Stormwise

One answer in a flood: what should my household do next?

geospatial · Next.js · risk · Bengaluru

Weather apps describe the sky. Disaster dashboards describe the city. Stormwise closes the gap between them: it combines live rain forecasts, terrain, river-catchment discharge, curated flood hotspots, and your actual commute into a single answer — what should this household do, right now.

The wedge is a personal flood digital twin. The same storm means different things to a high-floor apartment, a ground-floor home, and a two-wheeler commute through an underpass; Stormwise scores the difference with real OSRM routing, segment-level elevation, Open-Meteo forecasts, and Copernicus GloFAS discharge signals, with Gemini-backed plans held to strict Zod output contracts.

It launches deliberately deep in Bengaluru rather than shallow everywhere — risk communication without locally curated drainage context creates false confidence, and false confidence in a flood product is worse than no product. Onboarding runs in sixty seconds, in English, Kannada, and Hindi, with no account: the household profile lives in the browser.
