Answer:
Super Cyclonic Storm Amphan was a powerful and deadly tropical cyclone that caused widespread damage in Eastern India and Bangladesh in May 2020. It was the strongest tropical cyclone to strike the Ganges Delta since Sidr of the 2007 season and the first super cyclonic storm to occur in the Bay of Bengal since the 1999 Odisha cyclone.[1][2] Causing over US$13 billion of damage, Amphan is also the costliest cyclone ever recorded in the North Indian Ocean, surpassing the record held by Cyclone Nargis of 2008.
The first tropical cyclone of the 2020 North Indian Ocean cyclone season, Amphan originated from a low-pressure area persisting a couple hundred miles (300 km) east of Colombo, Sri Lanka, on 13 May 2020. Tracking northeastward, the disturbance organized over exceptionally warm sea surface temperatures; the Joint Typhoon Warning Center (JTWC) upgraded the system to a tropical depression on 15 May while the Indian Meteorological Department (IMD) followed suit the following day. On 17 May, Amphan underwent rapid intensification and became an extremely severe cyclonic storm within 12 hours.
On 18 May, at approximately 12:00 UTC, Amphan reached its peak intensity with 3-minute sustained wind speeds of 240 km/h (150 mph), 1-minute sustained wind speeds of 260 km/h (160 mph), and a minimum central barometric pressure of 925 mbar (27.32 inHg). The storm began an eyewall replacement cycle shortly after it reached its peak intensity, but the continued effects of dry air and wind shear disrupted this process and caused Amphan to gradually weaken as it paralleled the eastern coastline of India. On 20 May, between 10:00 and 11:00 UTC, the cyclone made landfall in West Bengal. At the time, the JTWC estimated Amphan's 1-minute sustained winds to be 155 km/h (100 mph). Amphan rapidly weakened once inland and dissipated shortly thereafter.
Coastal areas in Odisha—as well as Kolkata, Hooghly, Howrah, East Midnapur, North 24 Parganas, and South 24 Parganas in West Bengal—were affected by the cyclone. It also caused significant destruction in Bangladesh.

Answer:
Amphan made landfall on Wednesday, lashing coastal areas with ferocious wind and rain. The storm is weakening as it moves north into Bhutan.
Thousands of trees were uprooted in the gales, electricity and telephone lines brought down and houses flattened.
Many of Kolkata's roads are flooded and its 14 million people without power. The storm is the first super cyclone to form in the Bay of Bengal since 1999. Though its winds had weakened by the time it struck, it was still classified as a very severe cyclone.
Coronavirus restrictions have been hindering emergency and relief efforts. Covid-19 and social-distancing measures made mass evacuations more difficult, with shelters unable to be used to full capacity.Amphan began hitting the Sundarbans, a mangrove area around the India-Bangladesh border home to four million people on Wednesday afternoon, before carving north and north-eastwards towards Kolkata, a historic city that was the capital of the British Raj and widely known as Calcutta.
Parts of West Bengal and Orissa (also known as Odisha) states in India, and areas in south-west Bangladesh, bore the brunt, with winds gusting up to 185km/h (115mph).
At least 72 people have died in India's West Bengal state, and 12 deaths have been confirmed in Bangladesh.
West Bengal chief minister Mamata Banerjee said the devastation in Kolkata, the state capital, was "a bigger disaster than Covid-19".
"Area after area has been ruined," Ms Banerjee was quoted as saying by the Press Trust of India news agency. "I have experienced a war-like situation today."
