Whenever the Chief of Police or other authorized city official finds that falling snow, sleet or freezing rain will create a condition which makes it necessary that the parking of motor vehicles on snow emergency routes be prohibited, or whenever he or she finds on the basis of a firm forecast of snow, sleet or freezing rain that the weather conditions so forecasted may create a condition making it necessary that parking be prohibited, he or she is authorized to announce the prohibition, to become effective at a time specified by him or her. After the effective time of the prohibition, no person shall park any vehicle or permit any vehicle to remain parked on a snow emergency route. However, if a fall of snow, sleet or freezing rain occurs after 11:00 p.m. and prior to 6:00 a.m., and the Chief of Police or other authorized city official has not announced prior to 11:00 p.m. that parking on snow emergency routes is to be prohibited after a specified time, a vehicle parked on a snow emergency route may remain so parked until 7:00 a.m. following the fall. The prohibition of parking announced by the Chief of Police or other authorized city official under the authority of this section shall remain in effect until he or she announces the termination of the snow emergency, in part or in which the prohibition of parking authorized by this section shall no longer be in effect.
