Fukushima Daiichi prepares for typhoon arrival
Tokyo Electric Power Company, or TEPCO, is rushing to put a makeshift roof over a turbine building at the Fukushima Daiichi nuclear power plant as typhoon
Ma-on approaches Japan.
TEPCO released a new photo on Sunday showing its preparation work.
The metal roof will cover the turbine building of reactor Number 3. The hole in its roof was caused by a hydrogen blast in March.
The new roof is 5-meters long and 16-meters wide. It is designed to cover up the hole to prevent an increase of radioactive water in the building.
TEPCO says the roof is scheduled to be installed with a crane on Monday.
Fearing high waves, a hose was temporarily disconnected from the "megafloat" barge, which contains relatively low-level radioactive water.
But no measures have been taken to prevent rainwater from entering reactor buildings 1, 3, and 4. The structures were damaged by hydrogen blasts.
However TEPCO says it does not expect any drastic increase of the water level in those 3 buildings.
At the Fukushima Daini nuclear power plant the doorway of reactor number 1 was also repaired to prevent rainwater leaks.

Forecast to be at Ashizuri Misaki, Shikoku tomorrow about 15:00 and at Shiomisaki, Wakayama on July 20, 15:00.
That would mean it passes us in the night from 19 to 20.
My roof is already boooming now from time to time, when a gale hits here.

Our regional weather report now shows this "rainstorm" icon for Wednesday, 20th.

Thursday might still be a bit less stormy.

The night was fairly quiet with some bouts of wind and rain.
When a storm bust strikes, the bamooo grove around us turns into a cloncking moving monster of sorts ... quite eerie to observe from my second-floor window.
And the main force is not here yet . . .

More than half of Japan is within the strong wind influence of the storm now.
Whow, and this is going to last for quite a while now.
Many trains not running, bridges closed, roads closed, airports closed, schools closed . . .
Our local train to Okayama is also not running.

Very big and strong typhoon is still hanging around Ashizuri Misaki, and might reach Kochi around 21:00 tonight. Tomorrow by 9 it might be in Wakayama.

The road in front of my home is littered with branches and leaves.
(I had to go out, the gasman was delivering a new load of gas. He said there are soooo many branches on the road, he is quite afraid, but has orders from his company to deliver.)

By tomorrow, we should be out of the strong wind zone.
