Following landfall early on Wednesday, Etau continues to bring heavy rain to parts of Honshu. However, it will weakening through the end of the week.
Etau formed south of Japan over the weekend and become better organized as it moved northward early this week.
This system made landfall just west of Hamamatsu, Japan early on Wednesday, local time, and then exited into the Sea of Japan Wednesday evening. Periods of heavy rain extended as far eastwards as Tokyo, bringing soaking rains.

Some places saw too much rain. As of 9 p.m. on Wednesday, Nikko, Japan had 249 mm (9.8 inches) of rain, causing flooding throughout the region.
By the time rain is said and done on Thursday, some locations could have as much as 300 mm (12 inches) of rain. As all of this water rushes off the mountainous terrain, flooding will become a significant concern as well as the threat of mudslides.

As Etau slowly moves northward away from Japan, the system will continue to weaken. Through the end of the week, a few lingering showers could be possible across central Japan, but the flooding threat will diminish. Any wind threat will be long gone by that time.
Rainfall during the second half of the week is expected to lessen across much of Japan, though additional rainfall could still lead to isolated flooding problems in northern Honshu on Friday.

Meanwhile, Tropical Storm Kilo will approach Japan before turning northward from Friday into the weekend. This track will take Kilo close enough to Hokkaido that the outer bands of the storm could bring downpours to eastern Hokkaido.
Residents along the western Pacific Ocean should be on the watch for additional tropical threat through the fall, according to AccuWeather's Fall Forecast for Asia.
