NASA examines Category 5 Tropical Cyclone Fantala near Madagascar

Tropical Cyclone Fantala has become a major tropical cyclone in the Southern Indian Ocean reaching Category 5 status on the Saffir-Simpson Hurricane Wind Scale. NASA's RapidScat instrument observed powerful winds wrapped tightly around the eye, and NASA's Aqua satellite saw the well-structured storm with a wide eye as it was due north of Madagascar early on April 18.
