The 1993 North Indian Ocean cyclone season was the period in which tropical cyclones formed within the north Indian ocean. The season has no official bounds but cyclones tend to form within this basin between April and December. There are two main seas in the North Indian Ocean — the Bay of Bengal to the east of the Indian subcontinent and the Arabian Sea to the west of India. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center releases unofficial advisories. An average of four to six storms form in the North Indian Ocean every season with peaks in May and November. Cyclones occurring between the meridans 45°E and 100°E are included in the season by the IMD.
Season summary
A below average total of five cyclonic disturbances were monitored during 1993, by the India Meteorological Department (IMD) and Joint Typhoon Warning Center (JTWC), compared to an average of fifteen.[nb 1]

On November 5, an area of convection organized into a tropical depression southwest of the southern tip of India. After moving towards the coast, it turned to the west, finally becoming a tropical storm on the 12th when it reached a favorable environment. After attaining cyclone strength on the 13th, it reached a peak of 90 mph winds. High vertical shear caused it to dissipate on the 16th over open waters.
A category 1 hurricane, it weakened over the sea near Sindh border due to high wind shear. However it caused massive rainfall and flooding in Karachi, Pakistan but Thatta and Badin districts were the worst affected where the cyclone killed 609 people and displaced some 200,000 others.[1][2]
