Plot Description:

This chart displays the relative frequency of VTEC products. This is computed by taking the unique combination of events and UGC county/zones. Restating and for example, a single Severe Thunderstorm Warning covering portions of two counties would count as two events in this summary. The values plotted are relative to the most frequent product.
