Chennai: Perhaps in a first of its kind alert to Tamilnadu, giant waves measuring up to 3.5 metres (11.5 feet) along with storm surge are expected to strike Ramanathpuram and Kanyakumari coasts for two days, 21 and 22 April.

An advisory has been issued today by Tamilnadu Disaster Management and Mitigation Department along with Tamilnadu State Disaster Management Agency (TNSDMA). The matter has also been informed to the authorities of both the districts and officials have been put on high alert.

Speaking to reporters here, Tamilnadu Disaster Management and Mitigation Department Principal Secretary / Commissioner of Revenue Administration K Satyagopal, said, "Met office has predicted strong winds mainly from Southerly-southwesterly direction with speed occasionally reaching 35-45 kmph along and off Tamilnadu and Puducherry coasts. Indian National Centre for Ocean Information Services (INCOIS) has also issued a rough sea warning for south Tamilnadu coast."

"In wake of this condition, giant waves measuring between 2.5 and 3.5 metres (8.25 and 11.5 feet) along with storm surge will strike the southern coasts of Tamilnadu especially those in Ramanathapuram and Kanyakumari coasts from 8:30 am on 21 April and will continue on till 11:30 pm of 22 April. This will happen due to certain environmental changes in the region. The giant waves will strike intermittently with a time interval of 18 to 22 seconds," he added.

Sathyagopal further said, "The waves will reach much longer distances on the coast and are likely to submerge the shores. So residents need to take note of all information given by our department from now onwards. They are requested to remove all their belongings from beaches in these areas. As these waves will last for two days, they are also likely to flood the coastal villages. So, those residing close to shore need to be careful."

This phenomenon reminds of tsunami which struck our coasts all of a sudden on the wee hours of 26 December, 2004 morning. In that case, the giants waves lasted only for two hours. But the waves which are going to strike tomorrow are expected to last almost two full days. But officials asked residents not to panic.
