Power remains out at Clemson due to downed poles on Duke Energy transmission lines. Therefore, all Clemson University main campus day and evening classes and activities are canceled and offices are closed today, April 23. Employees: This closure, while weather-related, is an event in which leave will not be forgiven by the Governor. Employees must either: -take annual leave, or -take compensatory time, or -take unpaid leave, or -work with their supervisors to work from home or flex their schedules to make up time for today. Drivers: Many traffic signals are not working. State law requires that drivers treat non-working signals like stop signs and come to a complete stop before proceeding through the intersection. Check alerts.clemson.edu for updates.

Message elements

How the first alert is built

To check this alert, Claude (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

  • Impactpresent25/25

    Final assessment

    Present: I in first-burst CU Alert (clemson-university-weather-closure-2018-04).

    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.
