It will be another week when north-west India, adjoining central, east and southern parts switch back to a regime built around all-too familiar western disturbances and thunderstorms.

This also would mean that mercury climbs up significantly over these very regions, according to the US Climate Prediction Centre.

Exceptions could be the West Coast and the hills of north-west India.

During the last 24 hours ending Monday morning, most of the rain/thundershowers were confined to northeast India as the tail of a western disturbance wagged in the region.

Tail wagging

Agartala in Tripura topped the charts with 10 cm of rainfall during this period while Imphal recorded 5 cm and Kailashahar and Silchar 4 each, an India Met Department update said.

An extended outlook from the Met too suggested that the next western disturbance of any significance will move into northwest India around April 11 (Saturday).

The north-eastern States, isolated places in east and adjoining central India and extreme South India could be the other regions to get impacted as the westerly system moves across.

Weather warning

The weather warning from the Met for the next five days indicated that thunderstorms and heavy rain would mostly the east of India, and to some extent the plains of north-west India. Tuesday: Thunderstorms accompanied by squall/hail at isolated places over Himachal Pradesh, Uttarakhand, Punjab, Haryana, Delhi, Rajasthan, west Uttar Pradesh as well as east and northeast India.

Annual season

Meanwhile, the north-eastern States may be bracing for the onset of thunderstorm/squalls which rip through the region during this time every year.

Thunderstorms recorded during this season over Gangetic West Bengal, Bangladesh and north-east India are the most severe and destructive among such events recorded over the entire subcontinent.

These storms are accompanied by strong surface wind squalls, torrential rainfall, large hail, and they often convert into tornadoes at times leaving behind a trail of destruction in their path.

These phenomena disrupt normal life every year, and cause widespread human and animal fatalities and severe damage to property.
