2024 North Indian Ocean cyclone season

The 2024 North Indian Ocean cyclone season is an ongoing event in the annual cycle of tropical cyclone formation. The season has no official bounds, but cyclones tend to form between April and December, with the peak from May to 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.

Cyclonic Storm Remal

After four months of inactivity, on 21 May, the India Meteorological Department (IMD) began monitoring a cyclonic circulation in the Bay of Bengal. Later that day, the Joint Typhoon Warning Center (JTWC) would also begin tracking the system, noting that it was likely to become a monsoon depression. The next day, the IMD noted that a low-pressure area had formed adjacent to the cyclonic circulation. Late on 23 May, the IMD upgraded the system into a well-marked low, stating that it was rapidly coalescing. The next day, the IMD stated that the depression formed in the Bay of Bengal, designating it as BOB 01. Subsequently, the JTWC issued a Tropical Cyclone Formation Alert (TCFA), noting the depression's broad circulation center and its improving rainbands. The next day, BOB 01 intensified into a deep depression. The JTWC would recognize the system as a cyclone, designating it as 01B. Soon after, the depression intensified into a cyclonic storm, causing the IMD to name it Remal.

On 25 May, the India Meteorological Department issued an emergency warning for the states of Nagaland, Manipur, Mizoram and Tripura due to the expected effects of the cyclone.

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 a new list from the Regional Specialized Meteorological Center in New Delhi by mid-2020. 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 other basins, then it will retain its original name. The next eight available names from the List of North Indian Ocean storm names are below.

Season effects

This is a table of all storms in the 2024 North Indian Ocean cyclone season. It mentions all of the season's storms and their names, duration, peak intensities according to the IMD storm scale, damage, and death totals. Damage and death totals include the damage and deaths caused when that storm was a precursor wave or extratropical low. All of the damage figures are in 2024 USD.
