Absolute Vorticity

The only item on the board today is TS Yun-Yeung. This one is expected to remain a TS and potentially brush the Eastern Japanese Coast (including Tokyo) as it moves NE.

TS Yun-Yeung.is expected to impact the Eastern Japanese coastline and cities in a few days passing west of Tokyo and then dissipating over the northern mountains.

TS Yun-Yeung.is now down to a depression and 94W and 90W both are new waves that have a low chance of development.

Wave 96W has a low chance to develop at this time.

96W now has a medium chance of development.

96W has been downgraded back to a low chance of development.

Only thing on the board right now is wave 91W, which has a low chance of development.

91W now has a high chance of development with 92W having a low chance.

92W still has a low chance to develop, however, 91W is now TD 13W. This depression looks to have a shot lifespan as it moves NW and eventually W into SE Asia over the next few days.

TD 13W has made landfall in SE Asia and will dissipate over the next day or so.

Only 1 item on the board right now which is Invest 93W and it has a low chance of development at this time.

93W now has a high chance of development.

We currently have TS Koinu which will become a typhoon shortly. This one is expected to move NW and potentially clip S Taiwan in the coming days then turn more West to possibly impact mainland China as well.

Typhoon Koinu will move over S Taiwan in the coming days and eventually weaken over Mainland China this weekend.

We can just about say goodbye to TS Koinu as it continues to weaken as it moves into China. We now have TS Bolaven to keep an eye on. It is expected to become a typhoon then recurve off of Japan. This could assist in keeping our +PNA pattern going in the Eastern US.

We now have Super Typhoon Bolaven which is still forecast to do the recurve.

Bolaven is back down to typhoon status as it recurves NE of Japan with its leftovers becoming extra tropical as it heads NE towards the Bering Sea in a few days.

99W has a high chance of development.

We have TS Sanba on the board and this one is expected to track towards SE Asia.

Sanba is weakening today and is already a remnant low.

We finally have something on the board now... Wave 95W has a low chance of development.

In addition to 95W, we also have 96W and 91P. All three have a low chance of development.

We now have TD 17W. This system is expected to become a TC and impact the Philippines in the coming days. We also have TC Mal. This one is dropping SE and impacting some of the Pacific Islands North of New Zealand.

TD17 W is now weakening and we can almost take that one off the board. TC Mal is still dropping to the SE and will stay east of New Zealand. We also have 97W now which has a low chance of development.

TC Mai is weakening and we can almost take this one off the board. 97W is gone now but we have a new wave 98W which has a low chance to develop.
