Bhubaneswar: The prolonged weak monsoon caused by absence of southwesterly moisture laden wind from the Arabian Sea and strengthening of westerly or northwesterly wind flow over India is likely to continue till August 31, Siksha ‘O’ Anusandhan (SOA)’s Centre for Environment and Climate (CEC) said on Tuesday.
Numerical models indicated that a cyclonic circulation was likely to form over east central and adjoining north east Bay of Bengal off the Myanmar-Bangladesh coast on Wednesday and move towards north west bay on September 2, a CEC bulletin said.
Initially, it would move along south Odisha-north Andhra Pradesh coast before reaching central Odisha on September 4. Under its influence, a low pressure area is likely to form on the afternoon of September 3 or morning of September 4 over north west Bay of Bengal, it said adding it might intensify into a depression on September 5.
The bulletin said though light to moderate rainfall is expected to continue from September 2 over Odisha, widespread precipitation with heavy to very heavy rainfall at a few places could occur between September 4 and 7 over the state. There was probability of very heavy rain over coastal, north and western Odisha and widespread rainfall with heavy fall at some places in south Odisha, it said.
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 Odisha districts, the bulletin said.
