STEERING WIND: Deep layered subtropical ridge over Northeast with an extension of the STR to the north
The system intensified into minimal tropical storm named Saudel means, Legendary Pohnpei Chief Soudelor's trusted guard/soldier (#PepitoPH) as it continues to endanger Aurora-Isabela area. Animated multispectral satellite imagery depicts a partially-exposed, slowly-consolidating system with broad convective banding wrapping into a ragged low-level circulation center (LLCC). Upper-level analysis reveals a favorable environment with near-radial outflow and low vertical wind shear as low-level environment remain conducive due to warm SST and High value of ocean heat content. TS Saudel is tracking west-northwestward along the southwest periphery of a deep-layered subtropical ridge (STR) positioned to the northeast with an extension of the STR to the north. For the next 24hrs (October 22, 1200pm), TS Saudel continues to track WNW with possible minimal intensification prior landfall over either areas of Casiguran, Aurora-Palanan-Isabela as entry point with 75-85km/hr maximum windspeed late this evening if speed wont change.
