It is moving toward the Bay of Bengal.
Scientists think it may become stronger as it travels.
It could first become a depression and then a deep depression.
It might eventually become a cyclone, but that is not certain.
Warm seawater can give storms energy.

Met official in Calcutta
A meteorological official in Calcutta describing the likely movement of the system’s remnants.
“But there are other factors. Strong vertical wind shear, for example, is detrimental to a cyclone’s intensification. We are in the late monsoon, but there is a strong possibility of vertical wind shear.”
