Explanatory notes:
06Z MSLP analysis shows a tropical low over the northern South China Sea.The tropical weather system is expected to lie over the South China Sea tomorrow leading to moderate southwest monsoon conditions until the southwest monsoon weakens during the weekend.The southwest monsoon likely strengthens again early next week with the development of a tropical system over the Western pacific but still some uncertainty.
Forecast gives more weightage to the ECMWF model than the GFS model.
