Kirk here. Thanks, William, for the link to the JMA page that shows an assortment of data on expected rain and wind in Kumamoto. It wasn’t easy but I was able to find an English version of the same data:
https://www.jma.go.jp/bosai/#lang=en&area_type=offices&area_code=430000&pattern=rain_snow
Currently, in cases like this, one has to go to top page and begin a new search for the relevant information. It would be nice if the JMA (Japanese Meteorological Agency) would provide links from Japanese pages directly to foreign-language counterparts like this. Over the years, however, I’ve learned that many public agencies in Japan assume that Japanese-language pages are only referred to by Japanese people and that there’s no need to link from a given Japanese page to its English counterpart. Sigh . . .
