Two tropical cyclones were observed, well below the average of 5-6. One of which reached Cyclone strength.

Tropical Depression 01B

Basin=NIO
Track=Cyclone 01B 1990 track.pngFormed=April 17
Dissipated=April 18
1-min winds=30
Pressure=1000On April 17, a rapidly developing area of low pressure was being monitered in the Bay of Bengal. Only 12 hours after forming, a TCFA was issued for the low. The low was upgraded to Tropical Depression 01B shortly after. However, by the next day, the storm was beginning to dissipate as strong upper-level winds sheared the storm. 01B dissipated over open waters on April 18.

Tropical Cyclone 02B

Infobox Hurricane Small
Basin=NIO
Track=Cyclone 02B 1990 track.pngFormed=May 3
Dissipated=May 11
1-min winds=125
Pressure=916A tropical disturbance organized into a tropical depression on May 3 in the Bay of Bengal. Unlike its predecessor, conditions were favorable for continued development, and the system became a tropical storm on the 5th. A weakness in the subtropical ridge brought the system northwestward, where it quickly intensified to a cyclone on the 7th. It reaches a peak of 145 mph winds the next day, but it weakened to a 115 mph cyclone on the 9th when it made landfall on Andhra Pradesh, India. It dissipated 2 days later over central India. Massive evacuation efforts were placed for this cyclone, resulting in 150,000 people leaving the coastline. Strong flooding still caused 510 human fatalities, but the effect on agriculture was substantial. More than 100,000 animals were killed, and crop damage was estimated at $600 million (1990 USD). This was the worst Indian cyclone since 1977.

Tropical Depression 03B

Basin=NIO
Track=Cyclone 03B 1990 track.pngFormed=October 30
Dissipated=November 4
1-min winds=30
Pressure=1000A tropical depression, which formed on October 30, moved northwestward until hitting northern India on the 3rd.

Tropical Storm 04B

Basin=NIO
Track=Cyclone 04B 1990 track.pngFormed=October 30
Dissipated=November 4
1-min winds=35
Pressure=1000The final storm of the season began its life on December 13 in the southern Bay of Bengal. A break in the subtropical ridge brought the system northward, where it strengthened to a tropical storm on the 15th. The storm reached a peak of 50 mph winds, but upper level winds weakened it to a minimal storm on the 18th as it made landfall near the Bangladesh/Myanmar border.
