Weather reported with campus community notice washington advisory seattle

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. Bridge information is attributed to "SDOT" and quoted from "SDOT Traffic (@SDOTtraffic)", and the message points readers to alert.uw.edu.

  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

  Present, 25 of 25. The failure is concrete: the bridge "is experiencing mechanical issues and is stuck in the upright position", not a vague disruption.

  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 University Bridge" is the named crossing, with campus access and the 4 p.m. football game identified as the affected destinations.

  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

  Present, 25 of 25. Readers are told to "use alternate routes until further notice" and encouraged to take Link Light Rail for the Husky game.

  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.

• Timepresent25/25

  Final assessment

  Present, 25 of 25. Timing is dense: "Sent at 1:01:37 PM Fri", stuck "for nearly two hours", updates at "10:18 a.m. Saturday" and "10:55 a.m. Sunday".

  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.

• Impactabsent4/25

  Final assessment

  Absent, with only 4 of 25 reading it as present. The message describes rerouting and reopening to "cars, bikes and pedestrians" but states no injury, damage or danger from the stuck span.

  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.
