Very Severe Cyclonic Storm Yaas (Arabic pronunciation: [jaʔas][a]) was a relatively strong and very damaging tropical cyclone that made landfall in Odisha and brought significant impacts to West Bengal during late May 2021. The second cyclonic storm, second severe cyclonic storm, and second very severe cyclonic storm of the 2021 North Indian Ocean cyclone season, Yaas formed from a tropical disturbance that the Indian Meteorological Department first monitored on May 23. Conditions in the basin favored development as the system became a deep depression later that day, before intensifying into a cyclonic storm on the next day, receiving the name Yaas. The system further intensified as it turned to the northeast, becoming a severe cyclonic storm on May 24 despite moderate wind shear. Marginally favorable conditions further continued as Yaas accelerated northeastward, strengthening to a Category 1-equivalent tropical cyclone and to a very severe cyclonic storm on May 25. Yaas crossed the northern Odisha coast around 20 km south of Balasore at its peak intensity as a very severe cyclonic storm on May 26. Upon landfall, the JTWC and IMD issued their final advisories as Yaas further weakened inland while turning north-northwestwards.
In preparations for the storm, many electrical companies in West Bengal and Odisha prepared additional generators and transformers for possible electrical problems. Evacuations were also ordered, starting on May 24 on low-lying areas in East Midnapore and West Midnapore and Jhargram. Hooghly, Kolkata and North 24 Parganas and South 24 Parganas are now placed on high alert.[3] Railway operations and marine activities were halted due to Yaas, while rescue authorities and medical teams were deployed in for possible emergencies. In Bangladesh, over two million individuals were ordered to be evacuated in coastal areas of the country due to the storm's approach. Food supplies and emergency funds were also released for the evacuees. 20 people across India and Bangladesh died due to Yaas.[4] West Bengal was the hardest hit Indian state, with an estimated loss of ₹210 billion (US$2.89 billion).[5] Odisha also suffered a loss of ₹6.1 billion (US$83.9 million).[6]
