 "notes": [
  "High risk is a chance of flooding greater than 1 in 30 each year; medium between 1 in 30 and 1 in 100 from rivers and 1 in 200 from the sea; low between that and 1 in 1,000.",
  "Natural Resources Wales's figures carry no statistical designation, and it replaces the dataset rather than revising it. It also gives a forecast for 2120, which the hub leaves out, and figures without defences. England's properties at flood risk are the Environment Agency's, on their own page."
