Talking to reporters in Thiruvananthapuram after a meeting that reviewed the situation, he said though the exact number of stranded fishermen was yet to be known, the government initiative was to bring all of them to the shore without any delay.
Mr Vijayan said 70 fishermen in sea had already got in touch with rescue teams. But, the teams could not reach them due to inclement weather, he said.
Official sources said around 50 fishermen had already been rescued by the joint team of the Navy, the Air Force and the Coast Guard.
According to a rough estimate, nearly 200 fishermen here had gone out for fishing last day and yet to return.
Mr Vijayan said the state has requested the Defence Ministry to deploy more aircraft for rescue operations in view of the cyclone moving towards Lakshadweep.
The existing aircraft were not enough to tackle the problems in coastal Kerala and the archipelago.
He said rescue operations were also getting delayed as some of the fishermen in sea were not ready to return to shore by leaving their boats there.
"It is causing some problem. But, it shows that they are safe and efforts to supply food and water to them were on", he said.
The state government received the cyclone warning yesterday afternoon and started its relief and rescue measures immediately, he said.
Quoting information from the weather forecast, Mr Vijayan said the present situation was likely to continue till tomorrow.
However, he said at present the cyclone was moving 200 km away from the state's shore.
It was located 70 kms from Kerala's coast yesterday that triggered heavy rain and wind, he said.
Kerala had also sought the help of two Merchant Navy ships also rescued 10 fishermen from the sea.
Meanwhile, local people in the coastal towns of Poonthura and nearby areas of state capital blocked roads demanding urgent steps to rescue those stranded in the sea.
