Low Pressure Likely To Form Over Bay During Next 24 Hrs, Heavy Rain Predicted In Odisha

Bhubaneswar: The cyclonic circulation which was formed over north Coastal Andhra Pradesh & adjoining Westcentral Bay of Bengal on Friday now lies over northwest Bay of Bengal & neighbourhood and extends up to 5.8 km above mean sea level tilting southwestwards with height, a special bulletin of India Meteorological Department (IMD) said today.

Under its influence, a Low Pressure Area is likely to form over the same region during next 24 hours. It is likely to become more marked during subsequent 24 hours, it added.

The IMD has warned that under influence of gradual strengthening of monsoon flow and the anticipated low pressure area, rainfall activity is very likely to increase gradually from today and widespread rainfall with isolated heavy to very heavy rainfall with extremely heavy falls at one or two places is likely to occur during 6th to 10th August, 2022 over the districts of Odisha.

The IMD in its forecast for the next five days has said that while light to moderate rain/thundershower is very likely to occur at most places over the districts in Odisha, some places are likely to witness heavy to very heavy rainfall.
