A status yellow rainfall warning has been issued for four counties along the east coast.
Met Eireann says persistent rainfall can be expected in Dublin, Louth, Meath and Wicklow, with accumulations of between 25 to 35 millimetres.
The warning is in effect from midday, until the same time tomorrow.
Status yellow is one of the three categories of alert issued by Met Éireann and it is to notify those who are at risk because of their location and/or activity, and to allow them to take preventative action. It is the lowest level of weather warning issued by the forecaster.
Yellow-level weather alerts are for weather conditions that do not pose an immediate threat to the general population, but only to those exposed to risk by nature of their location or activity.
A small craft warning is also in place and Met Éireann said east to northeast winds would reach force 6 on all Irish coasts overnight and during Tuesday.
