How the first alert is built
To check this alert, SuperGrok Heavy 4.5 (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.
URGENT CU ALERT: High Wind Warning has been issued for the Clemson area until 9:30PM. Possible gusts up to 55 mph. Seek shelter.
Sourcepresent25/25
Final assessment
All 25 reads find Source present because the branded signature CU ALERT (often with URGENT) identifies who is issuing the message.
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.

Hazardpresent25/25
Final assessment
All 25 reads find Hazard present: a High Wind Warning, often with possible 55 mph gusts, names a specific weather threat.
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.

Locationpresent25/25
Final assessment
All 25 reads find Location present because the warning applies to the Clemson area, a named place.
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.

Guidancepresent25/25
Final assessment
All 25 reads find Guidance present: recipients are told to seek shelter, a direct protective action.
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.

Impactabsent2/25
Final assessment
23 of 25 reads find Impact absent: gusts up to 55 mph describe wind strength, not harm; 2 treat the speed plus warning as severity.
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.
