A single hurricane response makes up nearly 38 percent of a year's emergency alerts
AI-generated · every claim is source-linkedBeginning Thursday, September 7, 2017, the University of Florida issued the first of a multi-day cascade of UF Alerts as Hurricane Irma (at the time the strongest Atlantic hurricane ever recorded outside the Caribbean and Gulf) approached Florida. UF closed its Gainesville campus Sunday, September 10 through Wednesday, September 13. According to the UF Alert 2017 After-Action Report, Irma accounted for 17 of 38 incidents and 27 of 72 messages issued through the UF Alert system in 2017, nearly 38 percent of the entire year's alert volume.

UF Alert AAR 2017 Attachment 1 (Wayback) — UF Alert-Systemwide Monday, September 11th, 2017, 7:11PMHow 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.
Lake Nona RAC will cancel classes starting Thursday, 9/7 through the weekend and Monday, 9/11. (1 of 2)
Sourceabsent4/25
Final assessment
Most reads found 'Lake Nona RAC' names a facility or site rather than a clear issuing authority or agency; a minority treated the facility name as an adequate sender identification, but the majority view that no authority is truly named wins out.
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.

Hazardabsent0/25
Final assessment
Unanimous: no reason or specific threat is given for the class cancellation.
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.

Locationpresent24/25
Final assessment
Nearly unanimous: 'Lake Nona RAC' is read as naming the specific affected site, with only one dissenting read treating it merely as the sender rather than a location.
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
Unanimous: the message is purely a schedule notice 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 dates are given, 'starting Thursday, 9/7 through the weekend and Monday, 9/11.'
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
Unanimous: no consequence or severity 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.
