JP Weather Map

Rain & Wind Weather Map is a weather forecast map for users whose work or equipment is directly affected by weather—such as construction sites and outdoor operations.

"What will the rain and wind be like at the site?" "Check cloud/rain movement for solar power." "How hot will it get during today's work?" "Plan site work and deliveries days ahead."

View changes in rain, clouds, temperature, wind, and pressure on the map. Main Features ■ Weather data on the map Uses latest NOAA GFS global numerical model data, rendered for Japan and surrounding areas. Displayable elements (switch via top buttons):

Rain: precipitation intensity Clouds: cloud cover Temperature: near-surface air temperature Wind: near-surface wind speed Pressure: sea-level pressure

■ Nationwide to regional views

Japan (full) / Japan (excl. islands) Hokkaido, Tohoku, Kanto, Hokuriku, Tokai, Kansai, Chugoku, Shikoku, Kyushu, Okinawa

Zoom in regional views to check around your work site or facility. ■ Time-series animation Play forecast data continuously for the selected day.

Play/Pause, previous/next, time slider Auto-stops at the final forecast time

Visualize rain/cloud movement and changes in temperature/wind. ■ Up to 16 days ahead

Up to 5 days (120h): every 1 hour 123h to 384h (16 days): every 3 hours

Current day starts near present time; following days from 00:00. Ideal for short-term decisions and long-term scheduling. ■ Quick date selection Tap forecast dates at the top to switch days instantly. Typical Uses

Construction/civil engineering scheduling Outdoor inspections, maintenance, surveying Material delivery & heavy equipment planning Solar power cloud/rain monitoring Farm work and outdoor events Heat/wind impact assessment Travel weather trends

Data Source Directly fetches GFS 0.25° grid data from NOAA/NCEP NOMADS (no intermediate servers). GFS is a global model suitable for broad patterns and multi-day forecasts. Important Notes App data is based on numerical predictions and not official forecasts from the Japan Meteorological Agency. 0.25° resolution may not capture fine local terrain effects or sudden changes. For critical decisions (work, safety, evacuation), always combine with official JMA forecasts, warnings, radar, and local authority information. Retrieval may be delayed due to data updates, NOAA status, or network conditions. Check site weather changes with Rain & Wind Weather Map via maps and time animation.
