>>> There’s an area of disturbed weather being referred to as Invest 93W which is located approximately 323 NM east-southeast of Legazpi
Animated multi-spectral satellite imagery (msi) depicts a poorly defined low level circulation center (llcc) with weak convection associated with the llcc.
Environmental analysis reveals favorable conditions for development with low vertical wind shear (15 knots or less), good upper-level poleward outflow aloft, and warm sea surface temperatures (27-28 c).
Global models are in fair agreement that invest 93W will slowly consolidate as it tracks toward the central Philippines.
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.
