National thunderstorm warning issued
Warning valid until tomorrow evening
Met Eireann has issued a thunderstorm Warning from this evening until 9pm tomorrow.
Thunderstorm activity is expected this evening, overnight and again during the day tomorrow.
Some intense thundery downpours are likely at times, with possibly some flash flooding in places, according to Met Eireann.
Connacht and west Ulster will be most at risk this evening.
But all areas will be at risk later tonight and especially during Tuesday, forecasters say.
Some local spot flooding could prove a risk over the next 24 hours.
The scattered heavy showers and thunderstorms will die out on Tuesday night however.
The weather will become dry countrywide with some mist and shallow fog patches forming.
