Good afternoon Western isles this is an extra update looking at the weekends extremely unsettled weather. I will do a full update as normal this evening for Saturday.
A Met Office Yellow weather warning was issued for Snow and Ice for Lewis and Harris from 18:00 Saturday evening and expires at 11:00 Sunday morning. The full warning can be found via the Met office website.
Away from the Snow and Ice risk we are also going to see gales and a risk of severe gales. The winds will increase during the day on Saturday with winds gusting 40 to 50 mph reaching 60 mph by late evening. With winds in excess of 60 mph possible across the Uists and Barra.
The winds are expected to increase further as we go overnight Saturday into Sunday with winds gusting 50 to 60 mph and reaching 70 mph in some exposed coastal areas. The greatest risk being across the Uists and Barra. At this stage winds will stay below Met Office warning level for us. But i will update the page if this changes. Winds will decrease during Sunday but still gusting 40 mph.
We are also going to see some extremely heavy and persistent rain for most of the day on Saturday accompanied by strong winds this could result in some difficult conditions. As we go into Saturday evening this rain will turn increasingly to snow. Some uncertainty as to how much snow we could see. The greatest risk will be over higher ground. But we could see a covering to lower ground. These wintry showers will persist during the course of Sunday with a mixture of rain sleet and snow but will become more squally. In more sheltered areas we will see frost and ice forming.
I will keep you updated during the course of the weekend.
