Update 8 October: Although we’ve clearly seen some effect from being skirted by this borrasca, it is now very unlikely to have any further effect on us at all. Despite being called “a hurricane” it is actually “Tropical Storm Leslie”, and it’s heading away from us after coming towards us for a few days. This is Aemet’s latest projection from the Hurricane Centre of its path, to the north and east and still quite a way from Tenerife, and becoming more distant as the hours pass.

Update 7 October: I’m not sure that the forecast is really any clearer for Tenerife but the borrasca identified as approaching from the west has now seen La Palma put on yellow alert from this afternoon for rains. How near us this will get is still unclear but it seems very likely that there will be some evidence of it in the build up of clouds, winds and showers over the next few days.

Original post 5 October: It’s not “winter”, of course, and in fact we’re only just into Autumn, but the first real weather system of autumn/winter 2018-19 is almost with us. Already we can see the build of up clouds brought by a borrasca (atmospheric depression) kept at bay for some weeks to the west of the Canaries by the “calmas”, the period of equilibrium between the two main weather systems we’re subject to – the alisios (trade winds) from the Atlantic and hot air from Africa. Now, though, the borrasca is approaching us, and could bring rain to some parts of the western islands and winds which will be felt at altitude especially. The forecast for the next several days is still being developed and it is unlikely that we’re going to get a “storm” but certainly we can expect temperatures to drop somewhat, some blustery winds, and possibly some rain at times in some places: the following video from MeteoLaMatanza shows the graphics of the approach. Winter’s coming …
