The Indian Meteorological Department issued a bulletin stating that a tropical depression had formed in the Bay of Bengal and was designated BOB 09.[5] The JTWC, released a TCFA on the system, stating that it could intensify further, because of very warm waters and low to moderate wind shear, designating it Invest 96B.[6] A day later, both the JTWC and IMD classified this low pressure as a "cyclonic storm" and it was named Mandous.[7][8] Mandous continued tracking westward, and later, attaining wind speeds of 65 mph (105 km/h; 56 kn), strengthened into a Severe Cyclonic Storm.[9][10] As it continued tracking westward, land interaction caused in to fall to Cyclonic Storm intensity. It later made landfall around Chennai, India as a Deep Depression. It fell to Depression intensity, and later degenerated into a remnant low.[11]

Regeneration

edit

On December 14, the remnants of Cyclone Mandous regenerated into a depression in the Arabian Sea, and it was called ARB 03.[12] The Joint Typhoon Warning Center dubbed it as Invest 97A. Although forecasted to quickly degenerate into a remnant low, ARB 03 intensified into a Deep Depression, according to the Indian Meteorological Department,[13] and the JTWC dubbed it as Cyclone 07A. After reaching peak intensity, the Low-Level Circulation detached from the associated convection, and wind shear increased, starting a weakening trend. It weakened into a low pressure area at 12:00 UTC on December 17.

Preparations

edit

In Puducherry and Karikal, colleges and schools were closed in anticipation of the storm.[14]

Impact

edit

Cyclone Mandous had a notable impact on several regions, particularly in southern India and Sri Lanka. In Chennai, approximately 200 trees were uprooted due to strong winds and heavy rainfall, causing disruptions to transportation and daily activities.[15] Power outages were reported in some areas, and local authorities worked to clear the debris and restore services.

In Anantapur, Andhra Pradesh, the cyclone resulted in damage amounting to ₹45 million (US$550,000).[16] The storm caused damage to infrastructure, crops, and property, affecting the local economy.

In Tamil Nadu, four fatalities were reported due to heavy rains and flooding. Several districts experienced widespread rainfall, leading to flooding and property damage. Emergency services were deployed to provide relief and assistance.

Off the coast of Sri Lanka, five fishermen went missing during the cyclone, prompting search and rescue operations. The storm also caused disruptions to fishing activities and damage to boats along the coastal areas.[17][18]

Overall, Cyclone Mandous had a significant impact on infrastructure, agriculture, and communities in the affected regions, with local authorities working to mitigate the damage and provide assistance.
