Timeline of the 2018 Atlantic hurricane season

The 2018 Atlantic hurricane season was an event in the annual hurricane season in the north Atlantic Ocean. It as an above-average season for tropical cyclones for the third consecutive year. Though the season officially began on June 1, 2018 and ended November 30, 2018, dates adopted by convention and historically describe the period during each year when most tropical cyclones form,[1] it effectively started with the formation of Tropical Storm Alberto on May 25.[2] The season's final storm, Hurricane Oscar, dissipated on October 31.[3]

The year produced sixteen tropical depressions, all but one of which further intensified into named tropical storms. Of the fifteen named storms, eight developed into hurricanes, and two further intensified into major hurricanes, which are rated Category 3 or higher on the Saffir–Simpson scale. These two major hurricanes contributed to a majority of the season's severe destruction and loss of life, mainly in the United States.

Hurricane Florence formed near Cabo Verde on August 31, steered toward the west-northwest with little exception by a large area of high pressure to its north. The cyclone strengthened amid favorable environmental factors, becoming a Category 4 hurricane with maximum sustained winds of 150 mph (240 km/h) at its peak, but weakening occurred before Florence struck the coastline of North Carolina near Wrightsville Beach on September 14, with winds of 90 mph (150 km/h). Florence dealt a devastating blow to the Carolinas as it meandered across the region. Catastrophic, record-breaking flooding contributed to a majority of the storm's $24 billion in damage and 52 deaths, though significant storm surge along the coastline as well as an inland tornado outbreak caused severe damage as well.[4] In early October, Hurricane Michael formed in the western Caribbean Sea, resulting in significant flooding across Central America and Cuba. However, the majority of the storm's impact was felt in the Florida Panhandle, where Michael struck the coastline near Mexico Beach as a Category 5 hurricane, with winds of 160 mph (260 km/h). This constituted the first landfall of a Category 5 hurricane in the United States since Hurricane Andrew in 1992, and only the fifth in recorded history, alongside "Labor Day", Camille, and "Okeechobee". In addition, Michael became the third deepest by atmospheric pressure, the fourth strongest by maximum winds, and the latest Category 5 hurricane to strike the United States on record. Michael killed 74 people and caused $25 billion in damage.[5]

This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. It includes information that was not released throughout the season, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not initially warned upon, has been included.
