In the latest on life-threatening rains in western Japan...one man is dead and two others are without vital signs as weather officials warn residents to evacuate immediately. They've issued their highest emergency warning for three prefectures in Kyushu.
Saga, Fukuoka and Nagasaki are being drenched with heavy rain.
Evacuation orders and advisories have been issued to about 1.6 million people across the country.
Parts of Saga Prefecture were hit with more than 100 millimeters of hourly rainfall. And the rain is expected to continue.
A video posted on Twitter shows water seeping into a bus with passengers on board. It was en route to Saga airport.
Rescue officials in one city in the prefecture say they have received many calls from people either trapped in their cars or unable to evacuate because of flooding.
About 40 members of Japan's Ground Self-Defense Force are being dispatched to help with rescue operations.
The deadly rain has killed one man in Saga after he was found without vital signs in a washed away car. A woman in the prefecture and a man in Fukuoka Prefecture, were also found without vital signs. Some riverbanks have flooded. There were also reports of mudslides.
Yasushi Kajihara of Japan Meteorological Agency says, "It's highly likely that some sort of disasters such as landslides or flooding may have already occurred, especially in areas with mudslide warnings or in other hazardous places expected to be inundated. These areas are under alert Level 5, which requires people to take immediate action to protect their lives."
Transportation is also disrupted.
Train services are partially suspended in northern Kyusyu.
Expressways are also partially closed in several locations.
