TS Talas and TS Noru Update

Tropical Storm Talas is now losing tropical characteristics as it moves over the Sea of Japan. Both the JTWC and JMA have released final warnings for this system. Talas is bound to become a weak extra-tropical cyclone within the next 24 hours. The storm center was last located approximately 400km west of Aomori in the Tohoku Region. Talas is moving northward at 30kph.

Rain has ended now across much of Shikoku, Kansai/Kinki, and Chubu Regions. So far, reports indicate that as many as 25 have already died due to Talas and more than 50 people are still missing. Fortunately weather should gradually improve and rivers should begin to recede from flooding stage.

Talas is still bringing rain, however, across extreme Northern Honshu and Hokkaido. We are expecting rainfall amounts of 100 to 200mm in the next 24 hours.

This will be our final update on Tropical Storm Talas.

Another system that we are watching is Tropical Storm Noru which is located approximately 940km east northeast of Tokyo. Maximum sustained winds are at 65kph gusting to 95kph. Noru is moving northward at 30kph.

TS Noru will continue weakening as it encounters increasing wind shear and cooler waters to the north. It is also expected to begin extra-tropical transition within the next 12 to 24 hours. Noru is not forecast to approach Japan although it could move towards the Kuril Islands (Russia) within two days.

As for the rest of the Pacific, we have a tropical disturbance that has been spotted east of Luzon; located more than 1,000km away. An ASCAT pass earlier shows a weak but closed low-level circulation. IR image is also showing some weak convective activity in and around the center. This Low-Pressure Area has almost no model support for development and JTWC is giving it just a "LOW" rating for cyclone development. Nevertheless, the system is in a somewhat favorable region for development so we will definitely continue watching this.


Unfortunately, I haven't had enough time recently to put up Video Updates regularly. If you still want to watch Videos regarding the Western Pacific Typhoons, you can head to Meteorologist Robert Speta's YouTube Channel for his latest analysis just like what I do here. Just click HERE

I will still put up Video Updates from time to time, especially when a cyclone is threatening the Philippine Islands.
