1998 Atlantic hurricane season

The 1998 Atlantic hurricane season was an active, catastrophic, and extremely deadly Atlantic hurricane season, which had the highest number of storm-related fatalities in 2 centuries and ranks as the second-deadliest season on record in the Atlantic, behind the 1780 season. Additionally, the season featured some of the costliest tropical cyclones ever in the basin at the time. The season had above average activity, due to the dissipation of an El Niño event and transition to La Niña conditions. It officially began on June 1 and ended on November 30, dates which conventionally delimit the period during which most tropical cyclones form in the Atlantic Ocean. The season had a rather slow start, with no tropical cyclones forming in June. The first tropical cyclone, Tropical Storm Alex, developed on July 27, one of the latest dates on record to see the formation of the first system in an Atlantic hurricane season. The season's final storm, Hurricane Nicole, became extratropical on December 1.

Several storms made landfall or directly affected land. Hurricane Bonnie made landfall in southeastern North Carolina as a Category 2 hurricane in late August, killing five people and causing about $1 billion in damage. Hurricane Earl caused $79 million in damage and three deaths after making landfall in Florida as a Category 1 hurricane.

The most notable storms were Hurricane Georges and Hurricane Mitch. Georges devastated Saint Kitts and Nevis, Puerto Rico and the Dominican Republic as a major Category 3 storm but peaked as a high-end Category 4 hurricane just before moving through many of the Caribbean Islands before affecting the southern US mainland, making its landfall near Biloxi, Mississippi, causing significant damage and at least 600 confirmed deaths. Mitch was a destructive Category 5 hurricane that affected much of Central America before making landfall in Florida as a tropical storm. It caused significant damage and killed at least 11,000 people in Central America, and was the second deadliest Atlantic hurricane in recorded history, behind only the Great Hurricane of 1780. Georges and Mitch caused $9.37 billion in damage and $6.08 billion USD) in damage, respectively. As a whole, the 1998 Atlantic hurricane season was, at the time, the second-costliest season on record, after the 1992 season.
