Thunderstorms and lightning near Notre Dame Stadium ahead of the October 18, 2025 rivalry game against USC kept fans from entering the stands and prompted the university to direct fans to shelter in nearby campus buildings. Several pregame festivities were canceled, but the university later said it was safe to resume normal activity and the game was played without an in-game delay.

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.

Final assessment
Unanimous agreement no sender or issuing authority is named, only the generic 'WEATHER ALERT' label.
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 agreement 'Lightning has been detected' names a 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 agreement the message names specific shelter buildings such as LaFortune Student Center and Hesburgh Library.
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 agreement the message instructs recipients to shelter in their car or one of the listed campus buildings.
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
A clear majority found no clock time or date given, with only a few reads crediting 'has been detected' as implying a current moment. The majority holds absent.
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 agreement no danger or consequence of the lightning is explicitly 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.
