the southeast.[2] On January 23, Ernest made landfall on the southwest coast of Madagascar at Itampolo,[4] with winds estimated at 130 km/h (80 mph). The cyclone accelerated to the southeast across the island and quickly weakened into a tropical storm. Late on January 23, the JTWC issued its last advisory after Ernest began transitioning into an extratropical cyclone.[1] Early the next day, MF declared Ernest extratropical, and continued tracking it until the storm dissipated on January&nbs;25 in the southern Indian Ocean.[2][4]
Impact and aftermath
The storm first struck Mayotte, affecting the island with gale-force gusts for about six hours. Sustained winds reached 78 km/h (48 mph), and wind gusts peaked at 98 km/h (61 mph).[1] Effects on the island were minimal. Cyclone Ernest indirectly affected Malawi, located inland in southeast Africa. The storm's circulation removed moisture from the country and prevented any rainfall from occurring in the southern part of the country during a nine day period.[4]
In southern Madagascar, the cyclone produced high winds and heavy rainfall. The highest rainfall was a 24 hour total of 237.2 mm (9.34 in), and the highest wind gust was 180 km/h (110 mph), both of which observed in Toliara. Many fishermen in the area were not aware of the storm's approach, and several of them died as a result. About five days after Cyclone Ernest struck Madagascar, Tropical Storm Felapi struck the same general area, causing additional flooding. The combined effects of Ernest and Felapi killed 39 people, injured 104, and left 214 people missing as of February 25, 2005. The storms damaged 5,792 buildings, and there were 32,191 people left homeless. The floods damaged about 4,483 hectares (11,078 acres) of crop fields in southern Madagascar.[4] Portions of the country faced shortages of rice due to crop damage from Ernest, as well as from Cyclone Gafilo in the previous year. This caused prices to increase, resulting in street protests.[5] As a result, the World Food Programme provided 45 tons of rice to affected residents, although persistent flooding disrupted relief work. In general, damage from Ernest and Felapi were less than that from Gafilo in the previous year.[6]
