(a) A person apprehended under this subchapter may be detained for not longer than 24 hours after the time that the person is presented to the facility unless an application for court-ordered treatment is filed and a written order for further detention is obtained under § 462.065.
(b) If the 24-hour period ends on a Saturday, Sunday, or legal holiday, the person may be detained until 4 p.m. on the next day that is not a Saturday, Sunday, or legal holiday. If extremely hazardous weather conditions exist or a disaster occurs, the presiding judge or magistrate may, by written order made each day, extend by an additional 24 hours the period during which the person may be detained. The written order must declare that an emergency exists because of the weather or the occurrence of a disaster.
