On Tuesday, September 11, 2018, Duke University announced via DukeALERT that all classes would be cancelled after 5:00 PM EDT Wednesday, September 12 through Saturday, September 15, as Hurricane Florence (at the time a Category 4 storm with sustained 140-mph winds) approached the North Carolina coast. Duke's VP for Public Affairs Michael Schoenfeld explicitly stated Duke was 'not advising students to leave campus,' citing the fact that most Duke students come from outside North Carolina and around the world and would have nowhere safer to evacuate to. The university's severe weather and emergency conditions policy was activated at noon EDT Thursday, September 13. All scheduled athletic events on campus from Thursday through Sunday were cancelled or postponed.

Some messages in this sequence are documented (their existence, timing, and channel are sourced) but their exact wording is not preserved in the public record. Those entries appear as placeholders; only confirmed text is displayed.
This message is documented at this point in the sequence, but its exact wording is not preserved in the public record. The public edition displays only confirmed alert text.
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.
Due to Hurricane Florence, Duke classes will be canceled after 5 p.m. Wednesday. The severe weather policy will be effective at noon on Thursday. Additional updates will be posted on http://today.duke.edu. https://buff.ly/2MkPFL9
Final assessment
A clear majority read 'Duke classes will be canceled' as sufficiently naming Duke University as the issuing sender, while about a fifth of reads felt this implicit self-reference fell short of a truly named authority.
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: 'Hurricane Florence' 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: no specific location is given beyond the university itself, with no building or address named.
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: the message only announces class cancellation and policy timing, with no protective action instructed.
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
Unanimous: specific times are given, 'after 5 p.m. Wednesday' and 'noon on Thursday.'
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: no consequence or severity of the hurricane is stated.
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.
