Update 16 August: As though we didn’t know it, there is now official confirmation that the rains and storms forecast for yesterday and today did not affect Tenerife, nor any other of the Canaries. It seems that the rain fell between the African coast and Fuerteventura, short of the islands themselves, and that the weather front then moved northwards. Aemet says that normal weather service is now about to resume. C24H
