Cyclone 'Bulbul', currently moving at a speed of 13 kmph, may intensify further by Saturday, Biswas said.
It is unlikely to make a landfall in Odisha, but the state should brace for heavy to very heavy rainfall in its coastal and northern districts in the next two days, he said.
"The cyclone is very likely to intensify into severe cyclonic storm, re-curve north-eastwards and cross West Bengal-Bangladesh coasts across Sunderban delta on Sunday.
"The storm is expected to have a maximum sustained wind speed of 110 to 120 kmph, gusting up to 135 kmph, while crossing the coast," the senior IMD official explained.
According to IMD predictions, coastal Odisha is likely to experience wind speed of 70-80 kmph gusting up to 90 kmph, accompanied by heavy to very heavy downpour.
Several parts of Jagatsinghpur, Puri and Kendrapara witnessed heavy showers on Friday morning, with Odisha Special Relief Commissioner PK Jena asking the district collectors, mainly in the coastal and the northern region, to keep adequate arrangements in place to deal with possible waterlogging and flood-like situation.
Port authorities in Paradip have also taken steps to combat the storm, Jena said.
Officials have been told to ensure total suspension of fishing operations from Friday. Farmers have also been advised to take steps to protect crops and harvested paddy.
All schools and Anganwadi centres remained closed for the day in Puri, Jagatsinghpur, Kendrapara and Jajpur districts in view of the rough weather.
Jena said the schools would continue to remain shut on Saturday in nine vulnerable districts, including Puri, Khurda, Bhadrak, Balasore and Mayurbhanj.
Two teams of Odisha Disaster Rapid Action force (ODRAF) and one of the National Disaster Response Force are on standby in each of these districts, while adequate fire services personnel have also been deployed in these areas for necessary operations, the special relief commissioner added.
The IMD has issued 'yellow warning' (be aware) in Puri, Kendrapara Jagatsinghpur and Bhadrak districts over the next 24 hours. Similarly, for Saturday, it has issued an orange warning' (be prepared) in Balasore, Bhadrak, Kendrapara and Jagatsinghpur districts.
