Tidal and Storm Surge Forecast Service Forecast Period 10 Forecasts

Abstract: This dataset provides the forecast output csv files for the 60 forecast location points for Period 10 of the Tidal and Storm Surge Forecasting Service for the Coast of Ireland. The csv files were produced twice daily for each forecast point in the am and pm and extend for a period of 72 hours from their start point (00:00UTC or 12:00 UTC). The files contain forecasts of surge in m, total water level in m OD Malin and astronomic tide in m (relative to Chat Datum) at 15 minute intervals along with error bands. They also contain details of the forecast point location and the date and time of forecast generation. The forecast data was produced from a hydrodynamic model using best available bathymetry, output from a tidal model as a boundary conditions and operational weather forecast data as a forcing condition. Hence the forecast output will be affected by deviations between the weather forecast and actual weather. The Tidal and Storm Surge Forecasting Service was intended to provide information for Local Authorities, and other relevant stakeholders, to enable them to make informed decisions on the management of coastal flood risk. Three forecasts were produced daily, two morning forecasts looking 72 and 144 hours ahead and an evening forecast looking 72 hours ahead, with these being provided graphically on a website.

Lineage: This dataset provides the forecast output csv files for the 60 forecast location points for Period 10 of the Tidal and Storm Surge Forecasting Service for the Coast of Ireland. The csv files were produced directly from the forecast model runs and are based on the available weather forecast data at time of run. It should be noted that as each forecast is 72 hours long and new forecasts were produced every 12 hours, any single period will be covered by 6 forecast files. It would be expected that forecasts produced closer to the time of interest will be more accurate to reflect improved weather forecasts.

Purpose: The Tidal and Storm Surge Forecasting Service for the Coast of Ireland was intended to provide information for Local Authorities and other relevant stakeholders to enable them to make informed decisions on the management of coastal flood risk. Three forecasts were produced daily, two morning forecasts looking 72 and 144 hours ahead and an evening forecast looking 72 hours ahead. Forecasts were provided at 60 forecasting points, 18 National Points around the coast of Ireland and five more detailed local forecasting areas at Dundalk Bay, Wexford Harbour, Cork Harbour, Shannon Estuary and Galway Bay.
