  "context": "Washington University in St. Louis sits on the Danforth Campus straddling the city's western edge. On the afternoon of Friday, May 16, 2025, a violent tornado tore a roughly [23-mile path across the St. Louis region](https://www.weather.gov/lsx/05_16_2025), killing five people and damaging or destroying an estimated 5,000 structures, with North St. Louis hit hardest. The storm [struck the Danforth Campus around 2:45 p.m.](https://source.washu.edu/2025/05/danforth-campus-suffers-moderate-damage-in-st-louis-storm/), damaging building roofs and concrete, knocking down large trees that blocked roads, and causing widespread power and technology outages. People on campus were directed to shelter; one physical therapy student described being [moved into the basement of the Sumers Recreation Center](https://www.studlife.com/news/2025/05/16/washu-campus-and-surrounding-areas-sustain-tornado-damage) when the warning sounded. No injuries were reported on campus. WashU had tested its full multi-channel alert system in March 2025, and after the storm the [university community mobilized recovery and volunteer efforts](https://source.washu.edu/2025/05/washu-community-answers-call-to-help-in-north-st-louis/) across the broader region.",
  "keyFindings": [
    "Despite moderate campus damage from a tornado that killed five people regionally, WashU reported no injuries on campus, an outcome attributed to active sheltering in lowest-level interior spaces",
    "WashU had conducted a full multi-channel WashU Alert test (calls, email, text, beacons, fire-alarm voice, desktop pop-ups and app alerts) in March 2025, roughly two months before the real tornado warning",
    "The lingering campus hazards were downed trees, blocked roads and power/technology outages rather than structural collapse, which is why post-storm messaging stayed in update mode rather than declaring an all-clear"
