Meteosat-7 Infrared Window (11.5 \u00b5m) images [click to play animation]<\/p><\/div>During the 17-18 April period Cyclone Fantala reached Category 5 intensity (ADT plot<\/strong><\/a>), with maximum sustained winds of 150 knots (making it the strongest tropical cyclone on record in the South Indian Ocean); Fantala also became the longest-lived hurricane-strength tropical cyclone on record for that ocean basin. Meteosat-7 Infrared Window (11.5 \u00b5m) images (above)<\/strong><\/em> showed the storm reaching peak intensity as it moved just north of the island of Madagascar.<\/p>\n
