1994 North Indian Ocean cyclone season

The 1994 North Indian Ocean cyclone season was the period in which tropical cyclones formed within the north Indian Ocean. The season has no official bounds but cyclones tend to form within this basin between April and December. There are two main seas in the North Indian Ocean — the Bay of Bengal to the east of the Indian subcontinent and the Arabian Sea to the west of India. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center releases unofficial advisories. An average of four to six storms form in the North Indian Ocean every season with peaks in May and November. Cyclones occurring between the meridans 45°E and 100°E are included in the season by the IMD.


During 1994 a below average total of eight cyclonic disturbances were recorded during the year, by the India Meteorological Department (IMD) and Joint Typhoon Warning Center (JTWC). This included six systems in the Bay of Bengal and two systems over the Arabian Sea. The first system occurred between March 21–24, but did not affect any land as it became the first cyclonic disturbance to form over the basin during March since 1939.

Depression BOB 01 (01B)

On March 20, the JTWC started to monitor an area of convection, that had developed to the south-west of the Andaman Islands. The system subsequently moved northwards and became the subject of a tropical cyclone formation alert, before it was declared a depression by the IMD late on March 21, as it peaked with 3-minute sustained windspeeds of 45 km/h (30 mph). The system was subsequently classified as Tropical Cyclone 04B by the JTWC during the next day, before it peaked with 1-minute sustained wind speeds of 75 km/h (45 mph). The system was subsequently last noted by the IMD during March 24, as it weakened into an area of low pressure, before the JTWC issued their final advisory early the next day as the system turned southwards over the sea.

Extremely Severe Cyclonic Storm BOB 02

A tropical depression formed in the southeastern Bay of Bengal on April 26. It followed a path and intensity very similar to the 1991 Bangladesh Cyclone, and became a tropical storm on the 29th. On the 30th it became a cyclone while turning north-northeastward, and on May 2 the cyclone reached a peak of 145 mph winds. It weakened to a 130 mph cyclone before hitting near the Bangladesh/Myanmar border later that day. Massive evacuation efforts and minor storm surge due to a low tide led to 285 casualties, a fraction of the similar 1991 cyclone that killed 138,000. It still caused flooding amounting to $125 million (1994 USD).

Severe Cyclonic Storm ARB 01

On June 5, a surface low organized into a tropical depression over western India. It moved to the west, becoming a tropical storm on the 7th and reached a peak of 50 mph later that day. The storm steadily weakened before dissipating over Oman on the 9th.

Severe Cyclonic Storm BOB 03

A tropical disturbance developed into a tropical depression over the western Bay of Bengal on October 28. It headed slowly westward, reaching tropical storm strength and a peak of 70 mph before hitting India and dissipating on the 31st.

Very Severe Cyclonic Storm ARB 02

An area of convection consolidated into Tropical Depression 5A on November 13 in the Arabian Sea. After moving northwestward, it turned to the west-southwest, strengthening to a tropical storm on the 16th and reaching a peak of 65 mph winds before hitting Somalia and dissipating on the 20th.

There were 30 deaths in Somalia.
