Should Tropical Depression 23W become a named storm, it will be called Mirinae, a Republic of Korea (South) word meaning Milky Way. And somehow, PST believes they mean the galaxy, not the candy bar. :)

11:30 p.m. Japan time Sunday, Oct. 25: Tropical Storm Lupit continues tracking further east of the Tokyo area than forecast this morning, picking up forward speed and rapidly losing intensity as it traverses northeast at 20 mph toward cooler waters. Joint Typhoon Warning Center forecast calls for Lupit to swing 160 miles southeast of Yokosuka Naval Base at 3 a.m. Tuesday, packing sustained 46-mph winds and 58-mph gusts at its diminishing center. Wind parameters remain the same, 35-mph winds and 46-mph gusts forecast for Yokosuka by Navy weather service.

Unless the forecast track and intensity drastically changes, this is PST signing off for now.
