Explanatory notes:
Weak southwest conditions during the weekend.
06Z MSLP analysis shows a weak tropical low over the Western Pacific to the west of Southern Philippines.This tropical low likely strengthens next week along with the monsoon trough with Tropical Storm Roke and a tropical depression embedded within over northern South China Sea and will lead to moderate to strong strong southwest monsoon conditions over the region but still some uncertainty.
Forecast gives more weightage to the ECMWF model than the GFS model.
