The 2024 Atlantic hurricane season, which officially concludes on November 30, has proven to be exceptionally active, recording 18 named storms, out of which 11 developed into hurricanes, with five reaching major hurricane status—those categorized as three or higher on the Saffir-Simpson scale. In contrast, an average season typically includes only 14 named storms, seven hurricanes, and three major hurricanes.
The pre-season forecasts hinted at an above-average activity year, with predictions labeling it "extraordinary." A notable highlight was Hurricane Beryl, which carved its place in history as the earliest category five hurricane, forming on July 2, and causing significant damage throughout the Caribbean and parts of southern Texas.
However, the season's progression diverged from expectations. After Beryl's rapid formation, activity declined sharply, with only four named storms and no major hurricanes forming until the end of September. This lull was unexpected, given the persistently high sea surface temperatures in the tropical Atlantic—typically a critical fuel for storm development—and the anticipated ending of El Niño conditions, which often inhibit hurricane formation.
Several factors contributed to this anomalous behavior. An unexpected shift in weather patterns across Africa resulted in rare precipitation in the Sahara, potentially affecting storm formation. Additionally, the presence of Saharan dust in the atmosphere may have inhibited the necessary thunderstorms that are precursors to hurricanes.
The Atlantic roared back to life in late September with Hurricane Helene, which rapidly intensified into a category four storm, resulting in widespread destruction from Florida to the Southern Appalachians. Helene's fierce impact marked it as the deadliest hurricane on the U.S. mainland since Hurricane Katrina in 2005, claiming over 150 lives.
Following Helene, the hurricane season surged with six successive storms, four of which underwent rapid intensification. Hurricane Milton was particularly noteworthy; it transitioned to category five status after a staggering wind speed increase of 90 mph within 24 hours. It ultimately brought tumultuous weather conditions, including a significant storm surge and multiple tornadoes, to Florida's west coast.
The final storm of the season, Tropical Storm Sara, brought heavy rainfall and resulted in severe flooding across Central America, showcasing the season's trend of devastating consequences.
Climate change remains a focal point of analysis regarding this hurricane season. Sea surface temperatures throughout the Atlantic are about 1C higher than the average from 1991-2020, fueling hurricane potency. Notably, studies indicate that maximal wind speeds across all 2024 Atlantic hurricanes were enhanced due to climate change, with Milton experiencing winds that were measurably stronger due to human influence.
While projections suggest an overall stagnation in cyclone frequency, scientists warn that storms that do form will exhibit heightened intensity and increased rainfall, heightening the risks of future hurricane seasons. As the Atlantic hurricane season concludes, the implications of this year’s severe weather phenomena resonate deeply, underscoring a troubling trajectory influenced by climate change.
