New Delhi: Cyclone Fani is likely to develop into an “extremely severe cyclone” in two days, the India Meteorological Department has said. A warning has been issued to coastal areas of Tamil Nadu, Andhra Pradesh and Odisha to brace for strong winds, rainfall and rough seas.

The tropical cyclone could generate gusts of winds with speeds of up to 50-60 km per hour in the coastal areas of Tamil Nadu and Andhra Pradesh, the IMD said.

Till April 30, it is seen moving towards the Indian coast in the north-west direction before it turns away and moves north-east. It is still not clear where and when, if at all, the cyclone will make a landfall.

“It is difficult to accurately predict the trajectory of the cyclone more than five days in advance. As far as we can see, this cyclone is remaining over the sea. It will make landfall only after May 2. As of now, we can see the trajectory turning away from the land around April 30. Regular warnings are being issued and will continue to be issued,” a leading daily quoted IMD Director General K J Ramesh as saying.

On Monday and Tuesday, light to moderate rainfall is expected in some places in Kerala, north coastal Tamil Nadu, south coastal Andhra Pradesh. North coastal Andhra Pradesh and south coastal Odisha are expected to witness rainfall from May 2. Fishermen have been advised not to venture into deep sea areas.

The coastlines are also expected to experience high sea-waves. Chennai is likely to witness waves of height 2 to 2.5 metres on Monday and Tuesday, with the maximum wave height even reaching 4.8 metre.
