Pascal Lardet, Flood Unit Manager for the Scottish Environment Protection Agency said:
At present four flood alerts are currently in place for Central, Tayside, Fife and the Scottish Borders, reflecting a risk of flooding for the western parts of these regions during Friday and Saturday.
"Rain, accompanied by strong to gale force southerly winds, is expected during Friday and will be heaviest over North Argyll, Lochaber, the Southern Highlands and Northwest. In these regions, the transport network may be affected by surface water and drivers should remain vigilant.
"The River Earn (Tayside), River Teith (Central), head waters of the Tweed catchment (Scottish Borders), and neighbouring watercourses, may also be affected by the heavy rain.
"In the North West and Western Isles, strong winds may also cause exposed areas of west facing coasts to be impacted by spray and overtopping from large waves during Friday and Saturday.
"Businesses and members of the public can access the latest flood updates for their area, and sign up to Floodline, our direct warning service, via our website www.sepa.org.uk, or by calling 0845 988 1188."
