Bhubaneswar: Rainfall is likely to occur in many parts of Odisha in the next 48 hours under the influence of a low-pressure over central parts of the Andaman Sea.
According to Dr Sarat Chandra Sahu, director, Centre for Environment and Climate (CEC) at the SOA (Deemed to be University) and former director of Meteorological Centre, Bhubaneswar, a low pressure area formed over the South China Sea on Friday has moved further into the South Pacific ocean and lying over the central parts of the Andaman Sea (south-west Bay of Bengal) and its neighbourhood with an associated cyclonic circulation extending up to the mid-tropospheric level.
Though it is likely to intensify gradually and initially move in the west-north-west direction, the intensification and track movement of the low-pressure is complicated due to the mismatch in the consistency of different model products, he further said.
“Though some models indicated that it would intensify into a cyclonic storm which might cross the Tamil Nadu coast around November 15, other models indicate that the low-pressure would intensify into a deep depression in the west central Bay of Bengal around November 13 and weaken thereafter. However, there is a probability of cloud cover accompanied by light rainfall at many places and moderate rainfall at a few places over the coastal Odisha between November 12 and 15,” he pointed out.
The thick haze with cloud cover may continue over Odisha due to flow of pollutants from northwest India by the north-westerly and north-north-westerly wind flow towards the eastern state, he added.
Meanwhile, the India Meteorological Department (IMD) in an afternoon release on Saturday said that that there is no heavy rainfall warning for Odisha.
“The low-pressure which has concentrated into a depression over the south-east Bay of Bengal about 20 km north-west of Port Blair, 1340 km east-south-east of Chennai and 1390 km east-south-east of Nellore in Andhra Pradesh at about 8.30 am today, is most likely to concentrate into a deep depression in the next 24 hours and then a cyclonic storm in the subsequent 24 hours and move in the north-west direction during next 48 hours and later in the west-south-west direction towards the north Tamil Nadu and south Andhra Pradesh during the subsequent 72 hours,” the release said.
Though the IMD has said that there is no cyclone warning for the coastal belts of Odisha, it has advised the fishermen not to venture into the south-east and adjoining east-central Bay of Bengal on November 10, central and adjoining south-east Bay of Bengal between November 11 and 13 and the south-west and the adjoining west-central Bay of Bengal from November 13 as the conditions during the period is likely to be rough to very rough.
Meanwhile, distant cautionary signal no-1 has been hoisted at all ports in the state.
