Flooding can cause enormous damage. If you know beforehand that there will be a flood, you can prepare for it and limit the consequences.
In Norway, the weather is monitored continuously, and we tend to get advance warning of major floods, either through weather warnings or special flood warnings. This allows individuals and the authorities to prepare as well as possible.
If you keep any moveable objects like caravans, boats or other such items in the garden, get them out of harm’s way or secure them. These items tend to be valuable. They can also cause huge damage to bridges and buildings if they are swept downstream by the flood.
Think ‘prevention’ and make good use of the time you have before the flood arrives. To limit the damage to your property, you should pay particular attention to ensuring that your gutters are clear and that drainpipes and drains are not blocked by leaves or twigs. Also get valuable items out of the cellar. Check that windows and doors are properly closed, particularly in the cellar.
