Understanding November Hurricanes: Frequency and Future…

Florida has experienced three hurricanes in November since records began: one in 1935, Hurricane Kate in 1985, and Hurricane Nicole in 2022. The potential for Hurricane Sara to impact Florida illustrates the growing trend of unusual late-season storms due to elevated ocean temperatures, highlighting the necessity for continued monitoring and preparedness as ocean heat content remains significantly above long-term averages.

As of now, Florida has recorded only three hurricanes making landfall in the month of November since observations began: an unnamed hurricane in 1935, Hurricane Kate in 1985, and Hurricane Nicole in 2022. These events are indeed rare; the recent projection indicates that Tropical Depression Nineteen could potentially develop into Hurricane Sara, marking the fourth hurricane to impact Florida in a single season, and the fourth to hit the state in November. This is a significant anomaly since hurricanes typically do not form during this time of year due to cooler ocean temperatures. However, current ocean temperatures in the Gulf and Caribbean remain unusually warm, increasing the chance of hurricane activity. The presence of these warm waters presents compelling evidence for changes in hurricane frequency, especially during the late season. Hurricane Nicole made landfall on November 10, 2022, as a Category 1 hurricane and resulted in extensive damage, highlighting that late-season hurricanes can still cause significant impact. Earlier this season, Hurricane Kate struck on November 22, 1985, reaching Category 2 strength, while the 1935 unnamed hurricane made landfall on November 4, achieving similar intensity. In addition to these hurricanes, numerous tropical storms have impacted Florida in November, further emphasizing the need to understand the risks associated with hurricane formation during this period. Furthermore, instances of other hurricanes developed but did not make landfall in the U.S. during November, such as Hurricane Eta in 2020, exemplifying the changing patterns in hurricane behavior in relation to warmer ocean temperatures.

Hurricane activity typically declines in late fall, with November characterized by cooler seas that hinder tropical storm development. However, recent observations have shown that ocean temperatures in the Gulf of Mexico and Caribbean remain elevated, contrary to historical trends. This increase in oceanic heat content boosts the likelihood of storm formation even as the season nears its conclusion on November 30. Understanding these changes is crucial, especially given the recent weather patterns that have led to hurricanes occurring at unusual times, such as November. The data collected from historical records show that while November hurricanes are infrequent, their impact can be substantial.

In summary, Florida’s history of experiencing hurricanes in November is minimal, with only three known occurrences. The potential development of Hurricane Sara could further alter this statistic, suggesting a possible shift in patterns due to climate-related changes in ocean temperatures. The documented impacts of hurricanes such as Nicole and Kate underline the importance of vigilance during this less common period of the hurricane season. The continuing trend of elevated ocean temperatures raises concerns about an increased frequency of late-season storms, necessitating further investigation into the implications of such climatic changes. The data reveal a significant relationship between warm ocean conditions and hurricane activity, warranting increased awareness and preparedness.
