Low Pressure Over Bay May Trigger Extremely Heavy Rain In Odisha Next Week: CEC

Bhubaneswar: While the India Meteorological Department (IMD) has forecast heavy rain in Odisha on September 2 after a weak monsoon spell, SOA’s Centre for Environment and Climate (CEC) on Tuesday said the state may witness extremely heavy downpour on September 5 and 6 under the influence of a low pressure area, which may intensify into a depression, over Bay of Bengal.

“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. Numerical models, however, indicate that a cyclonic circulation is likely to form over Eastcentral and adjoining Northeast Bay of Bengal off the Myanmar-Bangladesh coast on Wednesday and move towards northwest Bay on September 2,” a CEC bulletin said.

Initially, it would move along South Odisha-North Andhra Pradesh coasts 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 Northwest Bay of Bengal, it said, adding that it might intensify into a depression on September 5.

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 is a 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 districts, the bulletin added.
