A wind warning issued for Storm Ciara's arrival is likely to be upgraded further as the weekend progresses.
Voters heading to the polls this weekend will brave wet and blustery conditions.
Met Éireann has issued a status yellow rain warning from 12pm tomorrow until midnight on Sunday.
A status yellow wind warning is also in place between 12pm tomorrow and 3pm on Sunday.
Forecaster Gavin Gallagher said the "risk is definitely there" for the wind warning to be upgraded, particularly on Sunday.
"The rain warning will probably not go any higher than the yellow, but for the wind the potential is there for the warning to be upgraded. As with all warnings, it will be monitored.
"The risk is definitely there for Saturday but it's more likely Sunday that the yellow may be upgraded," he said.
The forecaster warned of southerly winds which are expected to reach mean speeds of 50kmh to 65kmh tomorrow before Ciara brings strong and possibly damaging gusts across Ireland on Sunday.
Meanwhile, today will be a blustery and cloudy day as temperatures of 9C to 11C will drop as low as zero, with sharp frost expected to develop in places.
Widespread heavy rain will arrive this evening.
