Strong winds of up to 85mph are expected to blast the north west of the country, according to forecasters.
Wind speeds on the west coast from northern Argyll to Cape Wrath are predicted to hit between 70 and 80mph leading to the risk of structural damage and challenging driving conditions.
The Western Isles are forecast to be the worst hit and have been issued an amber "be prepared" warning for wind by the Met Office with gusts peaking as high as 85mph before it slowly eases off.
Poor conditions are also expected in the east where SEPA has seven flood warnings in place for Tayside as rain continues to fall on the region. There are no warnings in place in the north east which was previously badly flooded with around 100 residents from Stonehaven evacuated from their homes.
Matt Dobson, senior forecaster with MeteoGroup, the weather division of the Press Association, said: "In the Western Isles of Scotland and the west coast of Scotland from northern Argyll up to Cape Wrath and across the north coast gusts of wind will be in the region of 70 to 80mph until about 3am then it will gradually ease down.
"In the Outer Hebrides gusts may reach up to 85mph.
"Even inland to Argyll and Glasgow, Loch Lommond and Fort William there could be gusts up to 60mph. There could be difficult driving conditions with the odd tree or bransh being blown down.
"The really severe conditions are likely to cause structural damage where winds are over 70mph and particularly in the lesser populated areas of the far north."
A spokesman for the Northern Constabulary said: "There are warnings of localised flooding along with surface waters on roads with a strong possibility of disruption to public transport.
"The public in the Western Isles are also advised of the potential for causeways to close for indeterminate periods this evening and to check partner agency websites and listen to radio reports for further updates."
