Enhancement: Alert targeting using FIPS zone alone results in false alarm potential #53

Problem: Using the NWS FIPS code results in monitoring relatively large geographic areas in some parts of the country. This results in the possibility of false triggers when the hazardous weather is not a threat to your location.

Here's a crude example of the issue I commonly encounter: image Yellow Star = Home Location (example only) Purple Box = FIPS Zone Blue Cloud = Storm System / Example Polygon Blue Arrow = Direction of storm travel (the assumption that future alerts would be issued along this path)

Potential Solutions: The NWS includes alert area polygon data in issued alerts. The NWS API also allows for point-based queries for severe threats. However, as others have pointed out in the Home Assistant Community, there are drawbacks to using this data/implementing a solution.
