A weak disturbance that formed east of Somalia was detected on May 18. By May 21 a tropical depression developed after the system formed a closed mid-level circulation. It tracked eastward across the Arabian Sea, but turned northward abruptly short of the Indian coast. Tropical Depression 01A became a tropical storm late on the 21st, and reached cyclone strength on the 22nd. While drifting northwestward on the 24th, Cyclone 01A became an intense cyclone with 125 mph winds over the open waters. Upper level shear weakened it to a tropical depression three days later. Moving northward, the storm briefly re-strengthened to a 65 mph storm before striking western India on the 28th and dissipating.
Ahead of the storm, all ports in Gujarat, including Kandla, one of the largest in the country, were closed as a precautionary measure.[1] Over 10,000 people were evacuated from coastal areas in the threatened region. Offshore, between 1,500 and 2,000 fishing vessels had lost contact with the mainland.[2]
