g-aaditya/Cloudburst-Early-Warning ? reverse-engineered prompt

Build me a Streamlit app for cloudburst early warning in the Indian Himalayas.

I want it to let a user open an Excel file, edit weather input values in a sheet, save the file, and then see the app update automatically or with a reload button. The app should show cloudburst risk for the next 1 to 3 hours, plus simple impact estimates for flash floods, landslides, and runoff. Please include clear dashboard sections for the main prediction, a heatmap view, impact analysis, physics based indicators, explainable AI style feature importance, alerts, and a page that shows the Excel data and results.

Make it feel polished and easy to use, with charts and color coded risk levels. If you need to, look up current docs online for Streamlit and Excel file handling. Keep the structure clean so the prediction logic can live separately from the UI, and make sure the app can read from and write back to the Excel file.
