Saturday’s forecast – Stormy weather

Good evening Western isles on Friday evening we are seeing rain starting to spread across the Western Isles and this will gradually become heavier as the evening progresses. Winds under 20 mph and today’s high of 11.6C

Now this will be a slightly longer than normal forecast as I guide you around the forecast for tomorrow. It’s been a while since we have had to do a storm forecast. It’s interesting to try and compare where this storm fits in comparison to other storms we have had in the past. This won’t be an event like we had with the January 2005 and 2015 big storms to make this clear. But we had a couple of stormy events in earlier this year with 60/ 70 mph winds I am expecting that to be the peak wind speeds for most areas but some parts will likely see winds speeds in excess of 70 mph.

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 yellow weather warning for wind comes into force at 20:00 Saturday evening and expires at 17:00 Sunday afternoon the latest can be found via the Met Office website or app. The Scottish Environment Protection Agency also has a flood alert in force for the Western Isles. The latest can be found via the SEPA website. It is also worth being mindful they mention causeways in the alert.

Overnight – We are going to see further heavy rain feeding across the Western Isles becoming heavy persistent and slow moving for a time. Cloud dominating. Winds for parts of Lewis and Harris but more exposed coastal fringes and for Uist and Barra gusting 20 to 40 mph. With some gusts reaching 50 mph by mid morning.

Morning – Further heavy rain and persistent rain moving across the islands but this will gradually clear away from the Islands as the morning goes on. For most, it will have cleared away by the afternoon. In its wake sunshine and showers with plenty of cloud. Winds of 20 to 40 mph gusting 50 to at times 60 mph for Uist and Barra.

Afternoon – Turning increasingly showery. These heavy possibly thundery at times. Some sunny spells. Winds of 20 to 40 mph gusting 50 to 60 mph.

Evening and overnight into Sunday. – This is the tricker part of where the strongest of the wind speeds will be. We are going to see further rain and showers. These heavy at times. This is when we are likely to see the peak of the winds. Winds of 20 to 40 mph gusting 50 to 60 mph. Along exposed coastal locations and the Western coasts, some gusts will reach 70 mph at times. Some slightly stronger gusts can’t be ruled out.

Winds will be from the West and North West. Temps of 7C to 13C but feeling much cooler in the wind chill.

Rest of Sunday – Winds and showers ease.
