Core of Bay ‘low' may skip Tamil Nadu coast

A low-pressure area has been prowling the waters of southwest Bay of Bengal over the past couple of days, but it is initially seen as propelling itself towards eastern Sri Lanka coast.

Dry winds

Forecast analysis shows the winds over the southern peninsular India would be drier and colder northwesterly-to-northerlies blowing in from the plains of the north and west.

The wind pattern is forecast to shift to being rain-friendly easterlies only from the weekend, with scattered rains dropping over southern coastal Tamil Nadu.

This might translate into isolated showers over the interior parts of the State as well as the adjoining southern Kerala, even as the core of the erstwhile ‘low' wallows in the southern Arabian Sea.

India Meteorological Department (IMD) has said in its outlook bulletin that isolated rain or thundershowers may occur over extreme south peninsular India on Wednesday and Thursday but scale up thereafter.


Meanwhile, the weather over northwest India might turn a shade for the better with the arrival of a western disturbance marked by rising motion of air upfront, convection, build-up of clouds and snow and rainfall.

Growing cloudiness will cause minimum and maximum temperatures to rise by 2 to 3 degree Celsius over parts of northwest and central India.

Cold wave

This would in turn lead to abatement of cold wave conditions over some parts of these regions.

But fog to shallow fog would envelop parts of Uttar Pradesh, Bihar and some parts of sub-Himalayan West Bengal and Sikkim. This may progressively extend over Assam and Meghalaya also.

Forecast valid until Friday said scattered rain or snowfall would occur over Jammu and Kashmir, while it would be isolated over Himachal Pradesh and Uttarakhand.

Rain likely

Isolated rain or thundershowers are likely to unfold over the plains of northwest India from Thursday.
