ND Alert (the university's RAVE-powered emergency notification system) distributed emails to all Notre Dame email addresses between 12:46 and 12:48 a.m. EDT and SMS messages to registered phones at 12:53-12:54 a.m. EDT. The reported text instructed recipients to 'Go inside, to lowest level. Take cover immediately.' Residents of residence halls evacuated to the lowest floors of their buildings while the warning was active. The [NWS warning expired](https://police.nd.edu/emergency-preparedness/ndalert/) without any tornado touchdown reported at Notre Dame or in adjacent South Bend. Spring tornado warnings are not unusual in northern Indiana ([severe thunderstorms with high winds, hail, lightning, and tornadoes are most common in the spring](https://police.nd.edu/emergency-preparedness/emergency-situations/severe-weather/)) but the 1 a.m. timing made this alert notable. Earlier ND Alert tornado activations have included the [2018 St. Joseph County warning](https://www.facebook.com/notredame/posts/a-tornado-warning-has-been-issued-for-st-joseph-county-indiana-where-notre-dame-/10152952967558098/) and several spring activations that exercised the same SMS-and-email cadence.",
  "keyFindings": [
    "Email-first delivery (12:46-12:48 a.m. EDT) preceded SMS by 5-8 minutes",
    "The verbatim text differed slightly between email and SMS, the email used the older 'Go inside, to lowest level' shorthand while SMS used the longer 'lowest level of the building you are in' phrasing",
    "The activation came just before 1 a.m. EDT, when most students were in residence halls"
