Current Weather forecast for Japan Fukushima region:
Today there are only local rain showers. The wind was blowing moderately, partly to life in coastal areas from southeast to southwest.
Spreading from the southwest part from heavy rain that can bring large amounts of rain. Also, thunderstorms are in the process. The wind blows from the southeast to southwest lively temporarily, after front passage increases from southwest to west. Small Leetiefs on the east coast of Japan may in the troubled region but the wind can blow at times also from northeast to southeast - and from the Pacific.
It is anticipated an interim improvement. Only in places there are rain showers in many places it is dry and the wind will come back weaker and increasingly from south to southwest. (Especially for the Tokyo area). To the nuclear power plant there can be temporary but light winds from the northeast to southeast.
Plumes / dispersion calculations
Please note that the radiation exposure decline in the crisis region. The effects of the accident have been reduced so significantly.
The color scale shows a total of five colors. , Area A "(purple) is meant to mark in area with maximum dose rate of 0.3 ╣ Sv / h, Which Corresponds to the amount of natural background radiation dose." Area B "(blue) marks a region with 3 micro-Sievert per hour. Finally, one arrives in "Area E" with a maximum dose rate of 3 milli-Sievert per hour. This dose rate is currently certainly not exceeded in the regional area (25x25 km 2 box) around the NPP. Irrespective of the assumed emissions, the maximum value of the model is always used to Determine "Area E".
Please keep in mind that, due to the decreasing level of radioactivity in the crisis region, the actual area of influence is likely much smaller than the one Displayed here.

Latest NEI UpdatesUPDATE AS OF 12 P.M. EDT, FRIDAY, APRIL 22: Below is a round-up of noteworthy news that happened this week with regard to the Fukushima Daiichi nuclear plant and the U.S. nuclear industry's response.
- Tokyo Electric Power Co. (TEPCO) released a roadmap to bring the Fukushima Daiichi nuclear plant to a stable condition.
- Priorities at Fukushima this week continue to be cooling the reactors and spent fuel pools, draining water from the turbine buildings and concrete structures that house piping to reduce radiation levels, and containing the spread of radioactive materials.
- Overall, site radiation dose rates are stabilizing. The most recent radiation readings reported at the plant site gates ranged from 5.7 millirem per hour to 2.6 millirem per hour.
- Japan's government has expanded evacuation to selected areas outside the original 12.5-mile zone. Authorities also are barring entry into nine municipalities near the plant.
- TEPCO released a presentation on April 18 summarizing the impact of the earthquake and the current status of the plants.
