The 2020 North Indian Ocean cyclone season is an ongoing event in the annual cycle of tropical cyclone formation. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between March and December, with peaks in April and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
The scope of this article is limited to the Indian Ocean in the Northern Hemisphere, east of the Horn of Africa and west of the Malay Peninsula. There are two main seas in the North Indian Ocean — the Arabian Sea to the west of the Indian subcontinent, abbreviated ARB by the India Meteorological Department (IMD); and the Bay of Bengal to the east, abbreviated BOB by the IMD.
The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center releases unofficial advisories. On average, three to four cyclonic storms form in this basin every season.[1]

At 00:00 UTC on May 16, a depression formed in the southeast Bay of Bengal and was identified as BOB 01. Six hours later, the Indian Meteorological Department (IMD) upgraded the system to a deep depression. Around 15:00 UTC, the system further developed into Cyclonic Storm Amphan.[2] That morning, landslide and flooding warnings were hoisted for parts of India and Sri Lanka given expectations of torrential rainfall in the coming days.[3]
Storm names
Within this basin, a tropical cyclone is assigned a name when it is judged to have reached Cyclonic Storm intensity with winds of 65 km/h (40 mph). The names were selected by members of the ESCAP/WMO panel on Tropical Cyclones between 2000 and May 2004, before the Regional Specialized Meteorological Center in New Delhi started to assign names in September 2004. There is no retirement of tropical cyclone names in this basin as the list of names is only scheduled to be used once before a new list of names is drawn up. Should a named tropical cyclone move into the basin from the Western Pacific, then it will retain its original name. The next eight names from the list of North Indian Ocean storm names are listed below. Amphan is the last name from the original naming list published in 2004, while Nisarga is the first name from the new naming list published in 2020.
