Cyclonic Storm Ditwah was a weak but catastrophic tropical cyclone that brought heavy rain to Sri Lanka and Southern India in late November and early December 2025. The fourteenth tropical depression and fourth cyclonic storm of the 2025 North Indian Ocean cyclone season, Ditwah originated from a well-marked low before steadily intensifying into a cyclonic storm and making landfall in Sri Lanka. Ditwah then moved off Sri Lanka and entered the Bay of Bengal, where it re-intensified and began to parallel the Coromandel Coast of India. On 30 November, the system began to weaken due to increasingly unfavorable conditions. It lingered off to the coast of Tamil Nadu and Pondicherry. It weakened into a deep depression later that day, and by 2 December, the system further weakened into a depression before becoming a remnant low on 3 December. Most of the impact of Ditwah was concentrated in Sri Lanka. The storm caused heavy flooding and landslides, killing over 600 people and causing over US$1.6 billion dollars of damage in the country. It was the deadliest natural disaster in the country since the 2004 Indian Ocean earthquake and tsunami.
