Met Éireann weather forecaster Joanna Donnelly has labelled the potential Storm Callum "a ferocious looking beast" as she once again warned of a storm risk toward the end of a mild and unsettled week of weather.
She said a very active weather system is expected to hit on Thursday night into Friday morning bringing with strong winds and heavy rain.
While it will be windy all week, Met Éireann is predicting a mild and almost warm week with temperatures hitting 20 degrees by Wednesday.
Callum will be the name given to the weather system if it is upgraded to storm status.
