Tropical Storm Danas has brought torrential downpours mainly to western Japan. Forecasts show that heavy rain could hit wide areas of the country through Saturday.
The Meteorological Agency says Danas is moving north over the East China Sea at 20 kilometers per hour, as of 3 a.m. Friday morning. It is packing winds of 83 kilometers per hour.
The agency says winds of up to 72 kilometers per hour will hit Okinawa and northern Kyushu through Saturday. Waves are expected to reach up to 7 meters high in waters off Okinawa Prefecture and northern Kyushu.
Danas has been sending warm and damp air toward a rain front extending across the country. As a result, there have been intermittent downpours mainly in western Japan.
In Tsushima City, Nagasaki Prefecture, 52 millimeters of rain were recorded during a one-hour period early Friday morning.
Atmospheric conditions are expected to remain unstable through Sunday in Okinawa and western Japan, and through Saturday in eastern Japan. Some areas could receive more than 50 millimeters of rain per hour.
Weather officials are warning of landslides, swollen rivers, and flooding in low-lying areas, as well as lightning and gusty winds.
