An extraordinary meteorological event is currently unfolding across India, Pakistan, and Afghanistan. Defying the usual March heat, a massive 1,000-kilometer-long linear low-pressure system has stretched from Afghanistan deep into the Indian heartland. This rare Western Disturbance is drawing vast amounts of moisture from the Mediterranean, Caspian, and Black Seas, creating a powerful rain corridor.

Unlike typical disturbances that curve towards the northeast, this system is moving in a straight line, fueled by low-tropospheric cyclonic circulations over Rajasthan, Haryana, and Uttar Pradesh. As this eastward progression continues, states like Bihar, Jharkhand, and West Bengal are bracing for a significant increase in rainfall intensity.

Weather Forecast for Bengal:

The Alipore Met Department has warned of moderate to heavy thundershowers across North and South Bengal. Winds gusting between 40 to 60 km/h—and potentially hitting 70 km/h—are expected, along with isolated hailstorms. The most startling impact remains the dip in temperatures, with maximums expected to stay 2°C below normal. This atmospheric shift marks a stark departure from seasonal norms, turning a typically warm month into a spell of chilly, erratic storms.
