The area of convection (invest 93W) previously located near 12.2N 130.1E is now located near 11.4N 129.0E, approximately 323 nm east-southeast of Legazpi. Animated multispectral 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. Minimum sea level pressure is estimated to be near 1004 mb. The potential for the development of a significant tropical cyclone within the next 24 hours remains medium.
