Storm Dennis - flooding outlook Monday 17 February

  17 February 2020

Mark McLaughlin, SEPA's Duty Flood Manager, said:

"While Storm Dennis is now leaving Scotland, there will still be frequent showers and strong winds today.

"River levels are now falling across Scotland but they remain high and catchments are wet.

"Heavy, and in some places prolonged, showers are forecast throughout Monday and Tuesday. These could result in short-lived increases to river levels causing localised flooding. The heaviest rain is expected from Sutherland down to Tayside and Central. 

"Surface water flooding is also possible where showers fall in areas that are already wet from the weekend.

"Spray and wave overtopping is likely at high tide along the west coast, particularly Ayrshire, and around Orkney and Shetland.

Many areas are already saturated due to wet weather earlier this week and will react quickly to the most intense rainfall. Report-A-Flood enables anyone to share information on current flooding issues, helping to reduce the disruption which flooding can cause. You can report flooding at

What are Flood Alerts and Flood Warnings?

We use forecast weather information provided by the Met Office combined with our own observation of rainfall and river levels and advanced hydrological modelling to provide advance warning of flooding.

Regional Flood Alerts are early advice that flooding is possible across a wider geographical area.

The purpose of the Alerts is to make people aware of the risk of flooding and be prepared. We normally issue them 12 to 24 hours in advance of the possibility of flooding.

Flood Warnings are more locally specific and are issued for areas where we have gauges on rivers to measure the exact river height. They are issued at shorter notice when we are more certain that a specific area will be affected.

What should I do?

People should be prepared for the eventuality that flooding will affect them:

  • On the road or on public transport we can expect difficult conditions. Drive with care, and do not travel through deep fast flowing water.
  • If you are walking along rivers, be also extra careful of wet footpaths and possibly small watercourses in spate.
  • If your property is vulnerable you should be ready to take action, assess your risk, if required move your car to higher ground, put in place flood guards if you have such equipment, and protect valuables.
