Heavy rainfall, flooding and landslides has left at least 2 dead and 1 missing in Kumamoto prefecture Western Japan this Tuesday morning.

 

Kumamoto is the location of last months massive earthquake that damaged hundreds of homes across the city.  This also left the ground unstable leaving it prone to landslide in the event of additional aftershocks or heavy rainfall.

During the overnight hours Monday in to Tuesday extremely unstable conditions that evolved off a pulse of energy with the rainy season front surged over Kyushu bringing up to 150mm of rainfall in just one hour. This was a recording breaking rain total for this location in Kumamoto.

Rivers across Kyushu are also in danger of flooding, this has prompted evacuation advisories for over 1,000 people on the island.

Good news is for Kumamoto the rainfall has stopped for the rest of Tuesday, BUT southern Kyushu still could see an additional 150mm with up to 120mm in parts of Shikoku through central Honshu.

Storms are expected to kick back up in Kumamoto once again by Wednesday morning though, so only a little bit of a break for the city. The city is already fairly prone for landslides so the additional rainfall will put the area at even higher risk. The image below is the landslide threat map as of Tuesday morning.
