The low pressure area formed over the north Andaman Sea and adjoining areas of south Andaman Sea and southeast Bay of Bengal has intensified into a depression over southeast Bay of Bengal close to the Andaman Islands, the India Meteorological Department (IMD) said on Saturday.
The depression is very likely to move northwest and intensify further into a deep depression over east-central and adjoining southeast Bay of Bengal by October 23 morning. Subsequently, it is very likely to re-curve gradually north-north-eastwards and intensify into a cyclonic storm over central Bay of Bengal by October 24 morning.
"Thereafter, it would continue to move north-northeastwards and cross the Bangladesh coast between the Tinkona Island and Sandwip around October 25 early morning," the weather office said.
