Madagascar: 5 Tropical Cyclone Fantala, NASA

Tropical Cyclone Fantala a major tropical cycle in Southern Indian Ocean reaching category of 5 status on Saffir –Simpson Hurricane Wind scale. NASA had observed a powerful wind wrapped tightly around the eye and satellite also indicated well structured storm with wide eye on April 18 at north of Madagascar.  On April 17 at 6.am RapidScat instrument that flies aboard to measure Fantala’s surface wind space over southern Indian Ocean record 30 meters per second (67 mph/108 kph) entire center of storm.

On April 18 at 10:25 UTC (6:25 am EDT) moderate Resolution Imaging Spectroradiometer or MODIS instrument abroad NASA’s Aqua satellite saw Tropical Cyclone Fantala off Madagascar. MODIS instrument revealed a 16 nautical-mile-wide eye surrounded by powerful ring of convective thunderstorm. Image indicated by MODIS also showed powerful thunderstorm wrapping into center from northern and southern quadrants of storm.

Surface wind speed is always lower than speeds at higher altitude. 

Tropical Cyclone Fantala was located at the tip of Madagascar and about 783 nautical miles of northwest of Port Louis, Mauritius and city of Antsiranana north of Madagascar. Eye was centered near 9.3 degree south latitude and 49.7 degree east longitude.

Maximum sustained winds were near 150 knots (172 mph/ 277.8 kph) and hurricane force extended 25 miles winds which are powerful (28.7 miles/46.3 km) from center, tropical storm force wind extended 100 miles (115 miles/185.2 km) from center too.

Factor of changing Fantala

The factors steering Fantala are changing, but movement of Fantala was measure with 4 knots (4.6 mph/7.4 kph) which generate 40-foot (12.1 meter) high sea level.

There is a change in forecast direction of the storm, and steering of Fantala mechanism is beginning to shift from-latitude positioned to the south to a building near-equatorial ridge to the north Fantala.

According to Joint Typhoon Warning Center forecasters, Fantala will turn on a southeasterly course and begin moving in that direction slowly weakening and by April 22 storm will steer toward northeastern Madagascar.
