Fresh ‘low’ to liven up monsoon; season is far from over

A fresh low-pressure area is forecast to form over the West-Central Bay of Bengal off the Andhra Pradesh coast by Wednesday, livening up the monsoon activity with less than a fortnight for the season to end officially.

This is the latest indication that the June-September season is far from finished, and forecasts suggest surprises are in store for East, Central and West India. 

Fairly widespread to widespread rainfall with isolated heavy to very heavy falls likely over Maharashtra, with isolated extremely heavy falls over the ghat areas of Madhya Maharashtra and North Konkan) on Wednesday and Thursday. 

Rains for peninsula

The India Met Department (IMD) added that fairly widespread to widespread rainfall with isolated heavy to very heavy falls are likely over North Tamil Nadu, Andhra Pradesh, Telangana, and Interior Karnataka until Friday.

Separately, it has warned of the prospects of rise in water levels in the rivers of East Uttar Pradesh and Bihar until Friday due to enhanced rainfall over Nepal. 

Earlier, the Climate Prediction Centre of the US National Weather Service had hinted that the Andhra Pradesh-Odisha-Bengal coasts would witness fresh monsoon activity into September-end, if not beyond. 

The US agency forecasts suggest that the already flooded Gujarat, Saurashtra and Kutch may be likely bracing for even more rains during the rest of September, the last monsoon month. 

‘Shear zone’ back

The brewing ‘low’ off the Andhra Pradesh could also drag in the envelop of an East-West shear zone of monsoon turbulence with implications for parts of mainly Maharashtra, Andhra Pradesh and Telangana. Heavy to very heavy rainfall with extremely heavy falls is forecast over Madhya Maharashtra on Wednesday.

It would be heavy to very heavy over Vidarbha, Konkan, Goa, Coastal Andhra Pradesh and Rayalaseema while being heavy over East Uttar Pradesh, Gujarat, Marathawada, Telangana, Interior Karnataka, Tamil Nadu and Puducherry. 

Thunderstorms accompanied by squall (wind speeds up to 60 km/hr) may roll out over the Andaman & Nicobar Islands and lightning flashes could punctuate the Odisha skyline.

Strong winds may prevail over parts of the Arabian Sea, the Gulf of Mannar and the adjoining Tamil Nadu coast indicating the rejuvenated monsoon flows.

Withdrawal stuck

Squally weather conditions may prevail over the South Andhra Pradesh-North Tamil Nadu coasts as well as the Andaman Sea. Fishermen are advised not to venture into these areas.

Meanwhile, the hyper-active ‘low’ over North Madhya Pradesh that sustained rains over Central India has weakened in response to a situation where the flows are centering around the new ‘low’ in the Bay. 

Extended outlook from September 22 to 24 said that fairly widespread to widespread rainfall with isolated heavy falls is likely over East and North-East India, Central and adjoining Northern parts of the peninsula, while it would be fairly widespread along the West Coast.

The withdrawal of the monsoon, which should have begun from North-West India from September 1, may have been stuck even before it got initiated in right earnest.
