Bhubaneswar/Kolkata: Cyclone ‘Amphan’ gathered strength and intensified Sunday into a severe cyclonic storm over the Bay of Bengal. It is certainly going to trigger heavy rainfall coupled with high-velocity wind in several coastal districts of Odisha and parts of West Bengal, officials said. Cyclone Amphan is likely to cross West Bengal-Bangladesh coasts between Sagar Islands in West Bengal and Hatiya islands in Bangladesh between afternoon and evening of May 20 as a very severe cyclonic storm, Regional MeT Director in Kolkata GK Das said.
Gathering strength
According to a bulletin issued by the weather office at 2 pm, AMPHAN (pronounced as UM-PUN) moved slowly northwestwards with a speed of three kmph and has intensified into a severe cyclonic storm. It lay centred about 980 km south of Paradip in Odisha, 1,130 km south-southwest of Digha in West Bengal and 1,250 km south-southwest of Khepupara in Bangladesh. It is likely to intensify further into a very severe cyclonic storm during the next 12 hours and then move nearly northwards slowly during the next 24 hours.
Movement of ‘Amphan’
Thereafter, it is likely to re-curve north-northeastwards and move fast across northwest Bay of Bengal and cross West Bengal-Bangladesh coasts between Sagar Islands and Hatiya islands between afternoon and evening of May 20, said HR Biswas, Director of the Meteorological Centre in Bhubaneswar.
Under its impact, the coastal districts of Gangetic West Bengal, including North and South 24 Parganas, Kolkata, East and West Midnapore, Howrah and Hooghly are likely to experience light to moderate rain at many places with heavy downpour at isolated places May 19, Das said.
Heavy rainfall expected in coastal Odisha
In Odisha, ‘Amphan’ is likely to trigger heavy rainfall in some parts of Gajapati, Ganjam, Puri, Jagatsinghpur and Kendrapara districts, while moderate rainfall will lash other coastal areas Monday onwards, the MeT Centre said.
