Ireland will be lashed by heavy rain and thundery showers as weather chiefs predict a washout weekend.
The worst hit areas will be in the south and east of the country, as a band of rain moves across Ireland on Saturday.
Experts have warned that Munster and south Leinster are at the most risk of being hit by flooding after the downpours.
There will also be some heavy showers today with the strongest rainfall in the west, leading to a possibility of "localised flooding".
A Met Eireann forecaster said: "Sunny spells and scattered showers today. Some of the showers will be heavy and with an increasing risk of thunderstorms leading to localised flooding.
"Highest temperatures 15 to 17 degrees.
"Moderate to fresh and gusty southwest winds will be strong and gusty at the south and west coasts.
"Fresh and gusty southwest winds will be strong and gusty on parts of the south and west coasts."
And the downpours will continue as we move into the weekend, with some spot flooding possible on Saturday.
A forecaster added: "A wet start to Friday, with some heavy bursts of rain in places. But brighter by afternoon, with sunny spells and occasional showers. Top temperatures just 13 to 16 degrees.
"The weekend will be breezy and unsettled, with showers or longer spells of rain, heavy and possibly thundery at times. Rainfall expected to be well above normal.
