Friday’s forecast – Strong winds and heavy rain

Good evening Western Isles on this Thursday evening we are seeing plenty of cloud with rain moving in from the West. Winds gusting 30 mph. Today’s high of 12.8C

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.

The Met Office has issued a yellow weather warning for wind for the Western Isles. The warning comes into force at 08:00 Friday morning and expires at 15:00 Friday afternoon the full warning and latest updates can be found on the Met Office website or app.

Now please note despite the warning coming into force at 08:00 we will see stronger winds across our islands before that time. I have got to the honest I am a little surprised at the warning doesn’t come into force before 08:00. Another factor of the weather which will accompany the strong winds will be heavy rain. With the likely be rains of 20 to 40 mm. Which could result in some surface flooding. The islands are also seeing spring tides at the moment so high tides could result in some road closures. I will try and update the page the best I can on this but I will be limited at times please keep an eye on the council updates for road closures. Some transport services in the Uist and Barra are not running on Friday or working on a reduced timetable and some schools are starting later in the day.

Winds this strong are nothing unusual for the island but it’s quite early in the season to see possible wind gusts in excess of 65 / 70 mph. It will be a fairly shortlived strong wind event with the worst of the strong winds being cleared away by the afternoon and it’s not in the same ballpark strong wind wise as Storm Corrie earlier this year or the 2005 or 2015 storms to calm any concerns.

Overnight and Morning – Heavy rain will sweep across the Western Isles and become persistent and slow moving. We will see winds increasing as the night goes on gusting 30 to 40 mph. By around 6 and 7 am we will see winds gusting 50 to 60 mph and thus will be the peak of the wind speeds lasting till around 10 am with winds gusting 65 to 70 mph in some spots we could see 75 mph but this is quite a low chance. The area of the very strongest winds is expected over a fairly narrow area. The heavy rain will continue for much of the morning. Winds will be from the South and shifting mid morning to come from the South West.

Afternoon and evening – The winds will ease slightly still gusting 20 to 40 mph with sunshine and showers. Some longer spells of rain at times. Winds will be from the West and South West.

Temps of 8C to 15C

Sunrise and Sunset

Stornoway – 07:27 and 19:03

South Uist – 07:30 and 19:08

Outlook

Saturday and Sunday – Sunshine and showers with brisk winds gusting 20 to 40 mph from the South West. Temps of 12C to 15C

Monday – Heavy rain and plenty of cloud with winds of 20 to 40 mph gusting to 50 mph. Temps of 11C to 14C

Tuesday – Once again looks like we could see some strong winds across the islands. Some of the models are suggesting we could see winds gusting 70 mph again with further rain. At this stage, a long way off yet first will be seeing what tomorrow brings but following the trends, I will get you a further update on this tomorrow

Have a great evening,
