This is according to Sanib Banerjee, deputy director of IMD Kolkata in a conversation with the Hindustan Times. He says that the damage would be mostly seen in the coastal districts of East Midnapore and South 24 Parganas.?
IMD deputy director explained that due to the full-moon perigee, it would result in the rise of sea level by at least a metre -- a phenomenon that¡¯s known as spring tide and is seen during the full moon. This rise is over the normal high tide that the sea would witness on a daily basis.
When the moon aligns with the perigee and is at the closest point in the Earth¡¯s orbit, we witness the supermoon where the Moon appears quite larger than it normally does.?
However, during this time, the gravitational pull of the Moon is also the strongest, this causes the tides to rise much higher and much lower than normal. This phenomenon is known as a spring tide.?
The IMD deputy warned that the storm surge caused by the cyclone in East Midnapore district would be two to four metres whereas in South 24 Parganas it would be around one to two metres. This is over and above the spring tide.
