Hurricane Lisa: A Cape Verde Storm with Varied Impacts




Hurricane Lisa 2010

Hurricane Lisa, a tropical cyclone that formed during the 2010 hurricane season, followed a sequence of Cape Verde hurricanes, originating as a tropical wave off the coast of Africa. This research article aims to provide an overview of Hurricane Lisa’s formation, track, and intensity changes, as well as its impacts on the affected areas. Furthermore, recommendations for hurricane preparedness and an interesting fact resulting from Hurricane Lisa’s occurrence are presented.

Introduction: In September 2010, a tropical wave developed into Tropical Depression Fourteen, later named Lisa. The storm’s path was characterized by an erratic movement due to an unusually weak subtropical ridge. This article explores the evolution of Hurricane Lisa and its consequences on the areas affected during its course.

Formation and Intensity Changes: On September 20, Lisa developed into a tropical depression southwest of Cape Verde. The depression briefly intensified into a tropical storm before encountering dry air, which weakened it to a depression. However, Lisa regained tropical storm strength on September 23 and underwent rapid intensification, becoming a hurricane on September 24 with peak winds of 85 mph (135 km/h). Subsequently, cooler waters and increased wind shear led to Lisa’s weakening, and it eventually degenerated into a remnant low by September 26.

Impacts on Affected Areas: Before Landfall: As Hurricane Lisa followed a track away from land, there were no direct impacts on coastal areas. However, increased wave activity and elevated rip currents were observed along several coastlines, leading to hazardous conditions for swimmers and beachgoers.

During Landfall: Due to Lisa’s track remaining over the open ocean, no land areas experienced the direct impacts of landfall. This spared populated regions from severe winds, storm surge, and inland flooding associated with landfalling hurricanes.

After the Hurricane: The remnant low of Hurricane Lisa continued moving northwest and northward, dissipating by September 29. The remnants had minimal impacts on land areas, primarily manifesting as increased cloud cover and scattered showers in some coastal regions.

Human Impact and Recovery Efforts: Fortunately, Hurricane Lisa did not result in any reported fatalities or significant damage to coastal communities. Since the storm remained offshore and weakened before approaching land, it spared populated areas from the most destructive effects. Thus, the cost of cleaning and rebuilding was relatively minimal, primarily involving minor repairs, debris cleanup, and restoration of services disrupted by scattered power outages.

Preparedness for Future Hurricanes: To protect against potential landfall by hurricanes similar to Lisa, the following recommendations are advised:

  • Stay informed about weather conditions by monitoring local meteorological services and official weather alerts.
  • Develop an emergency plan that includes evacuation routes, communication strategies, and necessary supplies such as food, water, and medications.
  • Secure your property by reinforcing windows, doors, and roofs, and clearing potential projectiles from the surroundings.
  • Familiarize yourself with flood zones in your area and take appropriate measures to protect your property.
  • Maintain a disaster supply kit with essentials like batteries, flashlights, first aid supplies, and a portable radio.

Interesting Fact: As a result of Hurricane Lisa’s occurrence in 2010, researchers gained valuable insights into the behavior of tropical cyclones originating from Cape Verde. This event highlighted the need for continued study and monitoring of Cape Verde storms to improve hurricane forecasting, preparedness, and response strategies in the future.

In conclusion, Hurricane Lisa, despite its relatively weak and erratic nature, had minimal impacts on the areas it encountered. The storm’s offshore track and subsequent weakening spared coastal communities from severe damage. However, it serves as a reminder of the importance of preparedness measures for potential future landfalling hurricanes.
