Cyclone Yaas (pronounced as Yass) over eastcentral Bay of Bengal intensified to a severe cyclonic storm on Monday night, according to India Meteorological Department

At 11.30pm on Monday, Yaas lay centred at about 390 km southsoutheast of Paradip (Odisha), 490 km south-southeast of Balasore (Odisha), 470 km southsoutheast of Digha (West Bengal), and 500 kms south-southwest of Khepupara (Bangladesh).

It is very likely to move north-northwestwards, intensifying further into a very severe cyclonic storm during the next few hours. It would continue to move north-northwestwards, intensify further and reach northwest Bay of Bengal near north Odisha and West Bengal coasts by Wednesday early morning. It is very likely to cross north Odisha-West Bengal coasts between Paradip and Sagar Island around Balasore, during Wednesday noon as a very severe cyclonic storm.

Initially, IMD had said Yass would make landfall around Wednesday evening but advanced the time of landfall on Monday. “At the time of landfall, we are expecting wind speed to be around 155 to 165 kmph gusting to 185 kmph. Once Yaas intensifies to a Severe Cyclone we are also expecting its sea travel to be faster which is why the landfall time has been advanced,” said Sunitha Devi, in charge, cyclones at IMD.

Though oceanic and atmospheric conditions over Bay of Bengal are extremely favourable for intensification of Yaas, experts hope it will not intensify to an extremely severe cyclone because Yaas has formed relatively close to the coast and has less time over the unusually warm ocean.

Extensive damage is expected along north Odisha and WB coasts on May 26. There could be total destruction of thatched houses and extensive damage to kutcha houses; some damage to pucca houses; potential threat from flying objects; bending or uprooting of power and communication poles; flooding of escape routes; disruption of railways, overhead power lines and signalling systems; widespread damage to standing crops, plantations, orchards, falling of coconuts and tearing of palm fronds; blowing down of bushy trees; small boats, country crafts may get detached from moorings.
