Open Data - Flood Risk Forecast API

API change history

The flood risk forecast is produced by the Flood Forecasting Centre (FFC) on a daily basis. It is issued more frequently when serious flooding is forecast. It provides the indication of the potential for flooding for five days: the day on which it is issued and the subsequent four days ahead.

The forecast highlights flood risk on a county by county basis and includes a short commentary on the situation. It covers flooding from rivers, the sea, surface water and groundwater for England and Wales.

Areas at risk of flooding

Areas at risk of Flooding are available as a single JSON data structure which includes all counties at a risk level of Low, Medium and High.

Counties with a risk level of Very low are NOT included in this operation.

Property Name Property Description Type
Day_en The date of the area is at risk in English string
LocationCounty_en Location of county affected within England and Wales in English string
Region_en The region affected by the forecast risk in English string
RiskLevelName_en The Level of risk for this county in English string
Day_cy The date of the area is at risk in Welsh string
LocationCounty_cy Location of county affected within England and Wales in Welsh string
Region_cy The region affected by the forecast risk in Welsh string
RiskLevelName_cy The Level of risk for this county in Welsh string
