Discussion:

Himawari-9 visible satellite image (Weathernerds), showing a diffuse circulation moving over Hokkaido

Not long after the first advisory, the convection associated with Tropical Storm 08W rapidly dissipated, and its circulation started losing definition. There is still a low-level circulation present, quickly moving over Hokkaido, but it is very poorly defined and difficult to discern on satellite and radar imagery. Given the extremely hostile environment of strong shear and very cold SSTs (less than 12°C), and the fact that the already poorly-defined circulation is quickly headed for more rugged terrain, it seems likely that 08W won’t be a distinct entity for more than a few hours, so this is the last advisory.

This is the last advisory on 08W.
