On 17 October 1975, the remnant of an earlier depression in the west central [[Bay of Bengal]] were moving towards India. Next day, the disturbance crossed the [[Andhra Pradesh]] coast and weakened into a low-pressure area. However, another low-pressure area formed in the east central [[Arabian Sea]]. The system was classified as T1 in the [[Dvorak technique]], suggesting it was a tropical storm. On 19 October, these two low-pressure circulations merged to form a depression centered near [[Maharashtra]] coast. The system intensity was classified as T2. The depression continued to intensify and moved west-northwestwards moving into the Arabian Sea. On the morning of the 20 October, the system intensified into a deep depression and was centered near 18.5°N, 70°E in Arabian Sea. The system intensity was classified as T3.5. By the noon, the deep depression had intensified into a cyclonic storm. It continued to move towards northwest. The next day it intensified in the severe cyclonic storm and moved towards north-northeast. On 22 October morning, it slightly weaken before making a landfall on coast about 10-15 km north of [[Porbandar]]. It moved northeast and weaken into cyclonic storm by 23 October, centred near [[Radhanpur]]. By the next day noon, it had weaken into depression on 24 October near [[Kota, Rajasthan|Kota]] in Rajasthan and then rapidly became a well-marked low-pressure area and moved northeastward before dissipating on 24 October evening near [[Uttar Pradesh]].<ref name=":0">{{Cite journal |last=Gupta |first=G.
