In an advisory to chief secretary Aditya Prasad Padhi and special relief commissioner Bishnupada Sethi, the NERC said that a depression formed over southeast Bay of Bengal was likely to move northwestwards towards Odisha coast over the next 72 hours.

“The depression intensified on Tuesday and turned into a cyclonic storm. It is very likely to move northwestward towards Odisha and adjoining north Andhra Pradesh coast during the next 72 hours,” the advisory said.

The state government should take appropriate precautionary measures under such circumstances, it added.

HR Biswas, the director of meteorological centre in Bhubaneswar, also confirmed in the morning that a “depression has been recorded at a distance of around 720 km from Gopalpur coast in Odisha”.

Under the influence of the low pressure, Odisha is likely to experience heavy rainfall on October 10 and October 11, he stated.

Special relief commissioner (SRC) BP Sethi said he was in touch with the Indian Meteorological Department headquarters in New Delhi. The state government would issue alert to districts well in advance, he said.

The IMD, in a special bulletin Monday afternoon, said Odisha could expect heavy to very-heavy rainfall at isolated places in the coastal areas for four days, beginning on October 9.

Squally winds reaching a speed of 45 to 55 km per hour, gusting to 65 km per hour, were also likely to prevail along and off north Andhra Pradesh, Odisha and West Bengal coasts from October 9 afternoon, it said.

Fishermen have been advised not to venture into central Bay of Bengal from October 8 to 10 and northern part of the sea from October 9 to 11, the IMD bulletin added.
