Two cyclonic circulations sprung up over the Bay of Bengal as a third showed up along the same latitude to the west, over north-east Arabian Sea on Friday.
Together, they are expected to oversee a brief monsoon rally over mainland India during the next few days.
These good tidings materialised as a competing tropical storm “Doksuri” in the East China Sea weakened and was close to a landfall over the southeast China coast.
But predecessors “Mawar” and “Guchol” had gone on to become intense typhoons in the northwest Pacific and ‘Talim’ stayed on for longer than thought.
Global forecasts, however, suspect that the emerging monsoon rally could get disrupted by July 7, when flows over the Arabian Sea would start weakening.
This is being attributed to the likely formation of yet another cyclone (typhoon) in the northwest Pacific.
The Climate Prediction Centre (CPC) of the US National Weather Services has put the ocean basin for cyclone formation watch during July 4-10.
None of the models are sure if the Bay of Bengal would throw up a weather system capable of sustaining the monsoon current into the plains of northwest during this period.
Still, the CPC feels that parts of southern peninsula would witness some rainfall due to ‘intra-seasonal variability’ in weather conditions.
It is being seen as a “perturbation” of an enhanced rain wave upstream over Africa.
Meanwhile, India Meteorological Department (IMD) has warned of heavy rainfall over places over Konkan, Goa, coastal Karnataka and Kerala for next two days.
The buzz in the Bay would bring about rain to many places over Orissa, south Chhattisgarh, Vidarbha and north Andhra Pradesh.
Thundershowers are likely over Jharkhand, Bihar, north Chhattisgarh, Madhya Pradesh, Madhya Maharashtra, Marathawada, interior Karnataka and south Gujarat.
An extended forecast valid until July 6 said that rain may continue to lash many places along west coast and east and adjoining central India.
The IMD saw an increase in rainfall activity over northwest India during this period.
