At 3:48 PM EDT on September 6, 2025, with Troy leading Clemson 7-0 and 10:43 left in the first quarter, officials suspended play at Clemson's Memorial Stadium ('Death Valley')) after lightning was detected within eight miles. More than 80,000 fans were directed out of the seating bowl as Clemson University Public Safety pushed an emergency alert instructing seekers of shelter to LJC, Fike, Brackett, and Sirrine Hall. Play resumed at approximately 5:20 PM EDT, a delay of about one hour and 32 minutes.

@ClemsonTigers on X (verbatim)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.
Lightning has been detected around Memorial Stadium. For your safety, if you are already inside the stadium, we ask that you please move to a safe location underneath the stadium. We'll keep you posted with updates! 📲
Final assessment
Unanimous agreement no sender or issuing authority is identified anywhere in the text.
Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.
Final assessment
Unanimous agreement 'Lightning has been detected' names the specific hazard.
What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.
Final assessment
Unanimous agreement the message names Memorial Stadium and the safe location underneath it.
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.
Final assessment
Unanimous agreement the instruction to move to a safe location underneath the stadium is protective guidance.
The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.
Final assessment
Most reads found no clock time or date, only implied present-tense detection; a few dissents read 'has been detected' as conveying recency, but the majority correctly treats that as no real timestamp.
When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.
Final assessment
Unanimous agreement no explicit statement of danger or consequence is given beyond the generic 'for your safety' framing.
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.
