A cyclonic circulation has been persisting over the Gulf of Martaban near Burma and the adjoining North Andaman Sea over the past few days.
It has set up a trough that runs squarely across the Bay of Bengal, North Tamil Nadu, Kerala and reaches into the Lakshadweep area. This East – west Shear zone would set up instability in the atmosphere in the above mentioned areas and might Trigger violent Thunderstorms.
As such, this would translate into heavy to very heavy rain at isolated places over South Interior Karnataka, Rayalaseema, Coastal Andhra Pradesh, North Tamil Nadu including Chennai and Puducherry today.
The axis of South West monsoon trough at mean sea level passes through Ganganagar, Kaithal, Varanasi, Jamshedpur, Digha and hence southeastwards to north Andaman sea.
