[nb 1] The other two storms struck opposite sides of India, collectively resulting in 226 deaths after causing widespread flooding.
A low-pressure area moved across southern India, killing 388 people before taking an unusual track in the Arabian Sea.
The final storm of the season executed a rare loop in the Bay of Bengal before weakening and striking southern India in early December, killing seven.
[1] The basin's activity is sub-divided between the Arabian Sea and the Bay of Bengal on opposite coasts of India, and is generally split before and after the monsoon season.
In general, storms moved slower than average, and two of the cyclones took unusual tracks near land – one executed a rare loop in the Bay of Bengal, and another turned abruptly away from the Indian state of Gujarat.
[7] In early May, a westerly wind burst spawned two disturbances on both sides of the equator in the eastern Indian Ocean, in association with the monsoon trough.
[8] However, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on May 5 once the system became better organized amid low wind shear.
The system moved farther offshore on June 7 into the open Arabian Sea, where it interacted with the south-west monsoon and developed more convection.
[3] Moving northwestward, the system organized enough for the JTWC to classify it as Tropical Cyclone 02A about 160 km (99 mi) from the Oman coastline.
[1] Offshore Oman, the storm's rough waves disabled an oil tanker and damaged a fishing boat, killing one person in the latter incident.
Striking Oman, the storm produced significant rainfall totals well above the monthly average, peaking at 234 mm (9.2 in) in the Dhofar region.
[11] Flood waters washed away or damaged 1,068 km (664 mi) of roads and 21 bridges,[13] some of them dating back 2,000 years to the Roman era.
[11] The storm washed away the topsoil or otherwise wrecked 42,800 ha (106,000 acres) of crop fields, accounting for US$100 million in agriculture damage.
[1] A ridge to the east initially steered the system to the northwest, although an approaching trough turned it to the northeast, parallel to the coastline.
[18] Early on June 13, the JTWC assessed peak 1-minute winds of 85 km/h (55 mph),[3] and on the next day, the IMD upgraded the system to a cyclonic storm.
At 00:00 UTC on June 16, the IMD estimated peak 3-minute winds of 85 km/h (55 mph), around which time the storm turned back to the northwest.
[19] While the previous storm was paralleling the east Indian coastline, another disturbance formed off the west coast on June 15, also associated with the monsoon.
[3] The system moved to the northeast within the influence of the monsoon, and quickly intensified due to an anticyclone aloft providing favorable conditions.
[3] The storm turned northward and slowly weakened, degenerating into a remnant low over Rajasthan on June 20 before being swept up by an approaching trough.
Winds reached 85 km/h (55 mph) in Veraval, while heavy rainfall spread across the region, totaling over 300 mm (12 in) in some parts of Gujarat.
[1] South of the landfall point, high winds and waves washed 10 boats ashore near Mumbai, forcing the crews to be rescued by helicopters.
[23] Described by the JTWC as having "one of the most unusual tracks in North Indian Ocean cyclone history",[3] the storm originated as an area of convection that formed on October 14 in the southern Bay of Bengal.
Located south of a ridge, the system moved westward through an area of hostile wind shear, which prevented quick development by displacing the circulation east of the convection.
After the convection became more defined, the JTWC classified the system as Tropical Cyclone 06B on October 25 in the central Bay of Bengal.
[3] Moving through Bangladesh, the system quickly weakened and degenerated into a remnant low on October 29 over the Indian state of Assam.
[32] After a tropical depression from the Western Pacific dissipated over Myanmar, another disturbance formed in the extreme eastern Bay of Bengal on November 1.
[39] Originating from the monsoon trough, a well-defined circulation persisted on November 26 near the Andaman and Nicobar Islands, accompanied by a poorly defined area of convection.
[1] A strengthening ridge to the north turned the storm back to the west on November 30 into an area of lighter wind shear.
[3] Increased wind shear decoupled the convection from the center; the thunderstorms continued to the west-northwest and struck Andhra Pradesh, while the circulation turned southwestward.
[1][3] Ahead of the storm, about 200,000 people evacuated the Indian coastline and Very Heavy downpour stuck Tirupati and Chennai, following the damaging cyclone that struck Andhra Pradesh a month earlier.
