Tropical Cyclone Eighteen (18S) Expected to Struggle at Moderate Gale Intensity13.9S 99.8E
Tropical Cyclone Eighteen (18S) is expected to struggle at moderate gale intensity over the next 48 hours with a distinct possibility of dissipation. After TAU 48, should the cyclone survive, decreasing vertical wind shear will contribute to a gradual intensification. The available numerical guidance are in overall agreement in eventually tracking the vortex eastward but with significant differences in track speed. Given the uncertainty in the steering mechanism, there is low confidence in the JTWC track and intensity forecasts. Maximum significant wave height is 17 feet.
