Anja has continued to weaken over the last 24 hours, and NASA's QuikScat satellite has confirmed that the once mighty Category 4 Cyclone is now a tropical storm in the southern Indian Ocean. Two instruments on NASA's Aqua satellite have also helped forecasters determine Anja's location and change of shape.
NASA's QuikScat satellite uses microwave technology to peer through a tropical cyclone's clouds, and actually read the speed of the rotating surface winds. In an overpass from space at 7:58 p.m. ET last night, November 18 (Nov. 19 at 0058 UTC), QuikScat noticed Anja's maximum sustained winds have dropped to 63 mph, making it a tropical storm
