Tropical Cyclone Felleng (13S) Tracking South at 14 Knots25.7S 50.6E
Tropical Cyclone Felleng (13S), located approximately 370 nm southwest of La Reunion, has tracked southward at 14 knots over the past six hours.
Animated multispectral satellite imagery shows the system has begun to show signs of elongation as the main convective bands are displaced eastward of the low level circulation center. This is also readily apparent on a 37ghz SSMIS microwave pass.
The initial position is based on the above animation and on the SSMIS image with high confidence. The initial intensity is based on congruent Dvorak estimates from PGTW, KNES, and FMEE. Upper level analysis indicates the system is south and west of a ridge axis in an area of moderate to strong (20-30 knot) westerly vertical wind shear (VWS).
