Met Eireann is warning of downpours which will lead to 'dangerous driving conditions.
The stormy conditions are expected to impact Leinster and east Munster the most.
Meteorologist Emer Flood says it will remain unsettled for the rest of the week due to a much fresher air mass.
"People can expect it feeling a lot fresher and much cooler particularly on Wednesday when it could be widespread again."
