Tropical Update

 Tembin transitioned into an extra-tropical cyclone last night and is now moving across the Sea of Japan. All is quiet once again in the Western Pacific in terms of cyclone activity although we still continue to watch the basin for possible developments in the next few days.

While no tropical cyclone currently exists in the Western Pacific, we are watching a cluster of thunderstorms near Guam that might show sings of developing. This low pressure area, Invest 92W, is still in the early stages with disorganized and weak convective activity. Satellite analysis did show a closed, but weak, low-level circulation center west of Guam. 92W is not expected to develop in the time being but will be closely monitored for any improvements in structure.

Rest of the Western Pacific looks quiet with a weak Southwest Monsoon affecting the Philippines, enhancing showers and thunderstorms especially during the afternoon hours.

UPDATE: At 11am tomorrow (Saturday), Philippine Time, our affiliate Robert Speta from the Western Pacific Weather will be having a live webcast regarding the tropics. He will be joined by the renowned typhoon chaser James Reynolds. You can go to his YouTube channel tomorrow to watch the webcast and ask them questions regarding the tropics. Again, its tomorrow at 11am Philippine Time, 12pm Japan Time, or 03 UTC for those of you watching around the world.
