Track of TS 09S

Recent scatterometer data on Tropical Cyclone Emang (09S), supports a 30 to 35 knot system with the strongest winds over the southern semi-circle, enhanced by the subtropical high. Due to the lack of convective structure, Dvorak intensity estimates have decreased to 25 to 30 knots; however, the initial intensity is assessed slightly higher at 35 knots.

TC 09S is located within a marginal environment, under convergent upper-level flow, which is inhibiting convective development, and is embedded along the northern periphery of the subtropical high. Emang is forecast to continue weakening and should dissipate by TAU 12. The system will be closely monitored for signs of regeneration.
