BB-1: Now lies as a Well Marked Low at 10.5N and 87.6E. Estimated Core pressure 1004 mb. Estimated winds at 15-20 knts.
The Positive Vorticity has increased over the South East Bay. MJO is in Phase 2 with amplitude 1. The TCHP ( Tropical Cyclone Heat Potential) is more than 100 kg/cm2 over the Southern Bay region, but decreasing in the North Bay. The SST is 30-31c. Upper Level divergence has increased.
Thus being favourable for the system. Initial Rapid Intensification.
