Tropical Storm One (1B)

|1-min winds=35 |3-min winds=35 The first storm of the season began its life on October 10 in the Bay of Bengal. It executed an anticyclonic loop to the west, and became a tropical storm before hitting eastern Sri Lanka on the 17th. It continued westward, and ultimately dissipated over the Arabian Sea on the 20th.

Tropical Storm Two (2B)

Tropical Storm Three (3A)

|1-min winds=35 |3-min winds=25 The monsoon trough spawned a tropical depression off the western Indian coast on November 12. It tracked generally northwestward, slowly organizing into a tropical storm on the 17th. The storm turned to the northeast, where it dissipated over the northeastern Arabian Sea.

Tropical Storm Four (4B)

|1-min winds=35 |3-min winds=40 A storm of unknown intensity persisted in the western Bay of Bengal from December 3 to the 7th, remaining well offshore of any landmass.
