AN INTERACTIVE map has revealed what parts of Powys and surrounding areas could be underwater in just seven years.
Created by Climate Central, the interactive map shows areas threatened by sea level rise and coastal flooding by 2030. It combines the most advanced global model of coastal elevations with the latest projections for future flood levels.
Climate Central’s sea level rise and coastal flood maps are based on peer-reviewed science in leading journals.
As these maps incorporate big datasets, which always include some error, these maps should be regarded as screening tools to identify places that may require deeper investigation of risk [areas that may be more at risk of sea levels rising].

The red marked areas of the map are projected to be lost to the sea by 2030.
Areas lower than the selected water level and with an unobstructed path to the ocean are shaded red.
The maps are not based on physical storm and flood simulations and do not take into account factors such as erosion, future changes in the frequency or intensity of storms, inland flooding, or contributions from rainfall or rivers.
Powys does not escape being submerged despite being inland with Machynlleth and the surrounding area lost to the sea as far as Dyfi Bridge.
Further west the villages of Pennal, Furnace and Eglwys Fach would also be under water, based on the forecast map, as well as the current site of Dyfi Osprey Project.
Both sides of the Dyfi estuary are expected to be impacted with Aberdovey and Towyn projected to be submerged while the popular coastal town of Barmouth would also be lost by the rising sea, according to the maps.
Further south a vast swathe of northern Ceredigion would be swamped by the Irish Sea as far south as Aberystwyth, which the map makers think would be submerged along with Aberaeron.
