Amphan is the second most super intense cyclone —which has been formed in Bay of Bengal after 1999.
It is equivalent of the Category-5 hurricane on the Saffir-Simpson Hurricane Wind Scale, according to US space agency NASA. The space agency’s Aqua satellite passed over the Indian Ocean on Monday and gathered water vapour data that showed the intensity of powerful tropical cyclone.

Now, the Cyclone Amphan is currently over the Bay of Bengal and is barreling towards the coast of India and Bangladesh.

On Wednesday, it will make a landfall between West Bengal and Bangladesh during afternoon-evening time and will bring heavy rainfall in parts of Odisha, Bengal and Northeast.
