Tropical Cyclone Haruna (16S) Maintaining Large, Symmetrical Eye
Tropical Cyclone Haruna (16S), located approximately 285 nm southwest of Antananarivo, Madagascar, has tracked eastward at 06 knots over the past six hours. Maximum significant wave height is 30 feet.
Animated infrared satellite imagery shows the system maintained a large and highly symmetrical 50-nm eye. The initial position is based on the above animation and from an AMSU-B microwave pass with high confidence.
The initial intensity is based on congruent Dvorak estimates from PGTW, FMEE, and KNES. Upper level analysis indicates the system is just to the west of an anticyclone in an area of low (05-10 knot) vertical wind shear (VWS) and excellent radial outflow.
