Western Isles election officials are monitoring weather forecasts in case gale force winds hold up vote counting tonight.
Ballot boxes are due to be transported by boat and chartered plane when voting in the Scottish parliamentary elections ends at 10pm.
Counting takes place in the Lewis Sports Centre with hopes to declare the result before 2am.
The Met Office said: “Low pressure over the northeastern Atlantic will bring strong to gale force winds for a time across northern areas, and across northwestern Scotland today in particular.”
High winds resulted in the Harris ferry being stormbound in harbour.
A spokesman for Malcom Burr, returning officer for Na h-Eileanan an Iar, said: “We are keeping an eye on the weather and hope things go-ahead as planned. There is a contingency plan in place.”
Ballot boxes from the two polling stations in Barra are due to be transported across the Sound of Barra to Eriskay.
They will be driven to Balivanich Airport where the 11 boxes from between Eriskay and Berneray will be loaded onto a hire aircraft for the flight to Stornoway.
In case of adverse weather or plane breakdown, a fast boat is on stand-by to transfer ballot boxes to Harris.
