These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
Over 10,000 people were killed in India when Tropical Cyclone 03A brought a 4.9-metre (16-foot) storm surge to the Kathiawar Peninsula, inundating numerous salt mines.
A short lived depression in mid-October killed 122 people after triggering severe flooding in Andhra Pradesh.
It reached its peak intensity with winds of 130 km/h (81 mph) before making landfall near Chittagong, Bangladesh.
The storm reached its peak intensity with winds of 195 km/h (121 mph) shortly before making landfall near Porbandar in the Indian state of Gujarat.
[10] Shortly after 06B dissipated, the remnants of Tropical Storm Chip[11] triggered the development of a new cyclone over the Bay of Bengal.
The storm tracked along the edge of a subtropical ridge, reaching its peak intensity over open waters with winds of 140 km/h (87 mph).
The cyclone entered an area of higher wind shear shortly after and rapidly weakened before making landfall.
[13] The first cyclone in the region developed as a tropical disturbance on May 13 over the southern Bay of Bengal to the southeast of Sri Lanka.
[4] At 0700 UTC on May 17, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert (TCFA).
[15] At 0600 UTC on May 18, the first advisory on Tropical Cyclone 01B was issued by the JTWC,[4] while the IMD upgraded BOB 01 to a deep depression.
[15] Continuing on a northeasterly track, BOB 01 gradually intensified as it neared Bangladesh, strengthened into a cyclonic storm twelve hours later.
[14] Early on May 20, BOB 01 reached its peak intensity as a severe cyclonic storm with winds of 110 km/h (68 mph) and a barometric pressure of 972 mbar (hPa).
[4] Ahead of the storm, officials in Bangladesh relocated an estimated 650,000 people, resulting in a lower loss of life.
[5] Early the next day, the JTWC issued their first advisory on Tropical Cyclone 02A while the system was located about 740 km (460 mi) south of Masirah Island.
[15] Tropical Cyclone 03A brought a large storm surge of 4.9 m (16 ft) which devastated coastal communities and salt mines.
[23] An estimated 4,000 to 10,000 people were killed by the storm,[24][25] many of whom were salt mine workers who did not own a radio and received little or no warning of the cyclone.
The large loss of life was partially attributed to contractors who wanted to continue making profits and did not inform their workers of the approaching storm.
[28] Hundreds of other power transmission towers also fell, causing an estimated loss of Rs 10 billion for the Gujarat Electricity Board.
[15] In late September, an area of low pressure developed over the Arabian Sea within an east–west oriented surface trough while located about 740 km (460 mi) west of Mumbai, India.
Located within an area of moderate wind shear, the storm quickly weakened[32] and dissipated early on October 1.
[8] On October 8, the IMD began monitoring a tropical depression located about 835 km (519 mi) southwest of Mumbai.
The Indian Coast Guard immediately dispatched search and rescue ships and naval helicopters to find the missing people.
[7] The depression remained relatively weak, with winds peaking at 45 km/h (28 mph) before the storm made landfall near Narsapur in the Andhra Pradesh early on October 14.
[37] During the morning of October 14, overflow from a dam inundated the Srisailam powerhouse, forcing officials to shut down the plant.
[38] The following day, the water level of the dam continued to rise, leading to the evacuation of nearly 53,000 residents in the area.
[40] Early on October 28, the IMD began monitoring a tropical depression located about 555 km (345 mi) south-southeast of Visakhapatnam in the Andhra Pradesh.
[12] Shortly after reaching peak intensity, the cyclone entered an area of strong wind shear which caused convection associated with the storm to become dislocated from the center.
[12] Tropical Cyclone 07B produced a storm surge of 1.2 to 2.4 m (3.9 to 7.9 ft) which inundated coastal areas of Bangladesh,[50] killing 40 people and leaving at least 103 others missing.
A large area of rice paddies was lost due to flooding and numerous homes were buried in mud.
