Fresh westerly system likely to get a look-in from today

A western disturbance expected to check into Northwest India is seen as making a pincer-like approach from across the border, starting Monday.

Global models show the system as impacting Jammu and Kashmir and southwest Rajasthan almost simultaneously on Wednesday.

TWO FLANKS

It would deepen the grip along separate northerly and southerly tracks during the next two days, growing later to cover the entire plains of the region by Thursday.

Significantly, the dominant westerlies associated with the system would also prevent a total ‘wash-down' of the peninsular south by a system developing concurrently over southwest Bay of Bengal.

The buzz in the seas would thus get muffled under the influence of the opposing westerlies, but Sri Lanka could come in the line of fire of the redirected system even as the rest of southwest Bay to the north and northwest gets cleaned up.

It is likely that southeast peninsular south (mainly southeast Tamil Nadu coast) may get impacted by the weather system, according to the forecast outlook.

WIDESPREAD RAIN

Meanwhile, fairly widespread rain or snowfall has occurred over Jammu and Kashmir, Himachal Pradesh and Uttarakhand until Sunday morning, an India Meteorological Department (IMD) update said in an afternoon bulletin.

The rain was isolated over west Uttar Pradesh.

The wet weather and snow was attributed to the influence of an incumbent but stubbornly slow western disturbance in its eastward movement until Saturday evening.

It is only overnight on Sunday morning that it has shown any urgency to get on with its easterly track, making the way clear for the successor system waiting across the border.

The incoming system would be active over the northwest region for at least the first three days of the week, IMD said.
