(4) no other person appears to have authority to act in the circumstances;
the court, on petition by any person or on its own motion, may appoint a temporary guardian for the incapacitated person or minor for a specified period not to exceed ninety (90) days. Upon notice and hearing, the court may, with good cause shown, grant one (1) extension of the temporary guardianship for not more than ninety (90) days. No such appointment shall be made except after notice and hearing unless it is alleged and found by the court that immediate and irreparable injury to the person or injury, loss, or damage to the property of the alleged incapacitated person or minor may result before the alleged incapacitated person or minor can be heard in response to the petition. If a temporary guardian is appointed without advance notice and the alleged incapacitated person or minor files a petition that the guardianship be terminated or the court order modified, the court shall hear and determine the petition at the earliest possible time.
