75mm OF RAINFALL OVERNIGHT AT REST AND BE THANKFUL AS REGIONAL FLOOD ALERTS REMAIN IN FORCE FOR NORTH WEST SCOTLAND

75mm of rain fell in a 24 hour period at the Rest and Be Thankful,  Argyll as Scotland faced a weekend of wet weather.  On Saturday and overnight, Scotland’s flood forecasting and warning service had 10 Regional Flood Alerts and 7 Local Flood Warnings in force.  In total, the Scottish Environment Protection Agency said that between 70mm – 80mm fell across the day yesterday and overnight, with further rain and flooding impacts predicted across the North West of Sunday.

Mark Franklin, SEPA’s Duty Flood Manager, said:

“Yet again we’ve seen Scotland battered by another weekend of wet weather, with flooding impacts across West, Central, North and Southern Scotland.  At the Rest and Be Thankful in Argyll, the subject of a second landslip in a matter of weeks, we saw 75mm of rain in a 24 hour period and across the country we saw rainfall of between 70-80mm. 

“Our 24/7 flood forecasting and warning centre saw people responding well to our 10 Regional Flood Alerts and 7 Local Flood Warnings and we want to thank those who signed-up overnight for our free Floodline service.

“Whilst Sunday see’s an improving picture for Central and Southern Scotland, we’ll see continued heavy rainfall across the day for the North West.  This is likely to result in further localised flooding of land and roads, as well as some transport disruption before improving on Monday.  People living, working and travelling in these areas are advised to ensure they have signed up to Floodline and are prepared to take action to protect property. Advice on what you can do to prepare can be found at floodlinescotland.org.uk.”

Rainfall Data:

Staying informed

  • All SEPA’s Alerts and Warnings are available on our website at floodline.sepa.org.uk/floodupdates/
  • Floodline is always the most up-to-date information – with any new flood updates available as soon as they are issued.
  • You can also sign up to receive these messages to your phone, for free. You can register online at floodline.sepa.org.uk/floodingsignup/

Be prepared and stay safe

  • Check Floodline - visit sepa.org.uk/floodupdates
  • Don’t walk through flood water – 15cm of fast flowing water could be enough to knock you off your feet and hazards can be hidden under the water.
  • On the road or on public transport we can expect difficult conditions.
  • Drive with care, and do not travel through deep fast flowing water. It only takes 30cm of fast flowing water to move an average family sized car.
  • If you are walking beside rivers be extra careful of wet footpaths and possibly small watercourses in spate.

What’s the difference between a Flood Alert and a Flood Warning?

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.
