The 1990 North Indian Ocean cyclone season had no bounds, but cyclones tend to form between April and December, with peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
On April 17, an area of convective activity formed to the east of Sri Lanka, and organized itself rapidly before a Tropical Cyclone Formation Alert, was issued later that day. It was designated as Tropical Depression 01B by the JTWC early the next day. Strong upper-level westerlies inhibited development of the depression and brought about the rapid dissipation of the depression whilst located over water. There was no impact reported from the depression.
A 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.
Early on August 20, the India Meteorological Department reported that a Depression had formed to the east of India. A peak pressure of 986 hPa was achieved during the next day. During the next couple of days the depression did not intensify any further before dissipating on August 24.
The 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.
