Tropical Disturbance 93w gains more strength as it moves toward Vietnam...94w slightly organized during the past 6 hours






Tropical Disturbance 93W
  • 14.8N 111.6E
  • 220 km NE of Nha Trang City, Vietnam
  • now currently over South China Sea
  • maximum sustained winds: 37 kph
  • minimum sea level pressure: 1006 mb
  • currently moving westward @ 24 kph
Based on the latest satellite imagery, there is a probablity that tropical disturbance 93w now over South China might develop an active cyclone within the next 12-24 hours. However if that would be the scenario, it would be a weak-strong tropical depression based also to it's exact location/environment and speed. Latest numerical weather guidance model also shows the possible formation of active disturbance near Vietnam. This active disturbance might dump moderate to heavy rainfall as it forecasts to move Central/Northern Vetnam with in the next 12-24 hours.

Tropical Disturbance 94W
  • 18.7N 124.5E
  • 450 km ESE of Basco, Batanes
  • now currently over Northern Philippine Sea
  • maximum sustained winds: 28 kph
  • minimum sea level pressure: 1008 mb
  • currently moving WNW @ 20 kph
Latest satellite imagery shows an organized circulation slightly during the past 6 hours. The chances of becoming an active disturbance has increases to 50% as weak diffluence in the upper levels and light vertical wind shear support a possible organization as it moves in to Northern Luzon. The said system is emedded along the dominant weather system that affecting the country which is the Inter-Tropical Convergence Zone. Latest numerical weather guidance model,GFS, forecats this system to develop once it transverse Northern Luzon or over Northern South China Sea.
