Locationpresent25/25
Final assessment
Last seen at campus Parking T; last reported remaining in the recinto.

Impactpresent25/25
Final assessment
A female student, not named; mother is the reporting person.
What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
