Despite a mid-season slowdown, the season ultimately highlighted significant developments in storm strength and weather patterns affecting the Atlantic.

**Record-Breaking 2024 Atlantic Hurricane Season Concludes with Surprising Quiet Period**
The 2024 Atlantic hurricane season saw unprecedented activity and unexpected lulls, raising questions about the impacts of climate change.
The 2024 Atlantic hurricane season has concluded, marking an unusually active year with a total of 18 named tropical storms. Among those, 11 intensified to hurricane status, with five reaching major hurricane levels, categorized as three or above. To put this into perspective, the average hurricane season typically sees only 14 tropical storms, seven hurricanes, and three major hurricanes.
In this season, records were both matched and surpassed; however, the activity was not consistent throughout. Specifically, after the record-setting Hurricane Beryl, which struck as the earliest Category 5 hurricane on July 2, there was a notable quiet period whereby only four named storms formed by September, and no major hurricanes developed in that timeframe. This lull was unexpected given the pre-season predictions that anticipated a season of above-average activity rooted in warm oceanic temperatures and the end of El Niño conditions, which traditionally suppress storm formations.
The context for this season reveals that hurricane patterns are influenced by multiple factors. It is speculated that changes in weather patterns over Africa may have affected storm genesis, pushing thunderstorms further north into areas less conducive for hurricane development. Instances of high Saharan dust also likely contributed to reduced activity. Nonetheless, the unusually high sea surface temperatures remained, indicating potential for powerful storms.
Interest surged again in late September as Hurricane Helene formed, rapidly intensifying and striking the Florida coast as a Category 4 hurricane. Helene produced catastrophic flooding and extensive damage across the southeastern United States and has been recorded as the deadliest hurricane since Katrina in 2005, accounting for over 150 fatalities.
Following Helene, a rapid succession of storms ensued, including Hurricane Milton, which exemplified rapid intensification with record wind speed increases. Milton, which reached Category 5, caused severe destruction in Florida, including tornado outbreaks. Ultimately, the season closed with Tropical Storm Sara, which significantly affected Central America without escalating to hurricane status.
As climate change continues to shape meteorological trends, analysis suggests that sea temperatures had risen about 1°C above average this season. This rise has been associated with increased wind speeds across all 2024 hurricanes; for instance, Milton's winds were estimated to be 23 mph stronger due specifically to climate change factors. Observations suggest a trend where while overall hurricane frequencies may not increase, the intensity and rainfall associated with those that form will continue to escalate, presenting more significant risks to affected regions.
