2008 Atlantic hurricane season
The 2008 Atlantic hurricane season was a very active hurricane season with sixteen named storms formed, including eight that became hurricanes and five that became major hurricanes. The season officially started on June 1 and ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, the formation of Tropical Storm Arthur caused the season to start two days early. This season is the fourth most costly on record, behind only the 2004, 2005 and 2012 seasons, with over $47.5 billion in damage (2008 USD). It was the fourth busiest year since 1944 and the only year on record in which a major hurricane existed in every month from July through November in the North Atlantic. Bertha became the longest lived July tropical cyclone on record for the basin, the first of several long-lived systems during 2008. The season was devastating for Haiti, where over 800 people were killed by four consecutive tropical cyclones (Fay, Gustav, Hanna, and Ike), especially Hanna, in August and September. Hurricane Paloma's outer rain bands also made landfall over Haiti. Ike was also the most destructive storm of the season, as well as the strongest, devastating Cuba as a major hurricane and later making landfall near Galveston, Texas at Category 2 (nearly Category 3) intensity.
One very unusual feat was a streak of tropical cyclones affecting land. All but one system impacted land in 2008. The unprecedented number of storms with impact led to one of the deadliest and destructive seasons in the history of the Atlantic basin, especially with Hurricane Ike, as its overall damages made it the third costliest hurricane in the Atlantic.
==Seasonal forecasts==
Forecasts of hurricane activity are issued before each hurricane season by noted hurricane experts Dr. Philip J. Klotzbach, Dr. William M. Gray, and their associates at Colorado State University; and separately by NOAA forecasters.
Dr. Klotzbach's team (formerly led by Dr. Gray) defined the average number of storms per season (1950 to 2000) as 9.6 tropical storms, 5.9 hurricanes, and 2.3 major hurricanes (storms reaching at least Category 3 strength in the Saffir-Simpson Hurricane Scale). A normal season, as defined by NOAA, has 9 to 12 named storms, with 5 to 7 of those reaching hurricane strength, and 1 to 3 major hurricanes.
