Rainfall Map around Fukushima Daiichi Nuclear Power Plant (Google Maps Tiling)

Rainfall data from the numerical weather prediction model GPV (meso scale model) by Japan Meteorological Agency at the surface level is visualized on Google Maps. You can see wind direction all over eastern Japan centered on Fukushima Daiichi nuclear power plant by Tokyo Electric Power Company. Moving the slider shows you the prediction of rainfall.

About Data

• The original data is obtained from numerical weather prediction model GPV (meso scale model, MSM). This is the result of weather simulation model, to some degree differing from the observed rainfall. The observation of rainfall is available at real-time AMeDAS rainfall map, and real-time radar rainfall.
• Data is updated every three hours, but with a little delay to display the latest information.
• Interval is one hour for the surface level, and three hours for other levels.
• Predictions are available for 15 hours at 3, 9, 15, 21 JST, and for 33 hours at 0, 6, 12, 18 JST. Predictions are overwritten when newer data is available.
• The latest data is shown at the beginning. To see predictions, move the slider to the right; to see past data, move the slider to the left. Clicking the time updates the latest information.
• The red marker shows the location of Fukushima Daiichi nuclear power plant. The circles shows distance from the plant, where the red circle represents 20km (evacuation zone), while the yellow circle represents 30km (indoor evacuation zone).

Time Series of Rainfall

Rainfall in the Last 72 Hours

The graph shows the time series of hourly rainfall and accumulated rainfall, where blue lines represent rainfall at AMeDAS Namie (approximately 10 kilometers from Fukushima Daiichi), purple lines, radar rainfall at AMeDAS Namie, and red lines, radar rainfall at Fukushima Daiichi Nuclear Power Plant. Because the radar rainfall does not represent the observed value, it may contain errors due to many factors. Please use it as a rough reference.

Forecast Rainfall

This graph illustrate hourly and accumulated rainfall around Fukushima Daiichi Nulcear Powre Plant from Meso Model GPV. This forecast is updated every three hours, and forecast rainfall will change frequently. Please check the latest information, and use it as a rough reference.
