UPDATE: The Low Pressure Area (LPA 07a; US: Invest #97W) has been upgraded by @dost_pagasa to a MEDIUM chance of tropical cyclone development within the next 24 hours. Meanwhile, the Japan Meteorological Agency (JMA) has already classified the system as a tropical depression. ⚠️A decent westerly outflow is supporting the disturbance's convective activity, with a favorable upper-level environment for further development. However, its elongated structure is hindering gradual consolidation, and mod

The global models are now in consensus that the tropical disturbance (US: Invest #95W) in the Marshall Islands could become a significant typhoon by late next week into the following week over the west-central Pacific Ocean.Japan's GSM model is the most aggressive, showing a central pressure below 920 hPa — which is rare for that model. This is equivalent to the "violent" category on the JMA scale. The model has been consistent over the past three days.Meanwhile, the other global models (GFS, EC
