Western Pacific

>>> There’s an area of disturbed weather being referred to as Invest 99W, which is located approximately 40 NM southwest of Yap

Animated multi-spectral (msi) and enhanced infrared (eir) satellite imagery depict a broad low level circulation center (llcc) with persistent convective banding along the southwestern periphery. The llcc remains ill-defined, and earlier microwave imagery and high-resolution model data suggests a misaligned vortex, which is inhibiting more rapid development.

The current intensity is assessed as 25 kts, however the wind field is highly asymmetric, and the 25 kt winds are currently limited to a more linear flow along the southern periphery of the circulation.

Environmental analysis reveals a favorable environment for development with moderate equatorward and poleward upper-level outflow, low deep-layer wind shear (10-15 kts), and warm sea
surface temperatures (29-30 c).

Global ensemble and deterministic models show 99W tracking generally northwestward as it continues to undergo consolidation and intensification over the next 24 hours.

Maximum sustained surface winds are estimated at 23 to 26 knots.

The potential for the development of a significant tropical cyclone within the next 24 hours remains high.
