A 'SPANISH plume' of hot air is set to skim the south of the country, sending temperatures soaring over the coming days – but forecasters are warning that flash floods are on the way too.
Met Eireann is predicting very humid, warm conditions until the end of the week with the possibility of some heavy, thundery downpours at times.
"[Today] has the highest potential for heat," said meteorologist Joan Blackburn. "It should be a fine day in most places, there will be cloud about as well, but it should hold generally dry up until the evening."
Ms Blackburn is predicting temperatures of up to around 25 degrees this afternoon, however a band of thundery rain will begin moving up from the south of the country overnight, making for a wet start tomorrow.
"Over the weekend, it stays mild to warm, as such it will feel muggy," said Ms Blackburn.
"With this humid weather, you can get very heavy downpours at times," she added.
"The biggest risk of flooding is with this band of thundery rain moving northwards but anywhere that gets a thunderstorm is at risk."
Water safety experts have warned the public to stay vigilant around swimming areas while enjoying warm weather.
