NOAA provides a free API to retrieve weather alerts, which this API uses. There is no registration required.
There are multiple ways to set the forecast area, and NOAA provides through documentation if you need extensive help. But the basics are

• By State: https://api.weather.gov/alerts/active?area={state}
• By Zone: https://api.weather.gov/alerts/active?zone={zone}
• By Lat/Long: https://api.weather.gov/points/{latitude},{longitude}
• By Grid: https://api.weather.gov/gridpoints/{office}/{grid X},{grid Y}/forecast

NOAA requires that a User-Agent header be provided. Please set your own custom agent in the config with unique contact information (the suggested header is: User-Agent: (myweatherapp.com, contact@myweatherapp.com) , so following that format makes sense.

This is still very much a work in progress. I have spent very little time styling it, and I haven’t even put together the README file yet (I’m going to steal this post, actually!). But I have had it running for the past 2 days with no major issues. So far I’ve only tested it in the top bar section. If anyone else wants to try it and provide feedback I’ll be actively improving it.
