Western Pacific
>>> There’s an area of disturbed weather being referred to as Invest 93W which is located approximately 139 NM east-southeast of Legazpi
Animated enhanced infrared satellite imagery (eir) depicts deep convection building near the consolidating low level circulation center (llcc). A 051346z ascat reveals 15-20 knot winds starting to consolidate along the western periphery.
Environmental analysis for the area indicates marginally favorable environment with high vertical wind shear (20-30 kts), warm sea surface temperatures (29-30 c), and good poleward outflow aloft.
Global deterministic models are in good agreement that 93W will move west over the Philippines. Global ensemble models are in good agreement that 93W will move west over the Philippines, with ecens showing a higher intensity between the two models.
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 remains high.
