The India Meteorological Department said Ockhi is now lying over the south-west Arabian Sea and slowly moving towards the Lakshadweep Islands. It is likely to have landfall in the early hours of Saturday, it added.
The Indian Navy and Indian Air Force were on Friday searching for at least 200 fishermen still missing in Kerala and Tamil Nadu after 18 returned safely following cyclonic storm Ockhi as torrential rains and gusty winds continued to pound the southern districts of the two states.
Four ships of the Indian Navy and four aircraft of the Indian Air Force have joined rescue operations to look for the missing fishermen.
Vizinjam coastal police said at least 57 fishermen, who ventured into the sea from Thumba and Pozhiyur areas on Wednesday, are yet to return. The police have established contact with some of them but a majority are still missing.
