Severe Cyclonic Storm ARB 01 Toward the end of April, an area of
convection persisted in the southern Bay of Bengal. It developed into a distinct
low-pressure area on May 1 over the body of water, but soon moved westward into India without developing. On May 4, the system emerged from
Kerala into the Arabian Sea, and soon after convection rapidly increased. Early on May 5, the JTWC classified the system as Tropical Cyclone 01A about 370 km (230 mi) west-southwest of
Kochi, India. Increased
wind shear, cooler waters, and dry air rapidly weakened the convection, exposing the center and causing the storm to deteriorate quickly into a depression. On May 10, the system degenerated into a remnant low off
Gujarat, without any discernible low-level circulation. While an active tropical cyclone, the storm dropped torrential rainfall to the
Lakshadweep group offshore western India.
Aminidivi recorded over three days, including in just 24 hours. The high rains cut communications from the island group to the mainland, and damaged 45 houses in conjunction with the winds. High waves sank 15 boats and one cargo ship while also causing erosion in Kerala. The storm killed nine people and caused ₹300 million
rupees ($6.7 million
USD). Despite the storm's ferocity, the government did not report about the cyclone for ten days, as they usually under report on landfalling storms. The cyclone caused heavy damage throughout
Rakhine State, destroying or heavily damaging 4,035 homes and leaving 25,000 people homeless. There was widespread crop damage, resulting in food shortages, and damaged roads disrupted subsequent relief efforts. Damage in Myanmar totaled over K621 million
kyat (US$99.2 million), making it the worst storm in the country since
1968, and there were 236 deaths. Although damage was heaviest in Myanmar, the cyclone's effects also spread into neighboring
Bangladesh, where strong winds knocked over trees and capsized two ships. Strong wind shear caused the depression to weaken, and the IMD downgraded it to a remnant low on June 13. On September 10, a low-pressure area developed within the monsoon trough in the extreme northern Bay of Bengal. Moving northwestward, it organized into a depression after it moved ashore, organizing over
West Bengal near
Kolkata. The system attained peak winds of despite being over land. Located within a
col, or weakness between ridges, the depression meandered over eastern India, weakening into a remnant low on September 15. Flash flooding in the Indian state of
Tripura killed four people and isolated about 55,000 people. Three people died in West Bengal, where floodwaters left about 650,000 people homeless in hundreds of villages. Flash flooding in Uttar Pradesh killed 33 people overnight on September 21. Cyclone Onil quickly attained its peak intensity on October 2 with winds of and a
barometric pressure of 990 mbar (hPa; ). However, dry air quickly entered the system, causing it to rapidly weaken to a depression just off the coast of Gujarat, India. Over the following several days, the system took a slow, erratic track towards the south-southeast. After turning northeastward, the system made landfall near
Porbandar on October 10 and dissipated shortly thereafter. Throughout southeastern Pakistan and northwestern India, thousands of residents were evacuated prior to the cyclone's arrival. In these areas, the storm produced moderate to heavy rainfall, peaking at in
Thatta,
Sindh, Pakistan. The drainage system of
Hyderabad sustained significant damage, leading to several protests and demonstrations by city residents. Offshore, 300 fishermen are believed to have gone missing during the storm.
Depression BOB 03/04 A low-pressure area formed in the Bay of Bengal on September 30 and gradually became more organized. It moved northwestward and developed into a depression on October 2. Without intensifying beyond winds of , the depression moved ashore Andhra Pradesh near
Kalingapatnam on October 4. It rapidly weakened into a remnant low and turned to the northeast. On October 7, the system re-intensified into a depression near
Bankura despite being over land, aided by moisture from the Bay of Bengal. Flash flooding caused landslides in
Kamrup, while regional and national roads were damaged or submerged. Over 15,000 people were forced to evacuate their homes to emergency shelters. Across the region, of crops were damaged, and a low-pressure area developed on November 1 in the southeastern Arabian Sea. The following day, a depression formed off the southwest coast of India. The disturbance tracked westward, weakening after passing south of Sri Lanka. On November 28, the JTWC classified it as Tropical Cyclone 05A, just 78 km (48 mi) from the equator. The IMD classified it as a depression the next day at 1.5° N, noting that "cyclogenesis ... at such low latitudes has not occurred in the past." After developing, the system moved northwestward due to a ridge over India. The IMD upgraded the depression to Cyclonic Storm Agni late on November 29 and further to a severe cyclonic storm the next day. The JTWC also upgraded Agni to the equivalent of a minimal hurricane, estimating peak 1 minute winds of . Wind shear and dry air caused the storm to weaken. After Agni turned westward, the IMD downgraded it to a depression and later remnant low on December 2, although the JTWC tracked it for another day, issuing their final advisory while Agni was about 450 km (275 mi) south-southeast of
Cape Guardafui—the easternmost point of the
Horn of Africa. The remnants moved ashore at eastern Somalia, before turning to the south and dissipating on December 5. == Season effects ==
