What Is Damage Survey?

In technical terms: A post-event field (and increasingly aerial or satellite) assessment by NWS meteorologists documenting damage indicators and degrees of damage, path length and width, and damage patterns (convergent versus divergent) to assign an EF rating and classify the event.
