Tornado warning emergency alert later canceled

To check this alert, Claude Opus 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.

  Final assessment

  Present, 25 of 25. Two issuers are named: the "U-M EAlert" campus signature and "The National Weather Service in Detroit/Pontiac has issued a Tornado Warning".

  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.

  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

  Present, 25 of 25. The warning covers "Washtenaw County" and walks the storm path through Manchester, Chelsea, Dexter, Ann Arbor, Dixboro, Salem and Whitmore Lake.

  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

  Present, 25 of 25. It orders "Take cover now! Move to a basement or an interior room on the lowest floor of a sturdy building. Avoid windows."

  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.

• Impactpresent25/25

  Final assessment

  Present, 25 of 25, unanimously. A labeled Impact line spells out consequences: "Flying debris will be dangerous to those caught without shelter. Mobile homes will be damaged or destroyed."

  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.
