The 1990 Andhra Pradesh cyclone was the worst disaster to affect Southern India since the 1977 Andhra Pradesh cyclone. The system was first noted as a depression on 4 May 1990, while it was located over the Bay of Bengal about 600 km (375 mi) to the southeast of Chennai, India. During the next day the depression intensified into a cyclonic storm and started to intensify rapidly, becoming a super cyclonic storm early on 8 May. The cyclone weakened slightly before it made landfall on India about 300 km (190 mi) to the north of Madras in the Tamil Nadu state as a very severe cyclonic storm with winds of 165 km/h (105 mph). While over land the cyclone gradually dissipated. The cyclone had a severe impact on India, with over 967 people reported to have been killed. Over 100,000 animals also died in the cyclone with the total cost of damages to crops estimated at over $600 million (1990 USD).
