Typhoon Kalmaegi sends in ripples to revive monsoon in Bay

Some models still showed that the western and southern parts of Jammu and Kashmir would still receive passing light to moderate showers for the next two weeks.

Meanwhile, the Bay is readying to toss up the latest in the series of low-pressure areas under a gentle but unmistakable nudge from the east from the South China Sea.

Upper-level wave

An upper-level atmospheric wave that oversaw the vigorous monsoon over the Arabian Sea and the Bay of Bengal had transited to the South China Sea/West Pacific last week.

What it managed to come up with from the West Pacific was a ‘low’-turned-depression-turned typhoon Kalmaegi that has hit Hong Kong already and is heading towards the southwest coast of China.

The west-southwest track of Kalmaegi has already sent ripples back to the Bay of Bengal in the form of a fresh upper-level cyclonic circulation ahead of a fresh ‘low’.

India Met Department expects the ‘low’ to materialise by tomorrow but the buzz in the basin and the resulting trough has already triggered thundershowers over the eastern coast from Odisha down to Tamil Nadu.

Rains for South

According to the US National Centre for Environmental Prediction, the eastern coast and adjoining peninsular India may witness thundershowers over the next three to four days.

Hit-or-miss thunderstorms are also expected to line up to the rest of adjoining central India right up to west Madhya Pradesh, interior Maharashtra, and Karnataka.

But the south Andhra Pradesh coast and adjoining north Tamil Nadu coast (including Chennai) might witness enhanced rain or thundershower activity over the next couple of days.

Parts of the Northeastern States may also witness scaling up of rainfall from the impact of Typhoon Kalmaegi making a landfall over southwest China, not far from the rugged terrain towards the international border.
