A status yellow thunderstorm alert will come into effect for three counties in Munster, with the warning of potential power outages and localised flooding on Monday.
The alert for Cork, Kerry and Limerick is in place from 9am until 6pm, with Met Éireann warning of potential lightning damage and difficult travelling conditions.
While Monday is expected to start off dry with sunny spells, cloud will later build throughout the morning over much of Munster, as well as south Leinster and south Connacht.
Showers will develop, turning heavy at times with thunderstorms likely, the forecaster said, while the remainder of the country will continue to be dry with “hazy spells” of sunshine.

Highs of 19 to 24 degrees are expected on Monday, with the midlands and west of the country to feel the warmest temperatures.
Tuesday will see sunny spells and scattered showers that will be largely confined to the southwest of the country, Met Éireann said, while Ulster will experience the best of the dry weather.
Temperatures will range from highs of 18 or 19 degrees in the east to 23 or 24 in the west, with showers expected to become more isolated throughout the evening.
Wednesday and Thursday are expected to be dry in most parts with a mix of cloud and sunny spells, though there may be a “few stray showers” amid highs of 17 to 22 degrees.
Friday is expected to be another largely dry day with a few light showers possible in light west to northwest or variable breezes.
The forecaster said current guidance suggests Saturday will be a little warmer overall with sunny spells and a few scattered showers as a light southerly breeze sets in.
