Flooding outlook - Wednesday 27 and Thursday 28 October

  27 October 2021

Pascal Lardet, Flood Duty Manager for the Scottish Environment Protection Agency, said: 

“Heavy and persistent rain is forecast across southern Scotland on Wednesday and overnight into Thursday, with the Met Office indicating totals of 60mm of rainfall widely, and possibly 100mm on higher grounds over a 24-hour period.

“River and surface water flooding is likely, particularly in eastern Dumfries & Galloway and western Scottish Borders. There could be localised flooding to low-lying land and roads, disruption to travel and flooding in parts of communities. We are monitoring the situation closely with partners in areas such as Hawick, Newcastleton and Langholm. Flooding could also affect stretches of the M74 across to England overnight.

“Regional Flood Alerts are in place, and Local Flood Warnings will be issued where necessary. People living and working in affected areas are advised to plan their essential journeys and consider the steps they need to take now to be prepared.

“Surface water flooding may occur in areas not normally prone to flooding and impacts from flooding from small and minor watercourses may also occur, so remember that conditions can change rapidly and water levels may rise quickly with little warning.

“Further rain is currently forecast for the end of the week and into the weekend. SEPA is working 24/7 to monitor rainfall and river levels and is in close contact with the Met Office and other partners to review the forecasts, which are combined with local expertise from all regions of Scotland to understand and present the flooding risk. The most up-to-date information is always available on our website.”

Be prepared and stay safe 

  • Check Floodline – visit www.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.
  • 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’re walking beside rivers be extra careful of wet footpaths and possibly small watercourses in spate.
  • Consider deploying flooding protection products if required.

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.
