Tropical Storm Delta (2005) Tenerife

Introduction to Tenerife

Tenerife is the largest and most populous island of the Canary Islands, an Spanish archipelago located in the Atlantic Ocean off the coast of Western Africa. With an area of 2,034 square km and a population of around 900,000 inhabitants, Tenerife stands out for its vibrant tourism industry, stunning volcanic landscapes, and rich biodiversity.

The island’s unique geography and climate have played a major role in its history and development. Tenerife features Spain’s tallest mountain, Mount Teide, a 3,718 meter active volcano that dominates the center of the island. 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)
