Pascal Lardet, from SEPA's Flood Unit, said:
The Met Office has forecast that rain will push in from the southwest tonight and will be heaviest in northwest Scotland. The weather remains unsettled for the week ahead, with a risk of flooding affecting most parts of Scotland from Monday.
"On Monday, due to a combination of rainfall and snowmelt there is a risk of river and surface water flooding in Caithness and Sutherland, Easter Ross and Great Glen, Wester Ross, Skye and Lochaber, Argyll and Bute, Central, West Central Scotland, Ayrshire and Arran, Tayside, and Findhorn, Nairn, Moray and Speyside.
"This may result in a risk of flooding to isolated properties, low lying land and roads and cause travel disruption.
"There is also a risk of localised coastal impacts during Monday in the Western Isles due to spray and overtopping.
“Storm force winds are expected across Scotland as Storm Henry moves in from Monday afternoon, with more rainfall affecting the North West of Scotland. We are continuing to monitor the situation and the latest updates will be available on the live flood updates page of the SEPA website. We also encourage people to sign up for free flood messages direct to their phone by calling Floodline on 0345 988 1188 or via our website.
"Members of the public can also use the Report–a-Flood tool to inform us of flooding incidents. SEPA will publish these reports online to increase awareness of local flood impacts and help keep communities informed of the areas most affected. Please note that Report-a-Flood is purely for information sharing and cannot be used to report problems, ask questions or report emergencies. Emergency situations should always be reported to the emergency services.”
