The Alipore Meteorological Department informed on Tuesday that the cyclone formed over the Bay of Bengal is likely to weaken into a low-pressure system. As a result, a large amount of moisture will enter the state, causing continuous rainfall throughout the week. Heavy to very heavy rainfall is forecast in several districts on Thursday and Friday. The low-pressure system has also intensified disturbances in the sea. Fishermen have been warned not to venture into deep sea waters from Wednesday, May 28, until Saturday, May 31.
