Odisha prepares for third cyclone in three weeks
Odisha Disaster Management Minister Suresh Pujari said the state was taking precautionary measures following the impact of Cyclone Arnab in October and Cyclone Murasu earlier this month.
"Though the IMD has not forecast the landfall of the impending cyclone so far, we have put districts on alert keeping in view of the experience," Pujari said.
Cyclone Arnab made landfall in neighbouring Andhra Pradesh on October 28, triggering devastating floods in several southern Odisha districts. Cyclone Murasu subsequently brought rainfall to the region.
Authorities have been directed to remain prepared for possible heavy rainfall, flooding and evacuation requirements.
A 24-hour control room will remain operational in every district. Personnel from the National Disaster Response Force (NDRF), Odisha Disaster Rapid Action Force (ODRAF), Fire Services and emergency teams have been placed on standby.
In Ganjam district, Collector V Keerthi Vasan chaired a preparedness meeting and directed officials to take immediate precautionary measures.
"Drawing lessons from the impact of Cyclone Arnab and the subsequent floods, he instructed all departments to remain prepared to tackle the eventuality," a district official said.
The administration cancelled officials' leave over the weekend to ensure preparations were completed without delay.
Farmers have been advised to harvest their crops ahead of the expected rainfall on November 18 and 19.
Fishermen have also been instructed to return to shore by November 16, with the fisheries department directed to prevent fishing activities at sea thereafter.
District authorities have been asked to inspect cyclone shelters and ensure the availability of drinking water, food, lighting and sanitation facilities.
