WEATHERFORD, Okla. – Beginning last night, hundreds were evacuated in an Oklahoma city after an ammonia gas leak in a hotel parking lot.

As of 10:30am on Thursday, the Weatherford Police Department said the air quality has reached safe levels, and they are releasing the shelter in place order. "Residents can return home at this time. Residents are encouraged to air out their residences by opening doors and windows."
