Heavy rain for Tenerife over next two days

December 2010 borrasca 3

Update 7 December: Showers are forecast for Tenerife today and tomorrow, and increasing in severity enough for Aemet to raise a yellow alert for up to 15mm per hour  tomorrow in east, south and west Tenerife. The alert lasts from midnight tonight throughout the whole of Wednesday.

Update 4 December: Aemet has now issued a yellow alert for today in the municipalities of La Orotava and Vilaflor (so all the highest points of Tenerife including the crater) for winds gusting to 80 km/h. The alert starts at 6pm.

Sunday’s yellow alert for rain has also been raised to orange for maximum rainfall of 100mm in 12 hours. The orange alerts for winds gusting to 90 km/h around the entire coast, and up to 110 km/h in the municipalities of La Orotava and Vilaflor remain as previously forecast, with wind strength increasing with altitude.

Update 3 December 6pm: Aemet has raised the following alerts for Tenerife for Sunday:

Orange alert for winds gusting to 90 km/h around the entire coast, and up to 110 km/h in the municipalities of La Orotava and Vilaflor. The strength of the wind will increase relative to altitude, with gusts above even 110 km/h at the peaks. The orange alert last from midnight Saturday/Sunday until 6pm. It will reduce to a yellow alert at 6pm for winds gusting to 80 km/h.

Yellow alert for rain in the east, south and west to 15mm per hour. Alert from midnight Saturday/Sunday until 7pm. Yellow alert also for costeros from 10am Sunday to midnight Sunday/Monday.

Update 3 December: Aemet is forecasting winds of 80 km/h in El Hierro and La Palma over the weekend: that’s winds, not gusts. The new borrasca will not affect Tenerife as much as these islands to the far west of the Canaries, but the force of the wind here, especially at altitude, is expected to be “strong to very strong”, though overall it is not forecast to be as severe, nor as long lasting, as the storm which lashed the islands last weekend.

Original post 30 November: Aemet is forecasting a “new borrasca” starting on Saturday. It will bring rains, but it will not be an electrical storm such as we’ve just experienced, and most importantly, will pass quickly. It should be over by midday Sunday. Aemet says this is a different weather front to the one that is still clearing the Canaries, and they have yet to analyse it fully to decide if they need to raise any alert.
