1950s North Indian Ocean cyclone seasons

The years between 1950 and 1959 featured the 1950s North Indian Ocean cyclone seasons. Each season was an ongoing event in the annual cycle of tropical cyclone formation. The North Indian tropical cyclone season has no bounds, but they tend to form between April and December, peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. Below are the most significant cyclones in the time period. Because much of the North Indian coastline is near sea level and prone to flooding, these cyclones can easily kill many with storm surge and flooding. These cyclones are among the deadliest on earth in terms of numbers killed. At the time, only one RSMC, the India Meteorological Department (IMD), monitored the basin. However, in 1959, the Joint Typhoon Warning Center (JTWC) was founded, resulting in it releasing unofficial advisories for the basin.
