2002–03 South-West Indian Ocean cyclone season

Later, Tropical Storm Fari crossed southern Madagascar with heavy rains, causing flooding and mudslides that left 3,400 people homeless.

Cyclone Japhet struck southern Mozambique and produced widespread flooding in south-eastern Africa, killing 25 people.

The disturbance was located at a low latitude near the equator, and a ridge extending from the eastern coast of Africa imparted a general west-south-west movement.

[8] Post analysis from MFR indicated that the system reached peak winds of 65 km/h (40 mph) on September 6,[9] the same day that the Joint Typhoon Warning Center (JTWC) initiated advisories on it as Tropical Cyclone 01S.

Late on November 6, JTWC estimated peak winds of 85 km/h (53 mph), around the same time that Atang began a slow motion to the southwest.

Atang passed near the north coast of Madagascar on November 10 after turning to the west, and that day the JTWC again discontinued advisories.

[15] In Tanzania, there were unofficial reports that Atang killed several fishermen and caused heavy rainfall with wind gusts to 148 km/h (92 mph).

Initially, the storm retained good outflow and convection,[12] and Boura passed just north of St. Brandon on November 19, producing 54.5 mm (2.15 in) of rainfall and wind gusts of 106 km/h (66 mph).

[12][16] While the storm turned to the west and northwest, it interacted with the ridge to the south to produce wind gusts of 118 and 111 km/h (73 and 69 mph) on Mauritius and Réunion, respectively.

[21] The storm damaged roads and bridges, which disrupted relief efforts in the aftermath,[22][23] and floods destroyed widespread areas of crops in the midst of an ongoing food shortage.

On January 10, the JTWC upgraded Ebula to the equivalent of a minimal hurricane, and estimated peak winds of 115 km/h (71 mph), just shy of tropical cyclone status.

[28] An area of convection persisted on January 20 to the east-south-east of Diego Garcia, quickly developing outflow due to minimal wind shear.

[29] Tropical Storm Fari struck Madagascar after the country had experienced weeks of heavy rainfall, causing widespread flooding.

The next day, MFR upgraded the depression to tropical storm status, and the Meteorological Services of Mauritius named the system Gerry.

[30] Around that time, Gerry began undergoing rapid deepening, becoming an intense tropical cyclone early on February 13 while developing a well-defined eye and outflow.

[30] Early in its duration, Gerry passed just west of Tromelin Island, producing tropical storm force winds and gusts to 111 km/h (69 mph).

The cyclone originally threatened to strike Mauritius directly, but due to a more east-south-easterly motion, Gerry passed more to the east.

Gerry dropped heavy rainfall, peaking at 139.2 mm (5.48 in) at Mare aux Vacoas, and it produced high waves along the northern coast.

[34] Operationally, MFR first began issuing advisories on February 9 for Tropical Disturbance 11, when the system had a small center and accompanying convection.

Outflow decreased due to interaction with Cyclone Gerry to the west,[31] and Hape weakened to tropical storm status on February 13.

[35] Cyclone Japhet developed on February 25 near the south-west coast of Madagascar, and initially moved to the north-west before turning to the southwest.

With favorable conditions for development, Japhet quickly intensified in the Mozambique Channel, reaching maximum winds of 175 km/h (109 mph), sustained over 10 minutes.

After stalling briefly, the cyclone turned to the northwest, weakening slightly before striking Mozambique just south of Vilankulo on March 2.

The rains occurred after an extended drought, although excessive precipitation caused heavy crop damage, notably around where the storm moved ashore.

[39][40] When the cyclone passed Rodrigues, it produced wind gusts estimated up to 210 km/h (130 mph), which caused an island-wide power outage.

The circulation became exposed on April 9, but when it began quickly intensifying the next day, MFR initiated advisories on Subtropical Depression Luma.

On April 11, Luma developed an eye in the center of the thunderstorms,[46] prompting MFR to upgrade the storm to peak winds of 130 km/h (81 mph).

Manou developed a well-defined eye and reached peak winds only 19 km (12 mi) from the eastern Madagascar coastline.

[4] When Manou struck Madagascar, it produced gusts as strong as 211 km/h (131 mph) and heavy rainfall reaching 227 mm (8.9 in) in a 15‑hour period, both at Vatomandry.

[51][52] The storm destroyed large areas of crops and disrupted transportation, including damaging the road between Vatomandry and Brickaville.

Four tropical storms active on February 12; from left to right are Gerry, Hape, the system that would become Isha, and Fiona in the Australian region
