Severe storms with more than 900 lightning strikes and 1.25 inches of rain forced the evacuation of Ross-Ade Stadium ahead of Purdue's game against USC, with teams pulled from the field at 3:11 p.m. ET and fans sent to nearby buildings. Fans were directed to Mackey Arena, Holloway Gymnasium and Lambert Fieldhouse during a delay that lasted more than three hours.

Confirmed wording is transcribed character-for-character from a primary source. Use Verify this quote under each message to open that source in a new tab and compare the text yourself.
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 inclement weather in the area today's game won't start at the original 3:40 PM ET kickoff. Stay tuned for updates.
Final assessment
All reads agree no sender, agency, or system name appears anywhere in the text.
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
Reads split roughly evenly on whether generic 'inclement weather' counts as naming a hazard. Majority sided with present since a weather cause is explicitly cited, even though it lacks specificity like rain/lightning/tornado.
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 venue, stadium, or location is named anywhere in the message.
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
Reads are split on whether 'stay tuned for updates' counts as guidance since it's not a protective action, but a narrow majority counted it as minimal monitoring instruction.
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
Nearly unanimous: the message gives the specific original kickoff time of 3:40 PM ET and references 'today'.
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, danger, or severity is stated beyond the scheduling delay itself.
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.
