  "context": "The [University of Oklahoma](https://en.wikipedia.org/wiki/University_of_Oklahoma) sits in [Norman, Oklahoma](https://en.wikipedia.org/wiki/Norman,_Oklahoma), squarely in [Tornado Alley](https://en.wikipedia.org/wiki/Tornado_Alley). OU maintains a heavily drilled tornado response protocol and a [well-established RAVE alert system](https://ou.edu/news/articles/2024/september/ou-rave). The November 2024 tornado warnings came during a multi-day severe weather outbreak that had already caused major tornado damage across the Oklahoma City metro area. For OU, tornado warnings are not rare events; they are a routine part of campus life during storm season. What makes overnight warnings particularly challenging is that students in residence halls may be asleep with phones on silent, and the RAVE system must compete with ambient noise and sleep for attention. OU supplements SMS alerts with outdoor sirens and building-level PA announcements during tornado warnings.",
  "keyFindings": [
    "OU's tornado alert format embeds the timestamp directly in the message text, ensuring the time is visible even if the SMS metadata is stripped",
    "The 160-character initial alert fits exactly in a single SMS segment, a deliberate design choice for the most time-critical emergency type",
    "Three alerts in 40 minutes demonstrates the sustained communication cadence needed for evolving weather threats",
    "Overnight timing (1:22 a.m. CST on November 3, 2024) represents the worst-case scenario for student notification, asleep, phones potentially silenced"
