terms that are actually secondary event terms that are often mistaken as a primary event term. (i.e. “thunderstorm warning”).

The term “thunderstorm warning” is a secondary event term that refers to the act of responding to a warning, not the real or anticipated presence of a thunderstorm event itself. With all possible secondary event terms making a long list of terms, it makes it difficult to manage a list of terms for comparison purposes. Furthermore, such secondary events are not what the CAP elements, <severity>, <onset>, etc. were designed to address, although many authorities just use a value representative of the primary event. However, in this case, the primary term “thunderstorm” will suffice as it makes comparisons and list management easier.
