The India Met Department has officially mounted a watch for a low-pressure area (‘low’), the first of the monsoon season, materialising in the Bay of Bengal over the next three days.
A preliminary cyclonic circulation is already persisting over the West-central Bay of Bengal, off Coastal Andhra Pradesh. This is expected to deepen into a ‘low’ that will help drive rains inland.
Sense of purposeThe ‘low’ will bring about an order and a sense of purpose to the monsoon thanks to its longer shelf life (than, for instance, a cyclone), leisurely movement and capacity to sustain rain for as long as it is active.
In the instant case, the India Met sees it crossing the Odisha coast and wading into Chhattisgarh and adjoining east Madhya Pradesh by July 1.
A storm tracker of the US Climate Prediction Centre expects it to continue to move along a west-northwest direction towards Rajasthan.
This is as best as it can get with regard to a ‘low’ moving inland from the Bay and tracking across the farming heartland of the country, ensuring an orderly progress of the monsoon.
It will bring rain into East and North-East India, Central India and adjoining West India (Gujarat) and North-West India during the weekend and into the next.
Fortnightly updateThe Met, Indian Council of Agriculture Research and the Central Institute for Dryland Agriculture had this to say on rainfall trend during the last two weeks:
