Condition 1 remained in effect until 11:59 p.m. EDT as additional rounds of severe weather, including two consecutive Severe Thunderstorm Warnings with [60 mph wind gusts](https://alertcarolina.unc.edu/notifications/2026/03/16/17736988250001393697317/), moved through the area in the evening. UNC's Alert Carolina system maintains a publicly archived history of its notifications at alertcarolina.unc.edu/notifications/. The three-alert sequence on March 16, 2026 -- tornado watch, Condition 1 declaration, and two severe thunderstorm warnings -- demonstrates how a multi-phase severe weather event generates multiple distinct alert messages.",
