Protect yourself

  • Keep children and vulnerable people out of floodwater.
  • Avoid walking through flood water, you may not be able to see through flood water, to see kerbs and there are likely to be other underwater dangers such as open manholes.
  • Avoid driving through flood water, only a small amount can float a car and could be dangerous to you. If you drive please do so slowly as bow waves caused can result in water entering properties.
  • Further information is available on the AA website.
  • Don't walk on sea defences or riverbanks.
  • Take care or avoid crossing bridges when water levels are high.
  • Take care crossing culverts as they are dangerous when flooded.
