It looks like the storm will come fairly close to Kumamoto around Wednesday or so but, fortunately, it will probably be considerably weaker by that time. The yellow color indicates that it will probably be a Category 1 typhoon (according to the site’s categories), down from a much, much nastier Category 4.
