>>> There’s an area of disturbed weather being referred to as Invest 93W, which is located approximately 75 NM east of Puerto Princesa, Philippines.

Animated satellite imagery depicts flaring convection wrapping around a broad and disorganized low level circulation. Additionally, a broad circulation with 15-20 knot winds near the center and a swath of 20-25 knot winds to the north of the center, likely enhanced by funneling of low-level flow through the Philippine Islands.

93W’s environment has become increasingly favorable, characterized by moderate upper-level divergence, warm sea surface temperatures and low (5-15 knot) vertical wind shear.

Global models are in agreement that 93W will track generally west-northwestward over the next 24-72 hours. Although the environment is favorable overall, the weak low-level structure and interaction with land will likely continue to hinder development in the near-term.

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 medium.
