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.

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.
