"Canaries will feel tail effects of Tropical Storm Nadine from Friday
19 September 2012
Aemet is forecasting a possible kick for us in the tail of Tropical Storm Nadine, which is arriving in the Azores this evening, and could bring at last, some rain to the Canaries on Monday. Chief of Predicción y Vigilancia de la Aemet en Canarias, Jesús Agüera, said today that the storm should cause a large swell in the sea from Friday, particularly noticeable in La Palma and La Gomera. There should also be moderate winds, strong at altitude, but nothing, he said, that will warrant the raising of any alert. Rain, if it comes, will not be 'intense'."
There are other reports on Tripadviser, etc, so it looks as if it is going to happen. Batten down the hatches!
