>>> There’s an area of disturbed weather being referred to as Invest 98W…which is located approximately 259 NM east-southeast of Yap
Animated enhanced multi-spectral imagery (msi) depicts a slowly consolidating low level circulation center (llcc).
Environmental analysis for the area indicates favorable conditions for development with low vertical wind shear (5-10 kts), warm sea surface temperatures (30-31 c), and good poleward outflow.
Global deterministic models show 98W intensifying over the next 36-48 hours with gfs being the more aggressive model. While global ensembles are in good agreement on gradual development as it transits along a westward track.
Maximum sustained surface winds are estimated at 12 to 18 knots.
The potential for the development of a significant tropical cyclone within the next 24 hours remains
