A Met Éireann yellow rainfall warning for counties in the west and southwest is currently in effect.
Counties in these areas, particularly Galway, Mayo, Clare and Kerry will see thundery rain and possible rainfall levels of 30mm-50mm. The warning is in place from 9pm Thursday to 9pm Friday.
The eastern half of the country is to remain largely dry with sunny spells during the day but winds are set to be brisk.
Later in the afternoon, scattered heavy and possibly thundery showers will gradually head eastwards, with highest temperatures between 14-18 degrees.
Heavy rain was predicted to move up across the country with the risk of thunder and localised flooding. Highest temperatures will be between 8-12 degrees.
This warning follows a period of heavy rainfall and thunderstorms which left around 10,000 people across the country out of power. In particular, areas such as Athenry and Tuam in Co Galway were badly affected.
