Effects of Cyclone Amphan in India
The effects of Cyclone Amphan in India were extensive and historic. Cyclone Amphan was the costliest tropical cyclone ever recorded in the North Indian Ocean, and the strongest cyclone ever since the 1999 Odisha Cyclone. It was the first storm, and strongest of the historic 2020 North Indian Ocean cyclone season, the costliest recorded cyclone season. It made landfall in West Bengal with 100 mph winds. Within India, the storm killed 98 people, and caused $13.8 billion (2020 USD). Amphan produced extremely high winds that ripped roofs off houses and uprooted trees, and  storm surges of in areas like Digha, West Bengal. Background. During 13 May 2020, an area of low pressure developed over the Southeastern Bay of Bengal about to the southeast of Visakhapatnam in the Indian state of Andhra Pradesh.<ref name="STWA 13/05/20"></ref> Over the next couple of days, the system became more marked as it gradually consolidated further, with bands of deep atmospheric convection wrapping into the system's low-level center.<ref name="TCFA 15/05/20"></ref> During 16 May, the India Meteorological Department (IMD) reported that the area of low pressure had developed into a depression and designated it as BOB  01 while it was located about to the south of Paradip in the Indian state of Odisha. Moving northwards, the depression continually organized and became a cyclonic storm a few hours later, receiving the name "Amphan". Due to conductive environments., Amphan underwent rapid intensification into a severe cyclonic storm, with the JTWC assessing an increase in winds from 140 km/h (85 mph) at 12:00 UTC to 215 km/h (130 mph), the equivalent to a Category 4 hurricane on the Saffir–Simpson scale (SSHWS), just six hours later. Furthermore, the IMD upgraded Amphan to an extremely severe cyclonic storm  on their cyclone intensity scale. The broad storm was characterized by a cloud shield extending more than 1,110 km (690 mi) and a sharply-outlined 10 nautical mile-wide eye. On May 18, the IMD classified Amphan as a Super Cyclonic Storm, with 3-minute sustained winds of 240 kph, reaching its peak intensity later that day. Early on May 20, Amphan went through an eyewall replacement cycle. Amphan was on a weakening trend. Around 5:30 p.m. IST (12:00 UTC), Amphan made landfall as a Very Severe Cyclonic storm near Bakkhali, West Bengal with winds of 155 km/h (100  mph). As it moved further inland, Amphan rapidly weakened. Just six hours after landfall, the JTWC downgraded the storm to a Category 1-equivalent cyclone and issued its final warning on the system, as it became disorganized. On 21 May, Amphan dissipated into a well-marked low pressure area. Preparations. Odisha. The government of Odisha directed the magistrates of four districts on 15 May to establish shelter homes for possible evacuees. Odisha Chief Secretary Asit Kumar Tripathy initially identified 403 possible cyclone shelters in areas potentially impacted by Amphan, though 105 served as temporary medical centres for quarantines associated with  the concurrent COVID-19 pandemic. Shelters could only be filled to one-third capacity to maintain social distancing guidelines due to the pandemic. West Bengal. Social distancing restrictions in West Bengal reduced evacuation capacity in shelters from 500,000 people to 200,000 people. The Kolkata Municipal Corporation located schools and community centres for possible use as temporary shelters to augment evacuation capacity. At least 1,704 shelters were ultimately established in Odisha and more than 2,000 were used in West Bengal, including schools and public buildings. The government of West Bengal planned to evacuate 200,000 people from their homes by 18 May; nearly  300,000 people evacuated in total from the state, including 200,000 from North 24 Parganas district and more than 40,000 from Sagar Island. Impact. West Bengal. The coastal districts recorded an estimated gusts of . In Kolkata, reports of car being overturned, trees uprooted and downed power lines caused into havoc. Some parts of the city remained without power. The streets were waterlogged and trees blocking the roads. Some districts got power in the middle of the night after the storm had passed. The airport was remained shut and became waterlogged, many structural damages were reported. Chief Minister Mamata Banerjee even stated  that "a bigger disaster than Covid-19". Netaji Subhash Chandra Bose Airport, Kolkata, recorded highest wind speed of 133 km/h on 20 May 2020. Other parts of Kolkata experienced wind speed of 110–130 km/h. Odisha. Although the state have escaped the worst part of the cyclone, it caused significant impact in the Odisha–West Bengal border districts. It affected 4.5 million people in the state. Due to high gust winds and intense rainfall, districts like Bhadrak and Kendrapara suffered especially for the paddy farmers since the paddy fields became unsuitable for paddy cultivation which was inundated by saline water  due to storm surge. According to the Odisha Government, 3 million people remained without power due to power outage and it took a while to return to normalcy whereas the roads were being cleared by the National Disaster Response Force (NDRF). In Mahakalapada and Rajanagar, around of lands were destroyed also because of saline water ingression and hundreds of acres of rabi crops were destroyed in Balasore and Bhadrak district. In the Dharma Port, an estimated wind speed of were recorded while Paradip recorded only . South India. Rains and strong winds from Amphan swept across many districts in Kerala beginning  on May 16. Thunderstorms associated with Amphan caused severe coastal erosion in the Valiyathura suburb of Thiruvananthapuram, damaging roads and destroying homes and threatening to displace over a hundred families from their homes. Strong winds inflicted severe damage in Kottayam district, especially in Vaikom taluk, where homes and temples were impacted and trees and electric poles were downed. A ₹1.47 billion (US$19.3 million) damage toll resulted from the destruction of 16 homes and the partial damage of 313 homes. A high school used as a homeless shelter collapsed, causing minor injuries. Tamil Nadu faced some impact from the  cyclone. Heavy winds damaged at least 100 boats anchored in the Ramanathapuram district. Coastal erosion from rough seas generated by Amphan led to the collapse of three houses at Bommayarpalayam in Viluppuram district. Roughly 35 acres of banana crops around Gandarvakottai and Aranthangi were destroyed. Northern areas of the state have heatwave-like conditions for a week because Amphan took all of the area's moisture. In Sooradapeta, near Kakinada in Andhra Pradesh, rough seas destroyed 35 homes and damaged several others. Aftermath. International Relief. German NGO Welthungerlife released 100,000 Euro to fund Cyclone Amphan relief efforts. West Bengal. On  22 May, Prime Minister Narendra Modi conducted an aerial survey over Kolkata, along with Chief Minister Mamata Banerjee. Modi announced a ₹10 billion (US$132 million) immediate relief package for West Bengal and ₹5 billion (US$66.2 million) in relief for Odisha. In advance, Modi announced that ₹200,000 (US$2,650) would be provided to the next of kin of people who died during the storm, and ₹50,000 (US$660) would be given to each injured person. West Bengal CM Banerjee stated that it would take three to four days to assess the damage. Twenty disaster relief  teams were dispatched by the Indian Coast Guard to begin search and rescue operations. Ten teams were sent to West Bengal to aid recovery, in addition to the NDRF teams pre-positioned there before Amphan's passage. Also since most of the water pumps are operated in electricity and due to no electricity, several district suffered from water shortage which caused additional protest. Approximately 1,000 ground teams worked to restore infrastructure and services in West Bengal after Amphan, though only 25–30 percent of workers were staffed due to the COVID-19 pandemic. The resulting slow restoration of power sparked protests across  West Bengal aimed primarily at electricity company CESC. Some restoration efforts were disrupted by these protests. The Home Department of West Bengal requested additional crews from railway and port interest, while five brigades from the Indian Army were deployed in Kolkata and the 24 Parganas districts to support recovery efforts. The government of Odisha sent 500 members of its disaster rapid action force and fire service to West Bengal. The European Union stated that it would initially provide €500,000 (US$545,000) for those affected by the storm in India. Odisha. Additional assistance was requested from Jharkhand and Odisha. Odisha  Chief Minister Naveen Patnaik performed an aerial survey of the damage in his state following Amphan.
