Getting old alerts

[Shom770]

I'm not able to retrieve alerts issued a month or so again via the /alerts endpoint. I was intending to get the polygon of all the snow squall warnings issued on 2/19/22, though the /alerts endpoint returns nothing for that day. How would I go about getting the polygons?

The API has between 14 and 30 days of previous alerts. Beyond this timeframe you can use Iowa State's database to get the polygons for specific events and dates. https://mesonet.agron.iastate.edu/request/gis/watchwarn.phtml Some of the data goes back to 1986. And they've done a nice job of homogenizing it so the data that you get out is consistent even though how the products have been presented has changed over the years.
