Overview
- Anhydrous ammonia leaked from a tanker trailer around 10 p.m. Wednesday in the Holiday Inn Express parking lot near East Main Street and Cypress Drive, according to Weatherford Fire.
- Roughly 500 people evacuated to the Pioneer Event Center at Southwestern Oklahoma State University after targeted alerts ordered evacuations and shelter-in-place within specified street boundaries.
- Thirty-six people were hospitalized, with 11 transferred to Oklahoma City–area hospitals for further treatment, and some were reported in critical condition.
- Authorities have lifted earlier shelter-in-place instructions, though the area around the hotel remains blocked off and air-quality checks continue.
- Local schools canceled classes and SWOSU closed its Weatherford campus, as officials advised residents to keep HVAC systems off earlier and noted I-40 exits were temporarily affected during the response.
