Storm begins to clear Canaries after a wild night

Storm begins to clear Canaries after a wild night

rain and winds alert nov 2010 6

Update 30 November: Well, I’ve never experienced lightning from within a thunderstorm before. It was otherworldly … at times it felt nextworldly! We are at the bottom of the altitude for the strongest winds, and they were bad, and fully worthy of their red alert, but that’s all. Throughout Tenerife, some hoardings are down, a crane or two, and worst of all, seven or eight pylons on the east coast, meaning that about 30,000 or so were without electricity (and I understand one mobile mast came down too so some didn’t have mobile phone coverage). Endesa says that of those who lost their power yesterday, all but 6,000 are reconnected: those still affected are in the municipalities of Los Realejos, La Guancha, San Juan de la Rambla and Icod de los Vinos.

But not to overplay it, no-one died, one person is said to be injured in the north from a flying gate. This was not Delta by a mile. Delta had winds of 110 km/h … that’s winds, not gusts! At one point Delta was officially a hurricane, but the wind speed didn’t last long enough for the storm to be reclassified up from a tropical storm. And let’s not forget the deaths in 2002, from floods. The rain I saw last night was up there with the 2002 storm, but no-one died this time, thank god.

It was a bit hairy, but what an experience. This is what the lightning looked like in graphic form:

This is what the radar shows now. It’s a nice sight!

As of now, the picture at the top shows the alert status: Tenerife has a yellow alert in the north, for rain up to 15mm per hour, and another for wild seas. The forecast is for continued showers and squalls, sometimes heavy, in the north this afternoon, with gusty wind from the southwest particularly at altitude, turning around midday to come from the northwest, and lessening in the process. To all intents and purposes, it’s over.

Update 29 November 4pm: The worst is over, and Aemet has reduced the alert from red to orange and yellow as per the forecast below:

Today:

  • Rain:  Orange alert for 30mm rain per hour in the east, south and west, with thunder and lightning. Yellow alert for 15 km/h rain per hour in the north and at altitude.
  • Winds: Orange alert for gusts to 90 km/h rising to gusts of 120 m/h at altitude.
  • Yellow alert also for “costeros”.

Tomorrow Tuesday:

The storm is passing, and there is just a yellow alert, and only for the north coast and altitude for rain up to 15mm per hour. No wind alert.

Update 29 November: It was not as bad a night as had been feared, with La Palma the worst affected, but even there not as awful as expected for a red alert. At 1km altitude, we had a bit of a breeze and steady rain, no more.

From the press this morning:

  • Schools throughout Canaries closed today, but probably will be open again tomorrow, announcement later. Government telling people to go to work though, so not saying stay at home any more.
  • Emergency plan alert that is routinely put in place is now likely to be reduced through the morning.
  • 150 km gusts registered in Izaña (122 km/h in La Palma). Hardly been noticed in Gran Canaria, which was included in the red alert.
  • Binter reports some problems with flights in La Palma, El Hierro and La Gomera airports. No problems reported in Tenerife airports.
  • Thunderstorms with heavy rain expected today around midday, especially in the south and west. High winds expected at altitude increasing in severity to high altitude.

Updated 5pm: As part of the official announcements over school closures tomorrow, the Government minister for Presidencia, Justicia y Seguridad, José Miguel Ruano, advised the public not to leave the house unless the journey was unavoidable, in which case to take extreme precautions. He also advised people to ensure that doors and windows were closed, and at all costs to keep away from the coast to avoid being washed away by the expected wild seas.

Perhaps to alleviate alarm caused by discussions in some of the local press which have been talking the storm up (in one instance to hurricane status), Sr Ruano stressed that for all the caution required, this was not a tropical storm and that it would not recreate the conditions of Delta, which lashed the islands in 2005.

Updated 28 November 11am: Aemet has issued a red alert for tomorrow for gales for the whole of Tenerife, with gusts of up to 130 km/h expected throughout the island, rising to 170 km/h at altitude.  Aemet

Updated 28 November 10am: Aemet’s latest forecast for today is mainly unchanged from yesterday’s, with winds gusting to 70 km/h, up to 60mm of rain in 12 hours, and “costeros”, i.e. wild seas. The only change is for slightly stronger gusts of winds at altitude, where gusts of up to 100 km/h expected.

Monday’s forecast remains the same, with thunder storms, “costeros”, rain of up to 60mm in 12 hours, and winds gusting from between 90 to 120 km/h depending on altitude.

Updated 27 November: The first front has now passed, and the second one is due to arrive tomorrow. Aemet’s current forecast is for tomorrow and Monday:

Tomorrow Sunday: as per its original forecast, yellow alert for winds gusting to 70 km/h except at altitude where gusts up to 90 km/h are expected. Rain, as before, expected up to 60mm in 12 hours. “Costeros”, i.e. wild seas.

Monday: yellow alerts for rain up to 60mm in 12 hours, costeros, and “tormentas”, i.e. thunder storms. Orange alert for winds gusting from 90 km/h around the coast to a maximum of 120 km/h at extreme altitude. The wind speed, and therefore gusts, will increase in line with altitude. Aemet

Updated 26 November: Rumours have been circulating that we’re about to get hit on Sunday and Monday by an “historic” storm, which has even been given the name Andres. There is no mention of  any “tropical storm”, however, let alone one called Andres, on the official Met Office website for Sunday, so these rumours are almost certainly based in confusion or scaremongering. From what I can see, “Andres” was a major tropical storm in June 2009, and a quick glance at THIS website could make someone think that it was happening now, but the map below the date of the actual story clearly shows the tropical storm referred to was a Pacific storm last year.

Aemet’s forecast for the next few days is for more of the same as we had yesterday, though with heavier rain and higher winds. The yellow alerts already set in place remain so. For Sunday in Tenerife, Aemet’s yellow alert is for wind gusting to a maximum of 70 km/h, but up to 90 km/h at altitude (for which the alert is orange), and for rain everywhere on the island up to a 12 hour maximum of 60mm. Aemet also has a yellow alert for Sunday for what are called “Costeros”, or coastal phenomena. Essentially, it’s blustery weather on the coast with wild seas. HERE is the Aemet link to confirm for yourselves.

Original post 24 November: Aemet is forecasting heavy rain and high winds for Tenerife over the next few days. The current forecast lasts until Tuesday, and the met office has raised weather alerts for up to 15 mm of rain per hour and winds gusting up to 90 km/h. The yellow alert will be in place from midday tomorrow, rising to orange on Friday.
