After a prolonged dry spell that brought hot, humid conditions across several parts of India, relief appears to be on the horizon as a fresh weather system develops over the Bay of Bengal.
The new system is expected to reinvigorate the southwest monsoon, leading to more widespread rainfall across large parts of the country beginning this weekend.
According to meteorologists, a low-pressure area forming over eastern India is gradually drawing moisture-laden winds from both the Bay of Bengal and the Arabian Sea, creating favourable conditions for a revival of monsoon activity.
WHAT IS HAPPENING OVER THE BAY OF BENGAL?
The Bay of Bengal, a key driver of India's southwest monsoon, is currently witnessing the formation of a fresh low-pressure area.
A low-pressure area is a region where air rises, allowing moisture-rich winds from the sea to converge, resulting in cloud formation and rainfall.
Satellite imagery indicates dense cloud cover and strong upward air movement associated with the system, which is strengthening as it gathers moisture and helps re-establish monsoon circulation over the Indian subcontinent.
The system is moving westward and is expected to approach Odisha before advancing into West Bengal over the next two to three days. As it progresses inland, rainfall is expected to first increase across eastern India before spreading to northern and central regions.
WHEN AND WHERE WILL IT RAIN?
Monsoon activity is expected to strengthen from July 19–20, with rainfall becoming more widespread through the following week.
Fairly widespread showers, accompanied by isolated heavy rainfall, are likely across Punjab, Haryana, Delhi, Uttar Pradesh, Bihar, Jharkhand, Odisha, Chhattisgarh, and West Bengal, providing much-needed relief from the prevailing heat and humidity.
The Himalayan states, including Uttarakhand, Himachal Pradesh, and parts of Jammu, could experience very heavy rainfall, prompting the need for caution in vulnerable areas.
Further west and south, rainfall is expected to increase more gradually.
Scattered showers are likely over Rajasthan, Madhya Pradesh, Gujarat, Maharashtra, and Telangana, while isolated rainfall along the west coast is expected to intensify over the weekend.
After July 20, rainfall across many parts of the country is projected to return closer to seasonal norms, although an exceptionally strong monsoon surge is not anticipated immediately.
A CRUCIAL MONSOON REVIVAL
The southwest monsoon remains critical for India's agriculture, water resources, and overall economy. However, this year's season has so far been marked by uneven and delayed rainfall.
The impact of the deficient monsoon is already evident in reservoir levels, particularly across southern and eastern India, where many major dams are holding significantly less water than both normal levels and the corresponding period last year.
The anticipated revival in rainfall is expected to improve water storage by replenishing reservoirs that are essential for irrigation, drinking water supply, and hydropower generation.
The developing weather system is also likely to reduce rainfall deficits across eastern and central India while providing relief from persistently high temperatures.
Although the renewed monsoon activity offers encouraging signs after the recent lull, sustained and evenly distributed rainfall across different regions will remain crucial for ensuring a successful monsoon season overall.
