Gujarat continues to grapple with a severe crisis following devastating floods that have claimed over 30 lives and forced the evacuation of 18,000 people. Unfortunately, the situation shows no signs of easing. According to the latest updates from the Indian Meteorological Department (IMD), several states, including Uttar Pradesh, Chhattisgarh, and 14 others, are expected to experience heavy rainfall on August 30. Additionally, Gujarat, Odisha, and Karnataka are likely to face intense downpours on Friday.

Cyclonic Circulations and Their Impact
The IMD has attributed these weather conditions to cyclonic circulations forming in both the Arabian Sea and the Bay of Bengal. These circulations are expected to impact the Indian subcontinent from both the East and West, leading to widespread rainfall across several regions.
Weather Conditions in the East
The cyclonic circulation developing in the Bay of Bengal is predicted to move toward the coastal areas of Odisha and Andhra Pradesh, resulting in heavy rainfall across multiple regions in these states. The IMD has issued an orange alert for areas including Malkangiri, Koraput, Raighar, Gajpati, and Ganjam, indicating the potential for severe weather conditions.
Weather Forecast in the West
In the western part of India, pressure building in the Arabian Sea is advancing at a speed of 3 kilometers per hour, which may trigger severe rainfall in regions such as Rajkot, Jamnagar, Porbandar, Junagadh, Dwarka, and Kutch. The national capital, Delhi, has also experienced significant rainfall, recording 378.5 mm in August, the highest in the past twelve years.

The Arabian Sea, typically a calm geographical area, rarely experiences cyclones. The last notable disturbance occurred in August 1976, originating from the coastal areas of Odisha and weakening as it moved towards north-western India. Prior to that, a similar cyclonic circulation formed in 1964 along the coastal areas of Gujarat, which also weakened upon reaching the coastal plains.
In contrast, the Bay of Bengal, known for its volatile weather patterns, has seen 28 cyclones in August over the past 132 years, highlighting the distinct geographical differences between the eastern and western parts of India.
