The 2010 North Indian Ocean cyclone season was a below-average tropical cyclone season [nb 1] which featured the highest number of deaths since the 2010 season. Despite a lack of activity during the monsoon season from June to September due to a strong southwest monsoon, the season was the first to have five systems of at least cyclonic storm intensity form since the 1998 season. [1] The first storm of the season, Laila, formed on 17 May, while the final storm of the season, Deep Depression BOB 06, ultimately dissipated on 8 December.
Within the northern Indian Ocean, tropical cyclones were monitored by the India Meteorological Department (IMD) at the Regional Specialized Meteorological Center in New Delhi. The IMD designated tropical cyclones forming in the Arabian Sea with the prefix "ARB", tropical cyclones forming in the Bay of Bengal with the prefix "BOB" and tropical cyclones forming overland with the prefix "LAND". In addition, the United States Joint Typhoon Warning Center (JTWC) issued unofficial warnings within the region, with tropical cyclones forming in the Arabian Sea assigned the suffix "A" and tropical cyclones forming in the Bay of Bengal assigned the "B" suffix. The IMD used the IMD Tropical Cyclone Intensity Scale and measured average sustained wind speeds taken over a three-minute period, while the JTWC measured average sustained wind speeds taken over a one-minute period and used the Saffir–Simpson hurricane scale.
This timeline includes information from post-storm reviews by the IMD and the JTWC. It documents tropical cyclone formations, strengthenings, weakenings, landfalls, extratropical transitions, and dissipations during the season. Reports among warning centers often differ; therefore, information from both agencies has been included.
