I know that many of us are wary of flooding especially at this time of the year, I only live a few hundred yards from the River Severn. This Link shows you the areas that are classified as flood risk. It has a very expandable map, covering much of the world. Look and see if your house is a risk (buy sandbags, move upstairs, tether an emergency boot to roof!), or even if the neighbourhood you are thinking of moving to is at risk (move elsewhere instead?)
