Immediately after reactor 1 had hydrogen explosion on 3/12/2011, the wind direction forecast of meteorological bureau was concealed.
The Meteorological Bureau explained that this was because the rader station(s) were broken because of the earthquake, but the data was published later.
It was around Fukushima plants.
From the forecasting map, wind direction is completely removed like the picture below.
Also, though it snowed 15cm on 15th, weather forecast didn’t forecast it before hand.
Citizens therefore were left in 30km area without being informed of anything.
