Rain and snow-triggering and warmth-inducing western disturbances are forecast to liven up weather over North India for the next week, an India Met Department (IMD) said on Wednesday.

In the process, prevailing cold wave conditions over the rest of the North will get pushed down towards Maharashtra in the main, and with lesser intensity to the rest of Peninsular India as well.

Cold, ground frost

The 24 hours ending on Wednesday morning have already seen cold wave conditions establish at isolated pockets over Vidarbha and North Madhya Maharashtra. Ground frost was reported from farther North in Punjab.

The IMD outlook favoured cold wave conditions to continue to hold over parts of Vidarbha during the next two days and at isolated pockets over North Madhya Maharashtra from Thursday.

As for western disturbances, a remnant of a prevailing one — parked over the North-Eastern States — was in the process of moving away East and out of the country.

Light rain/snow was observed at isolated places over Jammu & Kashmir, Himachal Pradesh and Arunachal Pradesh during the 24 hours ending on Wednesday morning.

More disturbances seen

A follow-up disturbance had called in already and lay spread-eagled over North Pakistan and adjoining Jammu & Kashmir. It will trigger fairly widespread to widespread rain/snowfall over the hills from Thursday to Sunday.

Fairly widespread rainfall is likely over Punjab on Friday and Saturday. Isolated to scattered rainfall over the rest of the plains of North-West India from Thursday to Sunday.

The IMD indicated that the peak weather activity may unfold on Saturday when heavy rain/snow is forecast at isolated places over Jammu & Kashmir and Himachal Pradesh.

Meanwhile, yet another western disturbance could affect the Western Himalayan region from Tuesday next (January 15), bringing scattered to fairly widespread rain/snow over the region.

Easterly wave likely

Alongside, the IMD has forecast a fresh round of rainfall over Andaman & Nicobar Islands and the southern-most parts of the peninsula. It could likely result from an easterly wave being sent down across the Bay of Bengal.

It was only earlier in the week that erstwhile cyclone ‘Pabuk’ had entered the Andaman Sea, crossed the islands as a deep depression, setting off moderate to heavy showers.

An US agency forecast has maintained the outlook for a fresh buzz in the area as a likely storm crosses in from the South China Sea and enters the Andaman Sea and adjoining South Bay.

On Wednesday, its updated forecast suggested that the emerging low-pressure system may head straight towards the southern part of Sri Lanka by January 26.
