The mountainous interior contrasts with the coastal plains and banana plantations. The island experiences a warm tropical climate that enabled it to become a major European tourist destination. Its strategic location made Tenerife an important link between Europe, Africa and the Americas throughout its history.
Tenerife has a long history of sporadic tropical storms and cyclones originating off the West African coast, which have caused periodic devastation. In 1826, a major hurricane destroyed the main port city of Santa Cruz de Tenerife. More recently in November 2005, Tropical Storm Delta affected the Canary Islands, causing significant damage and loss of life on Tenerife. This article analyzes the impacts, implications and lessons learned from Tropical Storm Delta, the worst natural disaster in recent history on the island of Tenerife.
Tropical Cyclone Basics
Tropical cyclones are rapidly rotating storm systems characterized by a low-pressure center, numerous thunderstorms, heavy rains and strong winds. These storms thrive on warm tropical oceans and require specific environmental conditions, including sufficient sea surface temperatures above 26 °C to a depth of 50 meters to drive convection and fuel the hurricane.
Tropical cyclones form over tropical and subtropical waters typically between 5-15° N and 5-15° S latitudes, within regions known as hurricane basins. In the North Atlantic basin, which includes the Caribbean Sea and Gulf of Mexico, these storms are referred to as hurricanes. The official Atlantic hurricane season lasts from June 1 to November 30, with peak activity between late August and October.
Tropical cyclones can unleash devastating winds, torrential rain, flooding, high surf and storm surges on coastal areas. The strong winds can damage homes and buildings, down trees and power lines and destroy crops. Storm surges can penetrate far inland and cause severe flooding. The heavy rainfall often triggers flash floods and landslides. Weaker tropical cyclones get classified as tropical depressions, storms or hurricanes depending on wind speeds.
The Canary Islands have experienced various tropical cyclones originating off the West African coast. In 1826, Santa Cruz de Tenerife got struck by a devastating hurricane that damaged over 500 houses. Hurricane Delta in 2005 was the first tropical storm in the Canary Islands since records began in 1848. Scientists predict tropical activity in the North Atlantic basin will increase over the 21st century due to climate change warming tropical ocean waters. Preparedness and early warning systems remain vital to reduce risk.
Tropical Storm Delta (2005)
In late October 2005, Tropical Storm Delta formed unusually far east over the Canary Islands, bringing torrential rains, widespread flooding and strong winds that caused substantial damage and over a dozen fatalities on the island of Tenerife.
Delta originated from an area of low pressure that formed on October 26 over the eastern Atlantic Ocean. Fueled by warm ocean temperatures, the storm quickly organized and strengthened while moving slowly towards the northwest. On November 28, Delta made landfall over Gran Canaria as a moderate tropical storm with winds up to 100 km/h. The storm continued its trajectory, passing directly over Tenerife on November 29.
Delta brought torrential rains to Tenerife, with precipitation totals exceeding 200 mm in the mountains and over 350 mm recorded at Izaña Observatory. The heavy rainfall triggered massive flash flooding and landslides across the island. Mudslides from Teide National Park descended into populated areas, burying cars and homes under several meters of debris. The resort town of Los Realejos suffered some of the worst flooding damage on Tenerife.
Strong winds downed trees and power lines, leaving thousands without electricity. Agricultural crops sustained extensive damage, with early estimates of 50-70% losses of banana plantations. Several small towns became isolated due to impassable roads. Border closures and flight cancellations disrupted travel and commerce. Authorities evacuated over 4,000 people from hazardous areas.
Tenerife experienced the highest death toll from Delta, with 9 confirmed fatalities. Three tourists died after heavy rains triggered a rockslide over their bungalows in Los Realejos. Falling trees and walls crushed several individuals. A police officer perished conducting water rescues in Arafo. Hundreds of people needed rescue from flooded homes and vehicles.
