# Tropical cyclones in 2000

During 2000, tropical cyclones formed in seven different areas called basins, located within various parts of the Atlantic, Pacific, and Indian Oceans. A total of 140 tropical cyclones formed within bodies of water known as tropical cyclone basins, with 81 of them being further named by their responsible weather agencies when they attained maximum sustained winds of 35 knots (65 km/h; 40 mph). The strongest storm of the year was Cyclone Hudah, peaking with a minimum pressure of 905 hPa (26.72 inHg), and with 10-minute sustained winds of 220 km/h (135 mph). The highest confirmed number of deaths from a storm was from Typhoon Kai-tak, which killed 188 people, however, Leon–Eline may have killed up to 722 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.

## Global atmospheric and hydrological conditions

As the year began, a strong La Niña was peaking, with temperature anomalies going below −1.5 °C (−2.7 °F). NOAA's May hurricane outlook indicated that overall global conditions were conducive to increased activity in the North Atlantic basin. The La Niña began to weaken towards the latter part of 2000, with signs of weakening occurring as early as May. Astride crossed over from the previous year, dissipating on January 3.

## Summary
### North Atlantic Ocean

An average Atlantic hurricane season features 12 tropical storms, 6 hurricanes, and 3 major hurricanes, and features an Accumulated Cyclone Energy (ACE) count of 106. In 2000 in the North Atlantic basin, there were above-average numbers of named storms and hurricanes and an average number of major hurricanes. 2000 had an ACE count of 119, slightly higher than the average.
The season began with tropical depressions One and Two, both of which formed in June and affected no landmasses. Hurricane Alberto was the first named system of the 2000 season, intensifying into and peaking as a Category 3 hurricane. Alberto was the longest-lived storm of the 2000 Atlantic hurricane season. Four formed east of Florida, though it was not able to strengthen further and dissipated on August 11. Tropical Storm Beryl, Tropical Storm Chris, and Hurricane Debby all formed within a week of each other, with Beryl causing minimal damages in Mexico and Debby causing flooding throughout the Antilles. Tropical Storm Ernesto formed in the Main Development Region (MDR) and affected no landmasses, with Nine forming a week later in the Gulf of Mexico and making landfall on Sabine Pass. Hurricane Florence formed on September 10 and caused rip currents throughout the East Coast of the United States. Hurricane Gordon and Tropical Storm Helene formed on September 14 and 15 respectively, with both storms affecting the Gulf Coast and the East Coast. Hurricane Isaac was the second major hurricane of the season, peaking as a Category 4 hurricane and staying out to sea for most of its life. Hurricane Joyce peaked as a high-end Category 1 hurricane, with damage being limited to the Lesser Antilles. Hurricane Keith was the strongest storm of the season, forming on September 28. Keith rapidly intensified offshore of Belize, peaking as a Category 4 hurricane before weakening and making landfall. Keith caused $319 million in damage and caused 68 fatalities. Tropical Storm Leslie was a relatively weak and short-lived system, though its precursor caused $950 million in damages. Hurricane Michael formed on October 15 and transitioned to an extratropical cyclone just before making landfall in Newfoundland, causing moderate damage in the areas it affected. Tropical Storm Nadine formed days later, affecting no landmasses. The final system, an unnamed subtropical storm, formed on October 25 and affected New England and Atlantic Canada.
The season was not very destructive, causing a total of $1.296 billion in damage, most of which can be attributed to Hurricane Keith and Tropical Storm Leslie. Additionally, 105 people were killed, of which nearly two-thirds can be attributed to Hurricane Keith. The main reason for the lack of damage can be attributed to the lack of landfalling storms and the minimal impact from most of the storms that made landfall.

### Eastern & Central Pacific Ocean

An average Pacific hurricane season features 15 tropical storms, 9 hurricanes, and 4 major hurricanes, and features an Accumulated Cyclone Energy (ACE) count of 132. In 2000, there were a below-average number of hurricanes and major hurricanes, though there was an above-average number of named storms. As a whole, the season was below-average, having a total of 95 ACE and featuring 19 tropical storms, 6 hurricanes, and 2 major hurricanes. A majority of the storms were weak and short-lived.
The first storm, Hurricane Aletta, formed on May 22 and peaked as a Category 2 hurricane. Tropical Storm Bud was a relatively weak tropical storm, affecting portions of Mexico. Hurricane Carlotta was the strongest storm of the month, peaking as a high-end Category 4 hurricane. Carlotta caused 18 fatalities after sinking a Lithuanian freighter. Following Carlotta, Four-E, Tropical Storm Upana, and Five-E formed in July, all 3 of which were weak and short-lived.

## Systems

BOB 06, also known as the 2000 Sri Lanka cyclone was the strongest storm to hit Sri Lanka since 1978, being attributed to 9 deaths. 2 tropical depressions formed in the West Pacific before Soulik formed and rapidly intensified into a moderately strong typhoon. The year finished with Cyclone Ando, peaking offshore as an intense tropical cyclone.
