Good question. We have been using polygon alerts instead of counties for 5 or 6 years now. We only alert the zip codes within the polygon.

Great. Nice to know! Definitely more accurate than the "old alerts".

Chris S, do you have an update? I haven't heard anything from our teams yet. I know people are eager to try it. :-)

Polygram alerts seem better and effective imo.

i'm just shocked how any programer can make them set up properly with the latitudes and longitudes polygrams...

I think we're using Zip Codes, but Lat/Lon has been done in some apps!

I've been doing "distance from my location" given lat/long for lightning warnings for over 10 years.

If you're not worried about precision to fractions of a percent, it's only a couple of lines of code if you have "event lat/long" and "observer lat/long".

wow zip code alerts....lots of programming there in my view...zip code/lat-long is ok to me.
