Invest 98W

There’s an area of disturbed weather being referred to as Invest 98W, which is located approximately 140 NM east of Davao, Philippines.

Satellite imagery and a microwave image depict a poorly organized, yet fully obscured low level circulation with persistent deep convection on the northern and southern peripheries.

Environmental analysis reveals favorable conditions for further development, characterized by good upper level outflow, low to moderate
(15-20 knot) vertical wind shear, and warm sea surface temperatures.

Deterministic guidance is split on intensification with a small agreement on a general northwestward track over the next 48 hours. GFS shows invest 98W continuing westward over Mindanao, then a northward turn in the Sulu Sea, which is more plausible with the overall flow.

Maximum sustained surface winds are estimated at 18 to 23 knots.

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