This page presents the number of VTEC events issued by either all of the NWS or a selected WFO. These numbers are based on the IEM maintained archive and are not official. Please be careful of the presentation of zeros, as some VTEC products were only recently added and don't go back prior to 2005. The IEM retrospectively assigned VTEC events to some warnings prior to implementation in fall 2005. Note: the numbers shown are the unique combinations of VTEC event ids and WFO, so a single tornado watch event issued by four WFOs would count as four in this summary, when summarizing all WFOs!

Hopefully, you can copy/paste this table into your favorite spreadsheet program for further analysis...
This information was cached within the past 24 hours and may not be up to the moment.

Option 1: All VTEC Events by Year

Option 2: Count of One VTEC Phenomena and Significance by WFO
