Francisco has made a sharp turn toward the northeast which will keep the center of the storm off the coast of Japan. However, it will still bring heavy rain and a risk of flooding to part of the nation.
Although the tropical storm has been following a track similar to deadly Typhoon Wipha from last week, Francisco will pass farther offshore and produce only a limited wind threat for eastern Japan.
The greatest threat from Francisco will be the heavy rainfall that will continue into Saturday before ending as Francisco is pulled farther northeast into the open Pacific Ocean.
Thus far, the heaviest rainfall has occurred across Shikoku and southern Honshu, where many locations have received 150-250 mm (6-10 inches) of rainfall. One of the hardest hit areas is Kochi, where rainfall has totaled 313 mm (12.32 inches) through Friday evening, local time.
Across the Tokyo metropolitan area, one of the hardest hit by Typhoon Wipha, rainfall totals between 25-75 mm (1-3 inches) are forecast through Saturday night. The heaviest rainfall was still off to the south and west of Tokyo Friday evening, local time, but a soaking rainfall is expected from later Friday night into Saturday.
In eastern Kyushu, Oita recorded 217 mm (8.54 inches) of rain. Morotsuka has seen a extremely high amount of rainfall, reaching 381 mm (15 inches). The major city of Fukuoka in northern Kyushu has had 151 mm (5.95 inches) of rainfall.
The rainfall from Francisco will cause many areas across southern and eastern Japan to reach 200-300 percent of their normal monthly rainfall for October.
