Sunday’s forecast – Storm Corrie

This is going to be a long update so bear with us but I want to give you as much information as possible and it has been a long time since an Amber warning was issued for the Western Isles. The last one was for Storm Caroline in 2017. The 2015 storm that hit in January was an Amber storm but I thought should have been a red warning. This I don’t expect to be as powerful as that.

So the Met Office Amber warning comes into force at 17:00 Sunday evening and expires at 06:00 Monday morning. A yellow warning comes into force two hours earlier at 15:00 and expires six hours later at 18:00. The full warning and latest updates can be found via the Met Office website or app.

Please do NOT use Western Isles Weather for the protection of life and property please follow local and national government issued warnings and advice. Please have more than one source for weather information in extreme weather, Such as the Met office and follow any advice and instructions from emergency responders.

Now on this Saturday evening winds have abated we are seeing heavy and squally showers moving across the islands. Plenty of cloud but decent amounts of clear spells. Winds gusting 30 mph and today’s high of 11.1C

Overnight – Clear skies and cloud. A few scattered showers but most places staying dry with a touch of frost and ice in places. Winds of 10 to 30 mph.

Morning – Sunshine and cloud first thing but rain and cloud will move across the islands and this will become heavy and persistent. Winds will slowly start to increase. gusting 20 to 40 mph.

Afternoon and evening – This is the challenging part. Depending on the exact track of the low will determine how strong the winds get. The strongest winds will occur when the winds go from the South West to the North West. At this stage, the strongest winds look set to be from Harris, North and South Uist, Benbecula, Eriskay, Bernery, Barra and Vatersay. But deviations further North will bring stronger winds further North. Do not underestimate this system. It will not be the worst we have ever seen but these winds will be powerful. I would rather an abundance of caution and for it not to be as bad people expected. So winds will strethen gusting 50 to 60 mph widely. Stronger winds for the above Southern locations gusting 70 to 80 mph. In some exposed coastal spots reaching 90 mph. Easing down a little late evening to gust 60 mph widely. We will see heavy and persistant slow moving rain push across the islands. Upon the low pressure clearing away and the main band of heavy easing we will left with a sqaully showery regime in its wake. This heavy and wintry at times. Possibly thundery.

Winds will be from the Souh and South West shifting North West. Temps of 2C to 10C but feeling colder in the wind chill.
