Chart shows the probability of forecast precipitation in 24-hour intervals exceeding accumulations of 1mm, 5mm, 10mm, 20mm, 30mm, 40mm, 50mm and 80mm.
If none of the legend colours appear on a particular map, this indicates that the probability of exceeding that threshold is less than 10%.
The probabilities are calculated using data from Met Éireann’s high-resolution Ensemble Prediction System, IREPS.
The colour coded thresholds relate to Met Éireann’s colour coded warning levels. However, warnings are not exclusively determined by threshold exceedances as forecasters take potential impacts into account also.
