According to the official, 32 people died and 25 were missing, with another 2,653 people displaced by the disaster, the media said.
The Iranian interior ministry issued a special weather warning on Friday over the torrential rains that hit multiple regions across the country this week and have caused mudslides and widespread flooding. The cities of Isfahan and Shiraz have closed their metro systems in preparation for the inclement weather, Iranian media reported.
"The entire country is now on alert and all the necessary resources for all regions have been mobilized," Interior Minister Ahmad Vahidi was quoted as saying by the Tasnim news agency.
Iranian president Ebrahim Raisi urged the provincial governors to mobilize powers to help the population and rescue the victims.
Heavy rains and flooding that swept across Iran this week caused power outages in hundreds of Iranian villages and towns and left around 14,000 people homeless.
