True to forecasts, a low-pressure area has formed over the west-central Bay of Bengal off the north Andhra Pradesh and south Odisha coasts this morning.

The ‘low’ makes monsoon flows to converge around it and carries the rain as it crosses the coast and tracks over land.

Trough over land

The ‘low’ has also opened up the all-important land-based trough from northwest Rajasthan and connecting with it.

The trough makes a custom-made path for the ‘low’ to mover land.

(This is distinct from the other offshore trough along the West Coast, which is crucial in terms of holding the Arabian Sea arm of the monsoon in good stead.

Today, it lay extended from south Gujarat coast to north Kerala).

The India Met Department said the land-based trough cuts through Madhya Pradesh, Chhattisgarh and Odisha.

The ‘low’ will bring moderate to heavy rain to all these regions and the surroundings as it moves over land.

Rain alert

This will expectedly provide for the base phase of the monsoon yet for central and east India during the ongoing season.

The Met Department has sounded a heavy rain warning over coastal Andhra Pradesh and Telangana. Heavy rain for Assam, Meghalaya, Saurashtra, Kutch, Konkan, Goa, coastal Karnataka, south interior Karnataka and Kerala.
