Marc Becker, Duty Flooding Manager for SEPA, said:
"Heavy and persistent rain falling on saturated ground is expected to cause isolated flooding of low-lying land and roads across western Scotland this evening and into tomorrow.
"The areas expected to see the most impacts are Inverclyde, Renfrewshire and North Ayrshire, particularly communities around the Black Cart Water and River Gryffe where property flooding and travel disruption are possible. The latest forecasts and model runs are showing similar levels to those experienced during Storm Desmond in December 2015.
"These rivers and other, smaller watercourses in the area, do not have flood warning schemes. Therefore the Flood Alerts out for these areas contain the relevant information. You should take action now to protect yourself and your property if you are in an area that is likely to be affected.
"Other areas likely to see difficult driving conditions and ponding of water in known trouble spots are West Central Scotland, Skye and Lochaber, Argyll and western parts of Central and Tayside. Wind debris, such as fallen leaves, may increase this risk by blocking drains.
"High tides will peak over the next few days, around the whole Scottish coastline, increasing the possibility of some isolated minor flooding to low-lying land and roads. Northern and western coastal areas exposed to the strong west or south-westerly winds may see instances of spray and wave overtopping at high tide, but these are not currently expected to cause any notable flooding issues.
"As always, we continue to work closely with our partners in the Met Office, the Scottish Flood Forecasting Service and local authorities to ensure they have the latest updates and would encourage members of the public to remain vigilant.
"Live, real-time flood updates are available on the SEPA website or for specific notifications for your area, please sign up to Floodline on 0345 988 1188. People can also report and check flooding impacts in their area using Report-a-Flood.\"
