UPDATE Thursday morning, March 23: Traffic on Northlake Way is reopened between 6th and 7th Avenues NE and there are no further traffic impacts. ORIGINAL POST: A fire that destroyed about 30 boats this morning near the Ship Canal Bridge is affecting several nearby UW buildings on Northlake Way due to smoke and street closures.   The fire, which started at around 2 a.m., is under control, according to the Seattle Fire Department. Northlake Way is blocked in both directions between 6th Avenue and 7th Avenue, affecting access to the Publications Services Building, the Northlake Building, Mercer Court Apartments and the Department of Environmental & Occupational Health Sciences. Please use alternate routes. The smoke is minorly affecting air quality in the west part of the Seattle campus. Air quality in the central and north part of campus is satisfactory. If you are concerned about smoke exposure, keep windows and doors closed as much as possible. UW will continue to monitor the situation and provide updates here as they become available.

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.

    Final assessment

    Absent: Source in UW residual.

    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: Hazard in UW residual.

    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: Location in UW residual.

    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.

  • Guidanceabsent0/25

    Final assessment

    Absent: Guidance in UW residual.

    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: Time in UW residual.

    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.

  • Impactabsent0/25

    Final assessment

    Absent: Impact in UW residual.

    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.
