The Road Safety Authority advised people to slow down when driving as visibility was likely to be reduced and stopping distances increased during the storm.
Met Éireann said Storm Deirdre was likely to "move quickly across the country this afternoon and evening and will move through the Irish Sea early tonight. It will give some squally, damaging winds in all areas for a short period of time".
The forecaster said the winds would peak in the afternoon in Munster and Connacht and in Leinster and Ulster in the early evening.
A status yellow rainfall warning was issued with up to 5cm of rain forecast while a separate status yellow wind warning is in place for Dublin, Louth, Wexford, Wicklow, Meath, Donegal, Cork and Waterford.

With just 11 days and two weekends to go until Christmas, ISME, the Irish small and medium enterprise association encouraged consumers not to be put off by Storm Deirdre and to consider spending their money in the businesses in their communities.
“Undoubtedly, this weekend’s weather will impact shopping numbers on what is one of the busiest shopping weekends of the calendar year,” said ISME chief executive Neil McDonnell.
He appealed to Irish consumers “to continue to support local producers, manufacturers, and retailers by shopping and dining local”.
Mr McDonnell pointed out that every €10 spent locally on Irish products generated more than €40 of benefit to the local community in employment terms and he stressed the importance of the retail sector local economies across the State.
