Tropical Storm Claudia (03S) Expected to Strengthen4.2S 76.8E
Tropical Storm Claudia (03S) located approximately 480 nm south-southeast of Diego Garcia, has tracked southward at 05 knots over the past six hours.
Satellite imagery reveals a mature tropical cyclone with a well-formed eye that has now expanded to approximately 15 nm in diameter. The intensity is assessed at 105 knots. Maximum significant wave height is 34 feet.
Upper-level analysis indicates Claudia is in a favorable environment, nearly under the sub-tropical ridge axis with weak (05-10 knots) vertical wind shear (VWS) and a robust poleward outflow channel. These favorable conditions are forecast to remain in place for the next 24-36 hours, after which rapidly decreasing SST values and increasing VWS associated with a deepening trough to the west will start to weaken the system.
By TAU 72, TC 03S will begin extra-tropical transition as it interacts with the baroclinic zone poleward of 25 degrees south. Extra-tropical transition will be complete by TAU 96.
