Low Pressure Forms Over Bay Of Bengal, To Trigger Heavy Rainfall In Odisha

Bhubaneswar: A Low Pressure Area has formed today morning and now lies over Eastcentral & adjoining Northeast Bay of Bengal (BoB) with associated cyclonic circulation extending up to 7.6 km above mean sea level tilting southwards with height, informed a press release of the India Meteorological Department (IMD) issued here today.
