There’s an area of disturbed weather being referred to as Invest 91S, which is located approximately 399 NM west of Jakarta, Indonesia

Animated enhanced infrared (eir) satellite imagery and a 101520z metop-c ascat pass depicts a slowly consolidating low level circulation center obscured by flaring convection in the upper levels as well as elevated winds in the north-northwestern periphery of the circulation.

Environmental analysis reveals a favorable environment for development with low vertical wind shear (5-10 kts), warm sea surface temperatures (28-29 c), and good radial outflow.

Deterministic and ensemble models are in agreement on a steady development as it initially transits southeast along Sumatra and consolidating over the next 36-48 hours.

Maximum sustained surface winds are estimated at 23 to 27 knots.

The potential for the development of a significant tropical cyclone within the next 24 hours is upgraded to medium.
