Typhoon Ma-on brings heavy rain to Kochi

 

A large and strong typhoon is sweeping over the ocean off Shikoku in western Japan, bringing record rainfall to Kochi Prefecture.

 

The Meteorological Agency says typhoon Ma-on was 50 kilometers east-north-east of Kochi Prefecture and moving north-north-east at 15 kilometers per hour as of 6 PM on Tuesday.

 

Ma-on has a central atmospheric pressure of 960 hectopascals. Winds of up to 144 kilometers per hour are blowing near its center.

 

Developing rain clouds are bringing heavy rain to wide areas in western and eastern Japan.

 

In Kochi Prefecture, rainfall since Sunday totaled a record 1,000 millimeters.

 

The typhoon is expected to approach eastern Japan later in the day, affecting the region with strong winds and rain for a long time.

 

Thunderstorms and torrential rainfall of 50 to 70 millimeters per hour are expected in wide areas from Shikoku through Kanto-Koshinetsu region on Tuesday and Wednesday.

 

The agency warns that 80 millimeters per hour could be recorded in some parts of the Shikoku, Kinki and Tokai regions.

Radioactive water in Fukushima poses challenge

The Japanese government and Tokyo Electric Power Company will announce on Tuesday a revised plan to bring the reactors at the Fukushima Daiichi nuclear power plant under control.

They are expected to say that the first stage of the plan has been almost completed on schedule.

But a system to decontaminate radioactive water, which began operating at the end of last month, is working below the target capacity due to leaks and other problems.

The system’s decontamination rate dropped to 37 tons of water per hour at one point, more than 20 percent below the target capacity.

It increased to 39 tons per hour after TEPCO workers released air from the pipes on Friday. They also replaced a hose connecting the tanks to ease water circulation.

However, the rate dropped again to 37 tons per hour on Monday morning. TEPCO says the reason for the decrease is unknown.
