Track=Cyclone 01A 2001 track.pngFormed=May 21
Dissipated=May 28
3-min winds=115
1-min winds=110
Pressure=932A 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.

Depression

A depression that formed on June 12 in the Bay of Bengal lashed the Orissa coast until June 13. The storm had maximum sustained winds of 25 knots and a minimum pressure of 990 mb.
