Tropical Cyclone Imelda (21S) Dissipating12S 54.8E
Tropical Cyclone Imelda (TC 21S) is expected to struggle in maintaining its structure but will continue to track along the southwestern periphery of a near-equatorial ridge to the northeast.
Vertical wind shear (VWS) values are expected to increase as the system tracks poleward, contributing to the gradual dissipation by TAU 36. There is a distinct possibility that the cyclone will dissipate sooner. As the system weakens, the steering flow will begin to shift to lower levels. Available numerical model shows a large spread in the tracks, therefore, there is low confidence in the current track forecast. Maximum significant wave height is 18 feet.
