Japan recovering after Typhoon Lan

Ben Domensino, Tuesday October 24, 2017 - 14:56 EDT

A storm brewing in the western Pacific Ocean threatens to hamper recovery efforts in typhoon-weary Japan.

Typhoon Lan made landfall in southern Japan on Monday, producing flooding rain, destructive winds and even snow down to sea level.

Lan was a super typhoon on the weekend as it drew energy from warm water in the Philippine Sea, with wind gusts near its core estimated to be around 300km/h. Fortunately, Lan weakened as it approached Japan on Sunday and made landfall as a low end typhoon early on Monday.

Despite weakening, the system was still producing destructive winds at landfall, although the standout feature for many areas was the rain.

The city of Owase in the Mie Prefecture of southern Japan recorded 495mm of rain during the 12 hours leading up to Lan's landfall. This was more than a month's worth of rain for this region. There were reports that some parts of the country's exposed southern coastline received around 800mm of rain during the course of this event.

The system also produced snow down to sea level as moisture and cold air wrapping into the decaying remnants of Typhoon Lan clashed into each other over the country's north.

The inclement weather from Lan has now passed, although there are indications that another low pressure system - possibly a typhoon - could threaten Japan later this week. While there is still a high degree of uncertainty regarding the future development and movement of this system, computer models indicate that heavy rain may start to affect flood-weary parts of southern Japan by Saturday.
