In a rare August weather event, Cyclone Asna is forming over the Saurashtra-Kutch region of Gujarat. The India Meteorological Department (IMD) has issued a bulletin predicting that a deep depression in this area will soon intensify into a cyclonic storm. This development is significant as it marks the first cyclonic storm to develop over the Arabian Sea in August since 1976.
Cyclone Asna's Expected Path
The deep depression over Saurashtra and Kutch is likely to move west-southwestwards and is expected to emerge over the northeast Arabian Sea, near the Kutch region and adjoining Pakistan coasts. Once it strengthens into a cyclone, it will be named Asna, a name provided by Pakistan. According to IMD forecasts, even if the depression intensifies into a cyclonic storm, it is unlikely to impact the Indian coastline. Instead, the cyclone is expected to travel from the Saurashtra-Kutch region of Gujarat towards the Oman coast.
Rare Cyclonic Activity in August
Cyclonic storms in the Arabian Sea during August are rare. According to the IMD, only three such storms have developed between 1891 and 2023. The last time a similar event occurred was in 1976. Before that, a brief cyclone formed near South Gujarat in 1964 but weakened near the coast. Another instance in 1944 saw a cyclone intensify after entering the Arabian Sea but eventually weaken mid-sea.
Unusual Characteristics of the Current Storm
The IMD has pointed out that this storm is unusual due to its consistent intensity over the past few days. A scientist from the IMD explained that the tropical storm is positioned between two anticyclones-one over the Tibetan Plateau and another over the Arabian Peninsula-which is contributing to its steady strength.
The deep depression has already caused heavy rainfall in the Saurashtra and Kutch regions, leading to flood-like conditions in several areas. According to IMD data, these regions have received 799 mm of rainfall from June 1 to August 29 this year, which is 86% more than the normal average of 430.6 mm for this period.
Historical Context and Impact
The IMD notes that over the last 132 years, there have been 28 similar systems in August over the Bay of Bengal. The persistence of the current deep depression is noteworthy given historical patterns. Despite the deep depression potentially turning into a cyclonic storm, it is unlikely to have a significant impact on India's coastline. The storm is expected to move from Gujarat's Saurashtra-Kutch region towards Oman's coast.
Additional Weather Developments
Apart from Cyclone Asna, the IMD also observed another low-pressure area forming over the central and north Bay of Bengal. This system is likely to move west-northwestwards and may intensify into a depression by Sunday as it heads towards the north Andhra Pradesh and south Odisha coasts.
This rare weather phenomenon highlights how unique climatic events can still occur, even when historical trends suggest otherwise. Residents in the affected areas are advised to stay informed and prepared as the situation develops.
