2024 North Indian Ocean Cyclone Season Overview

Introduction

The ongoing 2024 North Indian Ocean cyclone season typically sees cyclones forming between April and December, peaking from May to November. This season encompasses the Arabian Sea (ARB) to the west and the Bay of Bengal (BOB) to the east. The India Meteorological Department (IMD) is the official Regional Specialized Meteorological Centre for this basin, with the Joint Typhoon Warning Center providing unofficial advisories. On average, three to four cyclonic storms form in this basin each season.

Systems

The Joint Typhoon Warning Center (JTWC) and the India Meteorological Department (IMD) started keeping an eye on a cyclonic circulation in the Bay of Bengal on May 21, following a four-month hiatus. The system was upgraded to a well-marked low by May 23 by the IMD, which quickly came together and was named BOB 01 the next day.

Storm names

When tropical cyclones in the North Indian Ocean basin achieve cyclonic storm intensity, or winds of 65 km/h (40 mph), they are given names. The Regional Specialized Meteorological Center in New Delhi compiled a list from which the names were selected. In contrast to some other locations, names for cyclones are used once before being retired and replaced with new ones. A cyclone that moves from another place into this basin keeps its original name. The following eight names on the list are: Senyar, Ditwah, Montha, Asna, Dana, Fengal, Remal, and Asna.
