Scottish Hydro Electric Power Distribution (SHEPD) is now operating at red alert as Storm Henry threatens to cause disruption across much of Scotland.
With gale force winds of more than 90 mph expected across the Western Isles, Skye and north west Highlands, the hydro has deployed engineering and technical teams to areas most likely to be affected by the extreme weather.
As well as strong winds, high sea swells are expected to cause flooding along coastal roads in these areas.
As a precautionary measure, SHEPD has moved resources and engineers to islands that could be cut off if ferry sailings are cancelled.
Additional advisors are on duty in its customer services centre, and welfare teams have been contacting vulnerable customers to see if they need extra assistance if there were to be a power cut.
People who need assistance or experience a powercut, can call on 0800 300999.
