Severe Cyclonic Storm Yaas (Arabic pronunciation: [jaʔas][a]) is a currently strengthening tropical cyclone in the Bay of Bengal. The third depression, second deep depression, second cyclonic storm, and second 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, and the system received 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.

In preparations for the storm, many electrical companies prepared additional generators and transformers for possible electrical problems. Evacuations were also ordered, starting on May 24 on low-lying areas in East and Medinipur and Jhargram. Hooghly,Kolkata and North & South 24 Parganas are now placed on high alert.[2]

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).[3] Meanwhile, the JTWC issued a Tropical Cyclone Formation Alert at 15:00 UTC on May 22 on the consolidating system.[4] The system subsequently intensified into a deep depression at 15:00 UTC on May 23.[5] 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.[6] 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.[7][8] The IMD further upgraded Yaas to a severe cyclonic storm at 18:00 UTC that day as the system became more organized.[9] A subtropical ridge turned the system to the northeast, into an area of low wind shear, causing Yaas to gradually strengthen.[8]

The Union Power Ministry has prepared for transformer and generators for restoration of electricity. The Health Ministry is also preparing to ensure no disruption in vaccine supplement and COVID 19 treatment. The Ministry of Telecommunication has also kept all telecom towers and exchanges under watch..[10] Prime Minister Narendra Modi has also arranged an emergency meeting to prepare for the cyclone.[11]

The NDRF has deployed 65 teams with another 20 teams on reserve. 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.[12] CESC stayed on guard for the cyclone to ensure uninterrupted service especially for major hospitals and critical establishments like drainage pumping stations. [13]

Additionally, Northern Railway have canceled many trains from New Delhi to and from Bhubaneswar and Puri.[14] Meanwhile, Western Railways and Southern Railways have also canceled trains going to and from Odisha.[15][16]

The IMD issued an orange alert on May 25 on Mayurbhanj, Jajpur, Cuttack, Khordha, and Puri in Odisha, following the threat of Yaas' rainfall.[17]. Meanwhile, a red alert was raised by the department on Kendrapara, Jagatsinghpur, Bhadrak, and Balasore on the same day due to the system.[17] Ministry of Home Affairs Amit Shah instructed the authorities in West Bengal, Odisha, and Andhra Pradesh in a virtual meeting to prepare for the back-up of electricity supplies at hospitals and vaccine centers for possible power outages.[18] The Port of Kolkata started to suspend all shipping activities in the city, starting on May 25 due to Yaas' threat.[19][20] 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.[21]
