How many people were killed in the worst flooding in Sri Lanka in 56 years?
2003 North Indian Ocean cyclone season The 2003 North Indian Ocean cyclone season 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 is below the average of 5.4. 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.
1991 Bangladesh cyclone The 1991 Bangladesh cyclone (IMD designation: BOB 01, JTWC designation: 02B) was among the deadliest tropical cyclones on record. On the night of April 29, 1991, it struck the Chittagong district of southeastern Bangladesh with winds of around 250 km/h (155 mph). The storm forced a 6-metre (20 ft) storm surge inland over a wide area, killing at least 138,000 people and leaving as many as 10 million homeless.
