Most of the deaths occurred in Beira -- a port hub and capital of Sofala province -- a city which has virtually been cut off after power lines crashed, the airport was shut and roads swamped by flooding.
The flooding had already killed 66 people nationwide in days preceding the cyclone.
"There has been a lot of damage. Many homes have been left without roofs," he added.
"Unfortunately there is extreme havoc," said the official.
"Some runway lights were damaged, the navigation system is damaged, the control tower antennas and the control tower itself are all damaged.
"The runway is full of obstacles and parked aircrafts are damaged." Late on Wednesday, the national carrier LAM cancelled all flights to Beira and Quelimane, which is also on the coast, as well as to Chomoio, which is inland.
Power utility Electricidade de Mocambique said in a statement that the provinces of Manica, Sofala and parts of Inhambane have been without power since Thursday.
Another official, Pedro Armando Alberto Virgula, in Chinde north of Beira, said a hospital, police station and seven schools there lost their roofs and several houses were destroyed.
Bonifacio Cebola, a spokesman for the Beira Central Hospital, said that the theatre at the country's second largest hospital was not spared and surgeries have been suspended. "Because of the cyclone, the (theatre) no longer has conditions for patients to be operated on," Cebola said to Radio Mo?ambique.
Local officials said that this week's heavy rains had already claimed 66 lives, injured 111 people and displaced 17,000 people.
The UN Office for the Coordination of Humanitarian Affairs (OCHA) had warned that the storm could pack winds of up to 190 kilometres per hour (118 miles per hour).
Heavy rains in neighbouring Malawi have affected almost a million people and claimed 56 lives, according to the latest government toll.
Authorities there have opened emergency relief camps where malaria and shortages of supplies have led to dire conditions, according to AFP correspondents.
