Siliguri, April 11: A 10-minute shower in the evening today brought the much-awaited relief to the people of Siliguri from the sweltering heat.
The rain, however, was devoid of its characteristic gusty wind prevalent at this time of the year and weather experts have ruled it out as a Nor’wester which, they said, will take another week to arrive.
“This is a scattered rainfall caused by incursion of some amount of moisture in the air. Some areas in Sevoke, Jalpaiguri and Sikkim have been receiving such showers for the past few weeks. We can expect few more such showers before the Nor’wester finally arrives,” said G.N. Raha, an official of the Regional Meteorological Office at Jalpaiguri.
Subir Sarkar, the in-charge of North Bengal University’s weather station, said the four to five millilitre rainfall in the evening was the result of local phenomenon. “This is definitely not a kalbaishaki which has not arrived in the region as yet,” he said.
With the average temperature in north Bengal reaching 35 degrees Celsius, rain has remained elusive since October except for a smattering here and there. Added to the heat is the regular power cuts.
Raha said: “Normally an anti-cyclonic circulation that forms over the Bay of Bengal pushes the moisture-laden winds towards north and south Bengal. Such a condition will form after one week. We can expect Nor’westers after that.”
The official, however, ruled out a heat wave-like condition in north Bengal like the one that has gripped south Bengal. “Although, westerly winds are blowing in the region, Darjeeling, Jalpaiguri and Cooch Behar districts will not experience a heat wave-like condition,” he said. The strong westerly winds blowing from north and western parts tend to push away rain-bearing clouds, causing the air to be dry and dusty.
