Track of TC 21S

Tropical Cyclone Imelda (TC 21S), located approximately 650 nm north-northeast of La Reunion, has tracked west-southwestward at 13 knots over the past six hours. Maximum significant wave height is 22 feet.

The initial position is based on recent animated multispectral satellite imagery. The initial intensity is averaged from subjective Dvorak estimates from multiple reporting agencies. Animated infrared satellite imagery shows deepened convection over a low level circulation center that is beginning to form into an eye-like feature.

TC 21S lies slightly equatorward of an upper-level ridge axis, in an area of moderate (15-20 knot) easterly vertical wind shear (VWS); however, animated water vapor imagery shows excellent radial outflow.
