A deep depression over the Bay of Bengal is all set to intensify into a cyclonic storm by Saturday and it is likely to bring heavy rainfall in several parts of Odisha, the weatherman said Friday.
Though there is no cyclonic storm threat to Odisha, isolated heavy rainfall is likely in Malkangiri, Koraput, Rayagada, Nabarangpur, Kalahandi and Kandhamal districts on December 17, said H R Biswas, the Director of the Meteorological Centre here.
Light to moderate rain is likely to occur at several places over the state from December 16 to 18, the meteorological centre here said in a bulletin.
The Met Centre said the depression over south-east Bay of Bengal formed on Thursday intensified into a deep depression on Friday. It moved in the north-north-west direction and lay centred about 1,090 km southeast of Machilipatnam in Andhra Pradesh.
It is likely to intensify into a cyclonic storm in the next 24 hours and into a severe cyclonic storm in the next 36 hours. It will move in north-north-west direction and cross Andhra Pradesh coast between Ongole and Kakinada on December 17 afternoon, it said.
Fishermen have been advised not to venture into southwest and adjoining west-central Bay of Bengal on Saturday and west-central and adjoining southwest Bay of Bengal on December 16 and 17, Biswas said.
