Rain at last

After weeks of extremely dry and dusty conditions some  significant amounts of rain fell all over La Gomera this morning. In the southwest up to 16.4 mm ( in La Dama) had fallen and most of the island had received between 7 and 14 mm by 10 am. There's a status 'yellow' weather alert for the western Canary Islands for rain up to 20 mm in one hour and for isolated thunderstorms, valid until tonight. Caution is advised on roads and hiking paths.

For the next few days some further rain showers may be expected, but with good sunny periods too.

Warning: Rainy day(s)...

...ahead, and they're welcome by local farmers who're just after planting the first spuds and other crops for you to enjoy, and by those who want to have a shower here without feeling guilty. 

BUT there's a status 'yellow' warning of heavy showers and possibly persistent rain of up to 15 mm per hour for  Wednesday 21st of  November 2018 valid for La Gomera from 9 am 'til 9 pm. More showers, some possibly heavy, are forecast for Thursday. After Tuesdays perfect day for exploring the island (images on this blog soon), please don't be deceived and avoid the spectacular valleys, cliffs, and mountains.

Thankfully it won't be very windy, but the downside of that is that the latest cold front will have more time to 'linger' and discharge precipitation to leave locally persistent rain, if and when and where. Even the odd thunderstorms cannot be ruled out. The temperature is expected to go down a  bit from tomorrow in all areas, but more markedly so in the mountains. However, still feeling warm by northern European standards and up to the low twenties ºC in the southern coastal areas.

...and don't you dare blame me for catching a nice sunny spell on a southern beach and/or a heavy shower while there. You have been warned...

For all the western Canary Islands, including all of Tenerife a 'Yellow' rainfall warning applies for Wednesday and for La Palma island they've given a 'status orange' warning.  

Summary: VERY HEAVY SHOWERS EXPECTED - DO NOT HIKE and TAKE CARE !
Tonight there's a halo around the moon, and an ol' saying goes: Ring around the moon - rain coming soon.
UPDATE: La Gomera rain alert now valid from Wednesday 1 pm 'til midnight

Relative vorticity 500mb  for Friday 12:00h UTC. Stay tuned...

A spell of windy and wet weather this Saturday

A cold front associated with a low pressure system to the north is approaching the Canary Islands and will affect us this Saturday Nov. 17th 2018. The western Canaries will be first affected and the eastern islands later. Mainly westerly winds will become strong and will gust to gale force on high ground, while rainfall amounts will vary, with some areas possibly receiving some heavier falls.

Anyway, not a day suitable for hiking in the mountains and not a day for the beach either (incl. Sunday - see previous post). Due to the expected adverse weather conditions the arts and crafts fair in La Playa (Valle Gran Rey) has been cancelled.

In La Gomera the weather should improve later Saturday  while Sunday and Monday should bring just a few well scattered light showers and longer sunny spells, best in the south. Maxima will be in the low to mid 20sºC in the southern coastal regions.

Hope on the horizon for some rain

The 'Rainbow' enhancement of today's 12 noon satellite image

While the remainder of today should be mostly sunny with few cloudy intervals, there is some hope for badly-needed rain for tomorrow, particularly during the first half of the day. A minor Atlantic depression of 1004 hPa is approaching and will soon be to the north of the Canary Islands near Madeira while filling before finally dissipating. 

There is already a lot of convective precipitation and thunderstorm activity around the low centre, but once again most of that rain is likely to pass to the north of the Canaries. There is however a good chance that La Gomera and the western Canary Islands will get some good showers and/or spells of rain, potentially even heavy ones, from late tonight until Wednesday evening.

We've also got an upper level low sitting over the same area which should aid the convective precipitation and a forming trough.  Warnings of some heavy downpours in parts of La Palma and Tenerife have been issued.

There's also the risk of some scattered thunderstorms, but the good news is that this time the winds will only be light to moderate from a mostly southerly direction. 

The weather should dry up late on Wednesday with a return to mostly sunny conditions and moderate north-easterly winds forecast for the remainder of the week.

This winter season has been much too dry in La Gomera and let's hope that this small depression will deliver some precious water before the dry weather returns.

To be on the safe side, mountain areas and ravines should be avoided tomorrow, though.

Weather gradually improving

Rough seas at La Puntilla, Valle Gran Rey, La Gomera, today.

La Gomera escaped the worst of the rain this morning as this passed just to the north of the Canary Islands. However, some very strong winds were recorded here and the weather station in the mountains at Alto Igualero recorded sustained wind speeds of well over 90 km/h with gusts of up to 144 km/h between 5am and 9am. The strong winds lead to some power outages, but no major damage was reported. However, torn branches and debris are still to be expected on roads, and as always during and for quite some time after wind and rain, rocks and soil may be dislodged and fall. Caution is advised !

The eagerly awaited abundant rainfalls failed to materialise and the accumulations during the short periods of pecipitation were pretty poor. 

Seas were, and still are, pretty rough but apparently did not disrupt ferry services. The warning for high waves will be lifted at 6 pm.

All other warnings have now ended and the weather is gradually improving with good sunny periods. There should be some more showers, possibly heavy and squally, during the remainder of Sunday, however.
A further few scattered showers could still arrive on Monday and Tuesday, mainly affecting the north of the island and the mountain areas.

Winds are forecast to become variable light to moderate on Monday and Tuesday and it should be mostly sunny generally.

Current indications are that another Atlantic depression may affect the Canaries on Wednesday with some hope of badly needed rain, but that could once again just pass us by without giving much, if any, precipitation. It is expected to dissipate anyway 😩.

Caution is advised and La Gomera's emergency plan remains activated today (Image: gomeratoday.com)

Bad weather imminent

A deceptively beautiful but disturbed looking sky at 4pm on Saturday 11-02-2017

This is just a quick update on the weather situation for La Gomera (see previous post):

Today, Saturday 11-02-2017 turned out better than expected but the forecast for tomorrow, Sunday 12-02-17, has worsened considerably and severe weather is imminent, bringing gale force winds, locally heavy downpours, isolated thunderstorms and rough seas. Appropriate weather warnings come into effect from midnight tonight and altogether 7 (seven !) weather alerts at levels from levels 'yellow' to 'orange' have been issued by the Spanish met. office for La Gomera. I won't bore you with all the details, mostly concerning time, and will just give you the synopsis:

From very early morning until late afternoon severe winds and heavy downpours can be expected, as well very rough seas. Synopsis of alerts for La Gomera :

• Westerly winds may well gust to 90 km/h in exposed areas 
• Combined swell and wind-blown waves may reach 15-18 ft on exposed coasts
• Heavy rain is expected with intensities of up to 20 mm/h with localised flooding
• The combination of rain and wind may cause landslides and rockfalls

Official warnings by Spanish met. office

The government of the Canary Islands has issued separate alerts and ...

• all public recreational areas, parks, campsites, etc., have been closed.
• it is advised to secure outdoor furniture, flower pots, etc, etc,...
• all outdoor events, sporting fixtures, outdoor markets, etc., have been cancelled.
• unnecessary travel and outdoor activity should be avoided
• extreme caution is advised generally

With a bit of luck it might not turn out to be as bad after all, but you have been warned...
Anyway, the weather should greatly improve from Sunday afternoon.

The current situation showing that the secondary low will reach 992hPa very rapidly while the main low maintains 994hPa

A windy and rainy weekend in store

Some forecasting models predict this scenario for 6am Sunday morning

SEE latest update (click this)

Wet and windy weekend weather is forecast to affect the Canaries from midnight tonight, even though the sun is shining and there are only a few clouds in Valle Gran Rey as I'm writing this.

A storm depression of 988 hPa is west off the Portuguese coast now and beginning to track south, bringing it closer to the Canary Islands. The depression is expected to be of 994 hPa tomorrow and north of these islands, before moving a bit further away to the north-northeast early on Sunday with an expected 992 hPa. Some models predict that the main depression may spawn-off a secondary but short-lived low very close and just to the north of us (see chart above), which would complicate the situation and may bring higher potential for precipitation.

What all this means is that La Gomera and the rest of the Canaries will be in for spells of rain during Saturday and on Sunday until afternoon. Some of the rain may be heavy in places and isolated thunderstorms can be expected as several frontal systems will pass through the islands. Further, strong westerly winds are expected with gale gusts and seas will be rough with a combination of 3-4 m swell and wind-blown waves.

The following status 'yellow' weather alerts have been issued for La Gomera:

Saturday, Feb. 11th 2017: 

From 00:00 am until 6 pm: Westerly winds gusting to 75 km/h or more in exposed areas.

Sunday, Feb. 12th 2017: 

From 00:00 am until 12 noon: Rain intensity up to 20mm/hour

From 3 am until 3 pm: Winds gusting to 80 km/h or more in exposed areas.
+++ A status 'orange' alert for Sunday from 4 am to 11 am: Gusts of 90+ km/h

The Canarian government has also issued weather alerts and La Gomera's government has called for extreme caution.

While the above weather forecast is not dramatic and not unusual for this time of the year, please bear in mind that the situation is still developing, possibly changing at any time, and that local phenomena and conditions can always spring a surprise.

Please do not put yourself at risk by hiking or walking in the mountains and postpone any such activity until at least a day after the weather has improved. Avoid unnecessary travel and if you must venture out, do so with extreme caution as there's bound to be debris on the roads, and falling stones and rocks are likely due to the wind and rain, especially after the long dry spell we've had. 
Late Sunday and Monday the worst will have passed but the weather will still be unsettled. Also note that warnings may be changed at short notice.
...and the just-issued OPC forecast chart for Sunday noon has confirmed a secondary low of 996hPa (below)
