Chennai, April 20 (IANS) Nine coastal states and islands have been warned about rough seas over the next two days, a senior Indian National Centre for Ocean Information Services (INCOIS)official said on Friday.
“There is no change in our warning issued on Thursday. As per our prediction, the rough sea condition will prevail in nine states during 21-22 April,” R.Harikumar, Scientist and Incharge Ocean State Forecasting, INCOIS told IANS over phone.
He said there is a possibility of the sea being rough near shore and also the low lying areas and some areas may experience surges intermittently from the morning of April 21 to the night of April 22 due to the effect of high period (18-22 seconds) swell waves, having 2.5-3 metre height.
The states and the union territories for whom the warning have been issued are Kerala, Tamil Nadu, Lakshadweep, Karnataka, Goa, Maharashtra, Gujarat, Odisha and West Bengal.
According to INCOIS, there is a possibility of surging of waves during the high tide times, in the low lying areas of the coasts during this period and both fishermen and coastal population are to be cautious during this period, INCOIS said.
INCOIS has also listed out precautionary measures: that plying of boats very near the coasts be avoided during this period as the coastal regions will experience its effect more; that boats may be anchored at a fair distance from each other to avoid collision and damage; that water- based recreational activity at the coasts be suspended during these events; and that taking out the boats from the shore to the sea and back be avoided.
It also said that the effect in the open ocean is likely to be minimal.
Harikumar said this is a rare phenomenon that occurs due to sustained wind in Southern Ocean.
He said INCOIS observation buoy in Seychelles has indicated high swells in the waves, which underscores the forecast for Indian states and union territories.
