The 2003 North Indian Ocean cyclone season was the last season that tropical cyclones were not publicly labeled by India Meteorological Department (IMD). Also was mostly focused in the Bay of Bengal, where six of the seven depressions developed. The remaining system was a tropical cyclone that developed in the Arabian Sea in November, which was also the only system that did not affect land. There were three cyclonic storms, which was below the average of 4–6. Only one storm formed before the start of the monsoon season in June, although it was also the most notable. On May 10, a depression formed in the central Bay of Bengal, and within a few days became a very severe cyclonic storm. After it stalled, it drew moisture from the southwest to produce severe flooding across Sri Lanka, killing 254 people and becoming the worst floods there since 1947. Damage on the island totaled $135 million (2003 USD). The storm eventually made landfall in Myanmar on May 19. It is possible that the storm contributed to a deadly heat wave in India due to shifting air currents.
In late July, a monsoon depression moved across much of India, and another monsoon disturbance persisted off the coast of Pakistan. The interaction between the two systems resulted in heavy rainfall across the region, flooding dozens of villages. Monsoonal rainfall killed 285 people between Pakistan and India in the summer of 2003. In late August, another monsoon depression moved across northeastern India. A depression that struck Andhra Pradesh in India killed 21 people in early October. Later that month, a tropical depression crossed Thailand from the western Pacific Ocean, contributing to ongoing flooding that killed 19. Once in the Indian Ocean, this system struck southeastern India without causing much damage. The last system of the year was a cyclonic storm that struck southeastern India in December, killing 81 people and causing $28 million in damage (2003 USD).
