Tropical cyclone Idai battered Mozambican coastal city Beira Friday, leaving half a million people virtually cut off after power lines crashed, airport shut and roads were swamped by flooding that killed 66 people nationwide.
"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.
"There was no tsunami-type storm but Beira and Chinde (400 kilometres, 250 miles northeast of Beira on the coast) were badly hit," added the NIDM official.
Another official, Pedro Armando Alberto Virgula, in Chinde, said a hospital, police station and seven schools there lost their roofs and four houses were destroyed.
Virgula added that efforts were under way to assess the damage caused after Idai made landfall late on Thursday.
Local officials said that this week's heavy rains 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.
The UN warned of damage to crops, "including about 168,000 hectares (415,000 acres) of crops already impacted by flooding in early March, which will undermine food security and nutrition".
In neighbouring Zimbabwe, weather services have warned that violent thunderstorms, lightning and strong winds will be experienced in the eastern regions of the country.
