The monsoon trough is lying north of its normal position — from Rajasthan’s Ganganagar to the Bay of Bengal. A low-pressure area is lying over south-east and adjoining east-central Arabian Sea. It is likely to move slightly northwards during the next 48 hours and weaken thereafter.
A cyclonic circulation is also lying over south-east and adjoining east-central Arabian Sea at the level of lower and middle troposphere and an east-west shear zone that determines a change in wind direction and velocity and runs across peninsular India.
