The 2024 Atlantic hurricane season is the ongoing Atlantic hurricane season in the Northern Hemisphere. 

The season officially began on June 1, and will end on November 30. These dates, adopted by convention, historically describe the period in each year when most subtropical or tropical cyclogenesis occurs in the Atlantic Ocean. The first system, Tropical Storm Alberto, developed on June 19, making it the latest first named storm since 2014.The second storm of the season, Hurricane Beryl, was an extremely rare June major hurricane, the earliest Category 5 Atlantic hurricane on record, and only the second recorded in July. 

Next came Tropical Storm Chris, which formed on the last day of June and quickly made landfall in Veracruz. Activity then quieted down across the basin for most of July after Beryl dissipated, with no new tropical cyclones forming due to the presence of the Saharan air layer (SAL) across much of the Atlantic. In early August, Hurricane Debby developed in the Gulf of Mexico before making landfall in Florida and South Carolina. Shortly thereafter came Hurricane Ernesto, which impacted the Lesser Antilles, Puerto Rico, and Bermuda in mid-August. 

After an unusual lull in activity in late August and early September, Hurricane Francine formed in the Gulf, then made landfall in Louisiana. Later, on September 24, Hurricane Helene formed over the western Caribbean before moving toward the Big Bend region of Florida. It made landfall there on September 26, at Category 4 strength, before moving inland and dissipating over central Appalachia.On September 29, Hurricane Kirk formed in the Eastern Atlantic and rapidly intensified into a Category 4 hurricane before striking Europe as a post-tropical cyclone on October 9. 

On October 5, Hurricane Milton formed in the Gulf of Mexico and explosively intensified into the second Category 5 hurricane of the season, becoming the most intense Atlantic hurricane since Wilma in 2005 by barometric pressure and the most intense since Dorian in 2019 by wind speed. Milton later made landfall near Siesta Key, Florida on October 9, as a Category 3 hurricane.As of October 9, there are at least 335 fatalities and over $49.867 billion in damage, mostly from Beryl and Helene. So far, five hurricanes made landfall in the United States, three of them making landfall in Florida.

Seasonal forecasts

In advance of, and during, each hurricane season, several forecasts of hurricane activity are issued by national meteorological services, scientific agencies, and noted hurricane experts. These include forecasters from the United States National Oceanic and Atmospheric Administration (NOAA)’s Climate Prediction Center, Tropical Storm Risk (TSR), the United Kingdom’s Met Office (UKMO), and Colorado State University (CSU). The forecasts include weekly and monthly changes in significant factors that help determine the number of tropical storms, hurricanes, and major hurricanes.

According to NOAA and CSU, the average Atlantic hurricane season between 1991 and 2020 contained roughly 14 tropical storms, 7 hurricanes, 3 major hurricanes, and an accumulated cyclone energy (ACE) index of 72–111 units.
