Very Severe Cyclonic Storm Yaas (Arabic pronunciation: [jaʔas][a]) was a tropical cyclone over Jharkhand that made a devastating landfall in 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.[4] 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. Warnings were issued by the Indian Meteorological Department and Bangladesh Meteorological Department as Yaas impacts these areas.

As of May 27, nine people have been reported dead due to Yaas. Of them, two died in a tornado which struck West Bengal's Hooghly District, according to Chief Minister Mamata Banerjee. Another died as a tree fell onto him, and a teen was found dead in a river. Two farmers had also died after being struck by lightning, and an elderly woman was trapped in a collapsed house, eventually dying there. Two more individuals were killed as they were crushed by uprooted trees.[5]

On May 22, a low pressure area formed in the Bay of Bengal. On the next day, at 09:30 UTC, the disturbance intensified into a depression, and was assigned the designation BOB 02 by the India Meteorological Department (IMD).[6] Meanwhile, the JTWC issued a Tropical Cyclone Formation Alert at 15:00 UTC on May 22 on the developing system.[7] The system subsequently intensified into a deep depression at 15:00 UTC on May 23.[8] On the following day, at 02:30 UTC, the system further intensified into a cyclonic storm, and was given the name Yaas by the IMD.[9] At that time, the low-level circulation center of the system became partially-exposed, due to moderate wind shear; however, large masses of rainbands persisted in the southern portion of the storm as it remained in a marginally favorable environment for intensification, with warm sea surface temperatures and good outflow but moderate wind shear.[10][11] The IMD further upgraded Yaas to a severe cyclonic storm at 18:00 UTC that day as the system became more organized.[12] A subtropical ridge turned the system northeast into an area of low wind shear, causing Yaas to gradually strengthen.[11] At 12:00 UTC on May 25, the JTWC upgraded the storm to a Category 1 system as the system further organized.[13] Despite Yaas being negatively affected after making landfall, combined with the weakening effects of moderate wind shear and poor outflow, it intensified further to a very severe cyclonic storm at 15:00 UTC on May 25 as it featured an profound convection.[14] The storm subsequently reached its peak intensity of 140 km/h (85 mph) in three-minute sustained wind speeds, according to the IMD; the JTWC had slightly lower estimates of 120 km/h (75 mph) on the system.[14][15] Around 09:00 IST (03:30 UTC) on May 26, Yaas made landfall north of Dhamra Port and south of Bahanaga at the same intensity.[16] Upon moving inland, the JTWC issued their final warning on the storm as it weakened to a tropical storm, since it was over land and also faced increased vertical shear.[17] Soon afterwards, the IMD also discontinued advisories as the system became disorganized.

Preparations

The Union Power Ministry of India had prepared transformers and generators in case of power outages. The Health Ministry also prepared to ensure that there is no disruption in vaccine supplement and COVID-19 treatment. The Ministry of Telecommunication kept all telecom towers and exchanges under watch.[18] India Prime Minister Narendra Modi had also arranged an emergency meeting to prepare for the cyclone.[19] The NDRF has deployed 65 teams with another 20 teams on reserve. Also, NDRF deployed 115 teams in 5 states.[20] Rescue and relief teams of the Indian army, navy, and the coast guard have also deployed over the coastal districts of Odisha and West Bengal.[21] CESC stayed on guard for the cyclone to ensure uninterrupted service especially for major hospitals and critical establishments like drainage pumping stations. [22] Additionally, the Northern Railway zone had cancelled many trips from New Delhi to and from Bhubaneswar and Puri.[23] Meanwhile, Western Railways and Southern Railways had also canceled trains going to and from Odisha.[24][25] Airline operations at Kolkata International Airport were cancelled due to the forecasted interminent weather from Yaas.[26]

The IMD issued an orange alert on May 25 on Mayurbhanj, Jajpur, Cuttack, Khordha, and Puri in Odisha, citing the threat of Yaas' rainfall.[27] Meanwhile, a red alert was raised by the department for Kendrapara, Jagatsinghpur, Bhadrak, and Balasore on the same day due to the system.[27] Ministry of Home Affairs Amit Shah instructed the authorities in West Bengal, Odisha, and Andhra Pradesh in a virtual meeting to prepare electricity supplies at hospitals and vaccine centers for possible power outages.[28] The Port of Kolkata started to suspend all shipping activities in the city, starting on May 25 due to Yaas' threat.[29][30] All 265 boats which were reported to be in the Bay of Bengal on that day returned to the port as the Indian Coast Guard instructed them to do so due to the brewing storm.[31] Evacuations were also started on May 24 for the coastal and low-lying areas in East Midnapore and West Midnapore and Jhargram, with over a million people being evacuated.[4][32] Meanwhile, as Yaas weakens over Jharkhand, evacuations were ordered due to the threat of strong winds and heavy rainfall from the system.[33] Over 600,000 individuals or 6 lakh were instructed to move to disaster shelters provided by the authorities due to the storm's approach.[33]

Bangladesh

Assessing the threat of Yaas in the country, Bangladesh Prime Minister Sheikh Hasina reserved 225 disaster centres for evacuation premises.[34] 349 shelters had been prepared, which accommodated half the capacity of people to maintain Covid-19 health restrictions.[35] 114 medical authorities were readied for medical emergencies.[35] Food supplies were also prepared for the evacuees, while Bangladeshi authorities including the Cyclone Preparedness Programme of the country and its navy were on standby and high alert, starting from May 24.[34][35] Signal Warning No. 2 were raised on harbors in Chittagong, Cox's Bazar, Mongla and Payra on the same day as Yaas neared the country.[34] In the administrative division of Barisal, authorities there started to prepare temporary and permanent evacuation shelters as they started to depopulate over 2 million individuals due to the storm.[36] Fishing activities in the northern Bay of Bengal were prohibited.[34] Tk15 million ($17,690 USD) worth of standby funds were also released by the authorities for disaster response. 20,000 Rohingya at the remote island of Bhasan Char were also considered at risk.[36][32]

Sri Lanka

The meteorology department of Sri Lanka issued a red alert on May 24 for the possibility of heavy rains and strong winds from Yaas for the country's Western, Central, Sabaragamuwa and Southern provinces.[37]

Impact

Rainfall totals forecast in India from Cyclone Yaas from May 25 to May 29

India

Yaas is the second storm to hit the country of India, weeks after Cyclone Tauktae bashes over Gujarat during early-to-mid May, killing over 7 individuals and leaving 81 more missing.[38] The former coincided with a perigean spring tide, causing high tides when the storm approached land.[39]

Starting on May 25, heavy rains and strong winds started to brush the coastal and inner areas of Odisha and West Bengal, and as far as Kolkata.[40] In the latter's Hooghly District, a tornado struck Bandel and killed two people, both due to electrocution from fallen power lines, while five were injured.[41][42][43] Knee-deep floods submerged the beach areas of Digha due to torrential rainfall, while palm trees were snapped by gusty winds.[44][45] Chandabali and Paradeep received over 17 cm (6.5 inches) of rainfall from May 25, also causing flooding.[44][46] 3 lakh houses were damaged in West Bengal, while around 1 crore people were affected in the state alone.[47] In North 24 Parganas, strong winds uprooted many trees and electrical poles were damaged.[26] A fatality was reported on May 26 in the town of Keonjhar, when a man died after a tree fell on top of him.[48] 10 individuals were rescued from a capsized boat off the Odisha coastline.[49] A 15-year old boy was found dead in a pond, located in the village of Jagannath Khunta in Mayurbhanj.[50] Two farmers from Pandua were struck by lightning while on their fields, killing them both, while a senior citizen from Asansol died as her house collapsed on top of her.[51] Two more individuals were killed as they were hit by uprooted trees in the West Bengal.[52] On the other hand, over 1,100 villages in West Bengal were submerged in floodwaters caused by storm surges, leaving an estimated 500,000 homeless.[53] Cars were also inundated by rising floods while infrastructures throughout the area suffered destruction.[53] 300,000 houses were also reported to be damaged in the state, affecting 10 million residents and inhabitants.[53]

In the state of Odisha, over 120 village settlements were also drenched by heavy rains, including seawater; however, no one was affected as all the residents in the area were safely evacuated to disaster shelters.[53] Farmlands throughout the state, western Bengal, and some in Jharkhand were also damaged by flooding, while small boats on the shores of the Bay of Bengal were wrecked.[54] Electrical lines in these states were affected, causing power outages.[54]

Bangladesh

Tidal waves generated by Yaas flooded low-lying areas in Khulna, Satkhira, Patuakhali, Barguna, Jhalokathi, and Noakhali, including some fishing settlements in Sundarbans on May 26.[55] The coastal areas of Cox's Bazar saw inundation in multiple villages due to Cyclone Yaas, while tidal surges severely damaged a jetty and at least 50 houses at St. Martin's Island.[56] According to naval sources at Patenga in Chittagong, a ship, called MV Sanvalli, sank near Bhasanchar in the Bay of Bengal and 12 sailors were rescued by Bangladesh Air Force helicopters.[57]
