Low pressure system looms over West Bengal, threatening widespread rain in East India

A significant weather development is unfolding over the eastern regions of India, particularly in Jharkhand and Bihar, where a well-marked low-pressure area is forming over Gangetic West Bengal. This system is predicted to bring widespread rainfall to the area in the coming week.

Indian Meteorological Department experts anticipate heavy rainfall in the eastern and northeastern parts of India over the next three to four days, primarily due to the influence of this well-marked low-pressure system. The impact of this weather phenomenon is expected to result in substantial precipitation in these regions.

Monsoon withdrawal progress

The southwest monsoon, which marks the rainy season in India, is gradually withdrawing from the country. Currently, the withdrawal line passes through several regions, including Gulmarg, Dharamshala, Pantnagar, Etawah, Morena, Sawai Madhopur, Jodhpur, and Barmer. Favorable conditions are emerging for further withdrawal of the southwest monsoon from various areas, including Jammu-Kashmir-Ladakh-Gilgit-Baltistan-Muzaffarabad, Himachal Pradesh, Uttarakhand, West Uttar Pradesh, parts of Madhya Pradesh, Rajasthan, and some parts of Gujarat within the next two to three days.

Monsoon year of fluctuations

The monsoon season in 2023 has been marked by significant fluctuations. It began with a 9% rainfall deficiency in June, followed by a 13% excess in July, and then a 36% deficiency in August. September saw a return to excess rainfall, recording a 13% surplus. As October progresses, the summer rain-bearing system typically retreats from most parts of India, leaving behind sporadic spells of precipitation. However, this year's monsoon remains unpredictable, with two low-pressure areas forming over the Bay of Bengal and the Arabian Sea, continuing to bring moisture over the land.

Overall, the Indian subcontinent is experiencing a diverse and unpredictable monsoon season this year, with weather systems constantly shifting and impacting various regions in different ways.
