Hudhud may bite

The ‘Hudhud’ cyclone, which is moving menacingly towards the east coast, could have a devastating effect when it crosses the coast on October 12, with high waves ranging from three to seven metres hitting Andhra Pradesh and Odisha coasts.

The Hyderabad-based Indian National Centre for Ocean Information Services (INCOIS), the nodal agency for providing ocean state forecasts for the Indian Ocean region, has said that the high waves, accompanied by high winds and ocean currents, are likely to hit the Indian coast .

Dr. Balakrishnan Nair T.M, head of Ocean Science and Information, INCOIS, said Hudhud could be as severe as Phailin, which hit the northern Andhra Pradesh and southern Odisha coasts in October last.

He said swells (remote waves coming from the present cyclonic area) had already started hitting the Visakhapatnam and Gopalpur (Odisha) coasts. Coastal locations from West Godavari to Srikakulam and from Ganjam to Jagatsinghpur in Odisha may face the maximum brunt at the time of landfall. The ocean currents along the coast are also likely to be quite high (140-190 cm/sec) during the same time.

Maintaining that INCOIS has received real-time wave and weather parameters such as wind, rainfall and atmospheric pressure from wave rider buoys and coastal automatic weather stations off Visakhapatnam and Gopalpur, Dr. Nair said the height of waves had started registering an upward trend and had reached 2.5 metres on Friday. They were expected to be around three times this value at the time of landfall. “According to the present model predictions, we will get very high waves towards the north of Visakhapatnam, which will be the right side of the track of the cyclone,” he added.

While the maximum wave height of 6.5 metres is expected to hit the coast at Visakhapatnam, it is likely to be in the range of six metres along the coast in Vizianagaram, five metres in Srikakulam and four metres in East Godavari and West Godavari districts.

The ocean current speeds are expected to reach 190 cm/sec in Visakahpatnam and Vizianagaram, 180 cm/sec in Srikakulam, 160 cm/sec in East Godavari and 140 cm/sec in West Godavari. They are likely to be 170 cm/sec each in Ganjam and Puri and 150 cm/sec in Jagatsinghpur.
