Centre for Environment and Climate (CEC) at SOA University here had also forecast formation of a cyclonic circulation over east central and adjoining north-east Bay of Bengal off the Myanmar-Bangladesh coast on Wednesday with movement towards north-west Bay on September 2. “A low pressure area is likely to form in the afternoon of September 3 or morning of September 4 over northwest Bay of Bengal and the system might intensify into a depression on September 5,” a bulletin of Centre for Environment and Climate (CEC) at SOA University here said.

While light to moderate rainfall may continue from September 2, widespread precipitation with heavy to very heavy rainfall is likely at a few places between September 4 and 7 over the state. There is also a probability of very heavy rain over coastal, north and western Odisha and widespread rainfall with heavy fall at some places in south Odisha. Extremely heavy rain is likely to occur on September 5 and 6 and the spell of rainfall in the ensuing week could offset the deficit rainfall in some of the districts, the bulletin added.
