These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.

An average of four to six storms form in the North Indian Ocean every season with peaks in May and November.

Deep Depression Ten formed in late October, and Severe Cyclonic Storm Harriet crossed over from the Western Pacific at around the same time.

It then crossed India and resurfaced in the Arabian Sea early on May 18, also turning northwest in the meantime.

The storm spent the rest of its lifetime slowly moving northwest as a tropical depression, eventually dissipating on May 22 a few hundred kilometers south of Pakistan.

The storm made a tropical depression-strength landfall on western Myanmar on May 25 and quickly dissipated afterward.

After maintaining its intensity for two days, the storm dissipated a few miles off the east coast of Oman.

it maintained its intensity for one day, then made a tropical depression-strength landfall on southern East Pakistan which caused its dissipation less than six hours later.

[7] It formed on July 11 as a tropical depression, moving west-northwestward in the northern Bay of Bengal.

The tropical depression later dissipated on July 15, and generally moved west-northwestward in its eight-day lifetime.

After making landfall in Thailand, the system continued westward, then curved to the northeast, probably regathering strength and making landfall near Chittagong in East Pakistan on October 30 before rapidly dissipating.

[13] The destruction from Tropical Storm Harriet took the lives of at least 769 residents of Thailand's southern provinces.

Damage at the time was estimated to be over $34.5 million (1962 USD) to government buildings, agriculture, homes and fishing fleets.

[17] The storm moved from east to west and made a Tropical Storm-equivalent landfall on eastern India.
