Flooding in La Laguna in 1977 |
Between 10 and 13 April 1977 there was an intense rainy episode, lasting several days in the Canary Islands that left precipitation of more than 350 l / m2 in the south west and of more than 220 l / m2 in the south east of Tenerife.
San Cristóbal de La Laguna was partially incommunicado for several days due to this Easter flooding. The powerful SW storm of Holy Week of 1977 is one of the most important storms of the 20th century in the Canary Islands. It affected the entire western province and Gran Canaria, but was especially virulent in Tenerife, with 358.9 mm in Vilaflor on 11 April; 260.3mm at Los Rodeos on 10 April.
In El Escobonal (Güímar), also in Tenerife, more than 400 mm of rain fell during just this storm, when its annual average is around 380 mm. It caught everyone off guard with their mind still on the recent Los Rodeos accident.
