Tropical cyclones in 2000

During 2000, 140 tropical or subtropical cyclones formed throughout the world. The cyclones originated in seven different areas called basins, where respective weather agencies named 81 storms when they attained maximum sustained winds of 65 km/h (40 mph). The strongest storm of the year was Cyclone Hudah in the south-west Indian Ocean, which attained a minimum pressure of 905 hPa (26.72 inHg), and 10-minute maximum sustained winds of 220 km/h (135 mph). Cyclone Paul tied Hudah's peak winds in the Australian basin.

The cyclones in 2000 produced significant impacts in parts of Africa, Asia, Oceania, and North America. In the western Pacific Ocean, floods produced by Typhoon Kai-tak and a nearby tropical depression led to the Payatas landslide that killed 218 people. In southeastern Africa, Cyclone Eline struck Madagascar and Mozambique after a period of above-normal rainfall, and the ensuing floods killed at least 700 people. The costliest storm was Saomai, which caused $6.3 billion in damage. The accumulated cyclone energy (ACE) index for the year 2000 (seven basins combined), as calculated by Colorado State University was 677.3 units.

There was an above-average number of storms during the year; the most active basin of the year was the Western Pacific, where a below-average 23 named storms formed. The Eastern Pacific and the North Atlantic were both relatively above-average, with 19 named storms forming in the Eastern Pacific and 15 in the North Atlantic. The Southern Hemisphere was also relatively average. Three Category 5 tropical cyclones were formed in 2000.
