Heavy rain is likely to lash several parts of Odisha over the next two days owing to the formation of a low-pressure area in the region, the Met office here said today. Under the influence of a cyclonic circulation, a low-pressure area has formed over coastal areas of West Bengal, north Odisha and adjoining the northwest Bay of Bengal, the Meteorological Centre here said. The system is likely to become more marked during the next 24 hours, it said. Under its impact, moderate rain and thundershower are likely to occur at most places, while heavy to very heavy rainfall is forecast at some places in Dhenkanal, Angul, Deogarh, Sambalpur, Bolangir, Jhaesuguda, Baragarh and Keonjhar districts, it said. Some areas in Puri, Ganjam, Khurda, Cuttack, Balasore, Mayurbhanj, Kalahandi, Boudh, Sonepur and Sundergarh districts are likely to get heavy rainfall as well, it said. In view of the likely adverse weather conditions, the Met office has advised fishermen who have ventured out to deep sea to return to the coast. Fishermen have also been advised not to venture into the sea along and off Odisha coast and northwest Bay of Bengal tomorrow and the day after. Most parts of Odisha have been lashed by heavy rains since the beginning of this month due to several spells of low pressure.
