Update: Cyclone Claudio - South Indian Ocean
On Sun. Dec. 9, Claudia's maximum sustained winds were still near 100 knots (115 mph/185 kph). It was centered near 15.8 south latitude and 74.1 east longitude, or about 505 nautical miles south-southeast of Diego Garcia. Claudia is moving to the southwest at 4 knots (4 mph/6 kph) and is no threat to land.
On Dec. 9 at 2035 UTC (3:35 p.m. EST,U.S.) the MODIS instrument aboard NASA's Aqua satellite captured this infrared look at Claudia and revealed that the storm had a 10 nautical-mile-wide eye.
As Claudia continues south, it is moving into cooler waters under the threshold of 80F/26.6C needed to maintain a tropical cyclone. That means the cool waters will significantly weaken the storm (cooler waters do not evaporate and form the thunderstorms that make up a tropical cyclone as easily as waters 80F or higher).
