aruchith08/GEOALERT-SIH-2026 ? reverse-engineered prompt

Build me a landslide risk monitoring web app for Meghalaya that shows live weather driven hazard updates on a map and gives clear alert levels for different areas.

I want the app to combine a static terrain risk score with changing rainfall and forecast data, then turn that into an easy to understand risk view for each location. The main screen should have an interactive GIS map, a way to switch between overall risk, terrain susceptibility, and rainfall driven hazard, plus a 7 day timeline so users can see how risk changes over time. It should also show a few key stations and a simple summary panel with Green, Yellow, Orange, and Red alert states.

Please make it work as a full stack app with a FastAPI backend and a modern Next.js frontend, and keep it polished and responsive. If you need current docs for weather or mapping tools, look them up online and wire it up cleanly.
