The Hindu Business Line : Bay hums again, but not for the last time yet

The Bay of Bengal has thrown up the latest `low' even as the immediately preceding system set up an interaction with a prevailing western disturbance to rain it hard over the plains as well as the hilly regions of North India.

Moving stealthily in the North Bay off the north Orissa-West Bengal coast, the new system is predicted to intensify and become more marked. Models predicate a west-northwest course for its onward movement, but some others suggest a north-northwest course.

MORE RAINS

Under its influence, Orissa, north coastal Andhra Pradesh and Gangetic West Bengal are likely to experience widespread rainfall with isolated heavy to very heavy falls during the next two days. The rains may extend to Chhattisgarh, Jharkhand and east Madhya Pradesh from Monday.

An unusually active western Pacific/South China Sea has had a cascading impact on the Bay waters downstream to the west, culminating in the formation of a string of `lows' that dumped their moisture over mainland India. The central and western parts of the country bore the brunt as rains pelted their way in.

MIGRANT SYSTEMS

Remnants of tropical cyclones, typhoons and super typhoons have spun their way into the Bay to set up the `lows' at almost one a week from July, said Mr J.V. Singh of the National Centre for Medium Range Weather Forecasting (NCMRWF).

The latest western Pacific system has been `Ioke,' which churned to become a super typhoon twice in its westward course over the open waters of central Pacific. It's now curling its way to the Japanese coast, but some models say it will re-curve and move northeast to spare the island nation the blushes.

TN COAST, NEXT?

Way down the road, there may be a monsoon system forming in the Bay in answer to Super Typhoon Ioke, according to Mr Jim Andrews of the US-based forecaster AccuWeather.com. "Don't look for any such thing for about two weeks," he said.

But a few models are already showing the possibility of `some energy' being astutely conserved off the Tamil Nadu coast seven days from now, Mr Singh said. But it is too early to take a final call; a prospective system could also settle to a little north along the Andhra coast.

LESS MARKED

Meanwhile, the depression-turned-`low' over Haryana has become less marked on Sunday, the NCMRWF said. The ongoing interaction with the western disturbance will continue to bring fairly widespread rainfall with isolated heavy to very heavy falls over the western Himalayas for another 36 hours.

Model predictions suggest that another western disturbance is likely to approach northwest India by Wednesday. But there was no word on whether the new `low' would go on to set up an interaction progressively with this system.
