NWS VTEC Event ID Usage
This page provides a listing of VTEC events for a given forecast office or state and year. There are a number of caveats to this listing due to issues encountered processing NWS VTEC enabled products. Some events may appear listed twice due to quirks with how this information is stored within the database. Hopefully, you can copy/paste the table into your favorite spreadsheet program for further usage!
This listing provides two links to find more information. The "Event ID" column provides a direct link into the IEM VTEC Browser and the "HVTEC NWSLI" column provides a direct link into the HML Obs + Forecast Autoplot application.
There is a JSON(P) webservice that backends this table presentation, you can
directly access it here:
