The 2000 Sri Lanka cyclone (IMD designation: BOB 06 JTWC designation: 04B) was the strongest tropical cyclone to strike Sri Lanka since 1978. The fourth tropical storm and the second severe cyclonic storm of the 2000 North Indian Ocean cyclone season, it developed from an area of disturbed weather on December 25, 2000. It moved westward, and quickly strengthened under favorable conditions to reach top wind speeds of 75 mph (120 km/h). The cyclone hit eastern Sri Lanka at peak strength, then weakened slightly while crossing the island before making landfall over southern India on December 28. The storm degenerated into a remnant low later that day, before merging with another trough on the next day.
