From tropical storms to frost advisories, this section provides an overview of the notable weather events that have occurred in Key West during November between 1990 and 2023.
Typhoons and Hurricanes
During the 1990s to 2010s, Key West experienced tropical storms and hurricanes in November, which caused significant damage and disruptions. For instance, Hurricane Kate in 1985 and Hurricane Michelle in 2001 brought heavy rainfall, strong winds, and storm surges to the area. More recently, Tropical Storm Eta in 2020 and Hurricane Ian in 2022 caused flooding and power outages in Key West.
Frost Advisories
While not as common as tropical storms, frost advisories have occurred in Key West during November on rare occasions. These events are often associated with cold fronts that bring chilly air to the region. In 2010, a frost advisory was issued for Key West on November 23rd, with temperatures dropping to 40°F (4°C). This event highlighted the potential for frosts in Key West, even in the midst of November.
Droughts
In addition to extreme weather events, droughts have also impacted Key West’s November conditions. The 1997-1998 El Niño event led to a severe drought in the region, which persisted until January 1999. More recently, a drought occurred in 2021, affecting the area’s water supply and agriculture.
Heatwaves
Key West is known for its subtropical climate, and heatwaves are common during the summer months. However, November heatwaves can also occur in the area. In 2019, a heatwave brought temperatures above 90°F (32°C) to the region, emphasizing the importance of heat safety measures.
- Typhoon Kate (1985): Brought heavy rainfall (15.1 inches) and strong winds (90 mph) to Key West on November 21st.
- Hurricane Michelle (2001): Caused a storm surge of 3-4 feet and flooding in coastal areas on November 5th.
- Tropical Storm Eta (2020): Brought heavy rainfall (7.3 inches) and strong winds (45 mph) to Key West on November 11th.
- Hurricane Ian (2022): Caused flooding and power outages in Key West due to strong winds (125 mph) and storm surges on September 28th.
The frequency and severity of weather-related events in Key West, FL, are influenced by various global and regional factors, including the El Niño-Southern Oscillation (ENSO), the Madden-Julian Oscillation (MJO), and the North Atlantic Oscillation (NAO).
Global weather patterns, particularly the ENSO and MJO, play a crucial role in shaping Key West’s November conditions. These phenomena impact the formation and movement of tropical cyclones, as well as the timing and intensity of cold fronts. Understanding these regional factors is essential for accurate weather forecasting and predicting potential hazards in the area.
The North Atlantic Oscillation (NAO) also influences Key West’s November conditions. During positive NAO phases, the subtropical jet stream is weaker, leading to reduced rainfall and cooler temperatures. Conversely, negative NAO phases result in a stronger subtropical jet stream, increasing the likelihood of heavy rainfall and warmer temperatures.
Final Conclusion
Ultimately, November weather in Key West, FL, is a reflection of the region’s subtropical location, where warmth and rainfall coexist in a delicate balance.
