Thousands of people were homeless Thursday after a cyclone battered Covid-ravaged India and neighbouring Bangladesh, killing nine people including four children.
Cyclones are a regular menace in the northern Indian Ocean but many scientists say they are becoming more frequent and severe as climate change warms sea temperatures.
Barely a week after Cyclone Tauktae claimed at least 155 lives in western India, Cyclone Yaas forced the evacuation of more than 1.5 million people in the eastern states of West Bengal and Odisha.
The storm hit on Wednesday with torrential rain and howling winds gusting up to 155 kilometres (96 miles) an hour, equivalent to a category two hurricane.
Waves the size of double-decker buses pounded the shore and swamped towns and villages along the coastline, exacerbated by a higher-than-normal tide because of a full moon.
Prabir Maity, a resident of a village close to the sea, told AFP: "I have lost my home, everything."
Two people died in West Bengal, two in Odisha and five in neighbouring Bangladesh, officials said.
In southern areas of Bangladesh, although not in Yaas's direct path, the sea smashed through water defences and inundated thousands of homes, officials said.
West Bengal chief minister Mamata Banerjee said more than 300,000 homes were destroyed.
"The water level in the sea and rivers started to swell to over three to four metres (nine to 12 feet) above the normal level and breached embankments in 135 places," Banerjee said.
"Thousands of people are still marooned. We have set up 14,000 cyclone centres to provide shelter to the homeless," she said.
Low-lying areas of state capital Kolkata were also flooded after the Hooghly river rose.
West Bengal disaster management minister Javed Ahmed Khan told AFP that rescue efforts were being "complicated" by villagers refusing to leave their homes because of fears about coronavirus.
"Water is everywhere. The situation is very grim," Arjun Manna, a resident of Kakdwip in the Sunderbans delta and nature reserve area, told AFP by phone.
"The devastation is huge. Most hotels and markets are still inundated. The sea is still roaring," Diprodas Chatterjee from the Hoteliers' Association in the seaside town of Digha told AFP.
"Employees who stayed back are telling a grim story," he said.
Milan Mondal, a senior forest official, told AFP that the high waves had also swamped a crocodile breeding centre and tiger reserve project area in the Sunderbans.
"At least five deer and a wild boar were rescued by forest officials," he said. "We are afraid that many crocodiles have left the breeding centre."
In Odisha hundreds of trees were uprooted, some bringing down power lines, relief official Pradeep Kumar Jena said.
Some thatched homes were also damaged during the storm, but telecommunication networks were not affected, he added.
Yaas has since moved inland towards the state of Jharkhand, easing to a deep depression but bringing heavy rains.
