**West Bengal Braces for Heavy Rainfall as Low Pressure Grips Bay of Bengal**

**Kolkata, India** – West Bengal is on alert for widespread rainfall and thunderstorms as a low-pressure system has formed over the northwest Bay of Bengal. This marks the 15th such system in the past 48 days. The India Meteorological Department (IMD) has issued warnings for heavy to very heavy rainfall in various districts.

Northern Bengal is expected to bear the brunt of the downpour today, with an “Orange” alert issued for Darjeeling, Alipurduar, and Jalpaiguri, indicating a high probability of very heavy rainfall. Kalimpong, Cooch Behar, and North Dinajpur are also under a “Yellow” alert for heavy rainfall. Residents in these areas can expect thunderstorms and gusty winds of 30-40 kmph.

While the low-pressure system is expected to move towards Odisha and Chhattisgarh, it will draw significant moisture into West Bengal, leading to the widespread rainfall.

Southern Bengal will experience a mix of cloudy skies and thunderstorms. Coastal and eastern districts, including Kolkata, Howrah, Hooghly, North and South 24 Parganas, East and West Burdwan, Birbhum, and Nadia, have a higher probability of thunderstorms and rainfall on Sunday. Similar conditions are expected on Monday and Tuesday across South Bengal, with the possibility of increased rainfall intensity and widespread thunderstorms. While the rain is expected to decrease from Wednesday, scattered thunderstorms and gusty winds will persist.

Kolkata is experiencing high humidity levels with temperatures above normal. While rain is expected from Sunday, citizens are waiting for much-needed relief.

The IMD has also issued warnings for heavy to very heavy rainfall in several other parts of India, including Arunachal Pradesh, Assam, Meghalaya, Bihar, Konkan, Goa, and Sikkim.
