The Comhairle and the Counting Officer for the Western Isles, Malcolm Burr, are continuing to monitor the situation as fog threatens to delay the Scottish independence referendum count in Stornoway tonight.
All ballot papers from the Western Isles need to be transported to Stornoway to be counted at Ionad Spòrs Leòdhais.
The plan, after the polling stations close at 10pm tonight, is for ballot boxes from Barra to be taken by sea to Eriskay then by road to Balivanich where they will be loaded into a fixed wing aircraft alongside the Uist votes before being flown to Stornoway.
It that goes ahead the result from the Western Isles, which will be added to the national total, is expected to be declared at around 2am.
However, if foggy conditions persist the vote would be delayed by around three hours, until around 5am, as ballot boxed would have to be transported by sea and road.
A Comhairle spokesman said: “Plan B is ready if necessary. We are continuing to monitor the situation and will take decisions later in the day.”
