The Big Thaw
The Big Thaw
Flooding
- As the snow melts, Scotland is likely to experience excess amounts of surface water on our roads and paths. The consequences of the thaw will depend on weather patterns - if settled conditions continue with a slight rise in daytime temperatures then any thaw will be gradual.
- River and reservoir levels are low right now so there is capacity for nature to deal with a gradual thaw. If warmer weather brings significant rain, this will add to melting snow lying on frozen ground and cause rapid run off into streams and rivers.
- Surface water flooding may occur where residual ice is blocking free drainage. Communities can play their part by clearing drains in their streets and gardens.
- SEPA monitors rainfall and river levels around the clock, using this information to update the Floodline service. This information can be accessed through SEPA's website at http://www.sepa.org.uk/ and also via FLOODLINE - 0845 988 1188.
Advice to householders
- When moving snow and ice from your path, put it kerbside being careful not to block drains in gutters.
- Many households have been using alternatives to grit, including salt, cat litter and sand. This could lead to blockages in the drainage system leading to flooding problems. The best advice is to use it sparingly, try to sweep up any excess and clear up any residues left after the thaw.
- Be aware that snow could fall from roofs suddenly. Be prepared and predict where it might fall and don't park your car, bikes or garden furniture in its landing path.
- Pipes - if you experience a burst pipe, turn off the stop valve immediately, open all cold taps to drain the system, but don't turn on the hot taps - your hot water cylinder may collapse if the pipes leading to it are frozen. www.scottishwater.co.uk
- Call a licensed plumber if you are in any doubt about what to do.
- Continue to wrap up warm, temperatures may rise through the day but the wind chill is deceptive and temperatures are still likely to be very low at night. It's still only mid January, the severe weather could return so continue to be vigilant.
- Whilst roads and paths may be more accessible for most, vulnerable groups may still be wary of venturing outside, especially as temperatures remain low.
- Scots have showed tremendous community spirit through the recent extreme weather; please continue to do your bit for any older or less able people in your community.
Advice to drivers:
- When the road's wet, it can take up to twice as long to stop so slow down.
- If your vehicle loses its grip, or "aquaplanes", on surface water take your foot off the accelerator to slow down. Don't brake or steer suddenly because you have no control of the steering or brakes.
- If you can avoid it, it's best not to drive through lying surface water as you might flood your engine. The deepest water is usually nearest the kerb. Beware of hidden and damaging pot holes or debris that could be lurking in puddles of surface water.
- Drivers should listen out for weather warnings and be prepared to change or delay journeys depending on advice being given.
- Always check your route before you set out. Check the real-time traffic information provided on our routes at http://www.trafficscotland.org/
- If you do have to drive through flooded roads, use first gear. Move forward immediately to avoid stalling the engine. Keep your revs high and depress your clutch when you need to.
- Test your brakes after driving through water. If they work then you can drive on at your usual speed providing it's safe to do so.
