Erstwhile very severe cyclone Lehar may have met with a meek end but some US models have put Bay of Bengal under fresh cyclone watch.
A causative system may get generated off the Sumatra (Indonesia) coast and head towards Sri Lanka and the adjoining south-east Tamil Nadu.
Climate Prediction Centre of the US National Weather Services has said that the system is likely to form during this weekend or into early next.
It has said that a new disturbance entering the Bay of Bengal has some potential for tropical cyclone development as it moves slowly westward.
As if on cue, India Met Department sees an ‘easterly wave’ affecting south peninsula from Saturday onwards.
Easterly waves are rain-generating waves in the atmosphere moving across the Bay which erupt in rain over Tamil Nadu and adjoining Kerala.
At times in the past, the rain head embedded in the wave has gone on to become low-pressure areas or depressions, even tropical cyclones.
Storm watchers put together the US and India Met Department views to surmise that some activity might get initiated early next week.
A leading storm tracker based in the US had already pointed to the possibility over a fresh buzz here getting louder as the week progresses. Meanwhile, India Met Department has said that rain or thundershowers would scale up over Andaman and Nicobar Islands from Sunday.
Many places over extreme peninsular India too will experience rain or thundershowers while it will be isolated over rest of adjoining region.
