atticuscornett/AtmosWeather ? reverse-engineered prompt

Build me a lightweight weather app called Atmos Weather that works on the web, desktop, and Android, for people in the US. It should show current forecasts and weather alerts using the official National Weather Service data, and it should feel simple, fast, and not cluttered. I want users to be able to choose one or more locations, get alerts for each one, and control which alerts matter most. For weather warnings, don’t just show plain text, also make it easier to understand with a map style view of the warning area and include the official instructions and details.

Keep the design clean and minimal, and make sure it works well across screen sizes. If you need to, look up current docs online to make sure the setup and platform pieces are done the right way. Also keep privacy in mind and avoid collecting anything unnecessary.
