A powerful cyclone destroyed tens of thousands of mud houses in eastern India on Wednesday, forcing the closure of the busiest regional airport in Kolkata, as it brought storm surges to coastal areas, the second such event within a week.

Cyclone Yaas was packing gusts of up to 140 kph (87 mph) as it hit land, authorities said, days after Tauktae tore up the western coast, triggering mass evacuations and piling pressure on authorities battling a deadly second wave of the coronavirus.

Authorities said more than a million people had been moved out of the storm's path, while television broadcast images of rough seas, strong winds and rains lashing the state of Odisha, with shops and homes boarded up.

By noon, the "very severe cyclone" would cross Odisha and its neighbour, West Bengal, weather officials said.

West Bengal's chief minister, Mamata Banerjee, told reporters that about 20,000 mud houses and temporary shelters had been damaged in the state.

"I have not seen anything like this before," said another state minister, Bankim Hazra, after seawater gushed into the low-lying areas of Sagar island in the Bay of Bengal and the tourist town of Digha, where a police station was flooded.

"Successive high tides battered the coastline," he added. "It is inundation all around and villages are cut off."

The state's Kolkata airport was closed to flights until Wednesday evening.

Cyclones in the Bay of Bengal are common at this time of year, and often roar ashore, bringing death and destruction to the coastal areas of both India and neighbouring Bangladesh.

Police said they had rescued 10 people after their boat capsized near shore in Odisha's Jagatsinghpur district on Tuesday. Naval base Chilka is monitoring ships in the area and is ready for rescue operations, the Indian Navy said.

The devastating wave of virus infections complicated storm preparations. Odisha officials said they had suspended testing, vaccination and a door-to-door health survey in the three districts in the storm's path.

With Cyclone Yaas predicted to make landfall on the eastern coast on May 26, the Indian Navy on Wednesday said it has stepped up and made all necessary arrangements for the rescue and relief operations.

"INS Chilka at Khurda has stepped up and made all necessary arrangements, to coordinate the rescue and relief operations in close liaison with State Government agencies with the support of Headquarters Eastern Naval Command Visakhapatnam," informed an official release by Indian Navy

The Indian Navy further said that it has been closely monitoring the very severe Cyclonic Storm Yaas closing in on the Eastern Coast which is likely to cross the between Badrak and Balasore districts on 26 May.

As part of the preparation, a 24*7 cyclone monitoring team has been established and is functional from 24 May, assorted relief material and community kitchen for thousands of people are being made ready for immediate deployment in consultation with state authorities.

The Naval Officer-in-Charge (Odisha) Operations Room has been monitoring ships movement along the coast in coordination with authorities at Gopalpur, Paradip and Damara ports.

"For maintaining constant communication with the Naval and civil authorities, constant liaison is underway from INS Chilka," it added.

Chief Minister Naveen Patnaik has urged the people living in the coastal regions of Odisha to cooperate with the local administration and shift to cyclone shelters. Addressing the people of the state yesterday, the CM also asked them to adhere to Covid-19 protocols and wear two masks.
