Western disturbances continue to keep their date with North-West India in a procession, with the latest one lying straggled across North Pakistan and adjoining Jammu & Kashmir on Tuesday evening.

There’s a successor waiting further West over East Afghanistan, with a third one expected to come into the reckoning by February 28.

An offspring cyclonic circulation over south-west Rajasthan is setting up most of the violent weather over the western half of North India, while a line-up of troughs left behind by away-going disturbances is doing the honours over the eastern half.

Widespread rain

An India Met Department (IMD) update said that fairly widespread to widespread rain/snow along with isolated thunderstorms/hailstorms will break out over the hills over the next two days.

The IMD has warned of strong surface winds with speeds reaching up to 40 km/hr gusting to 50 km/hr over the plains, mainly across Punjab, Haryana, West Rajasthan, Uttar Pradesh and West Madhya Pradesh.

The East and North-East are in a ‘tinder box’-like condition with the troughs engineering incursion of a lot of moisture from the Bay of Bengal and wind confluence at the lower levels.

Troughs in East

Apec’s forecast

Meanwhile, a weather outlook for March to May issued by the Busan, South Korea-based Apec Climate Centre, has suggested that most parts of the country will receive normal rainfall except North Kerala and adjoining Coastal Karnataka.
