Well, it's time to pack away the parasols, and replace them with umbrellas.
The Status Yellow Thunderstorm warning that had been issued across Ireland has now been escalated to a Status Orange warning.
Met Éireann changed the warning on Sunday (14 August).
"Due to the sporadic nature of development, not all areas will be affected," Met Éireann said.
"Heavy downpours of rain and hail will occur in places. Flooding where heavy downpours occur."
A few isolated heavy showers or thunderstorms are expected during the day on Sunday, but they will gradually increase in coverage through the late afternoon and evening.
Intense lighting and hail is predicted.
Scattered heavy showers and thunderstorms are also predicted to continue overnight.
The warning remains valid from 3pm on Sunday until 9am on Monday morning (15 August).
"On Monday scattered showers and thunderstorms will continue to affect the southern half of the country mostly, becoming intense through the afternoon with the continued risk of flooding," Met Éireann forecasted.
"It will be fresher, but drier further north with just isolated showers and intermittent sunny spells. Highest temperatures will return closer to average, ranging from 15 to 17 degrees in the north and northwest to between 17 and 23 degrees elsewhere."
A Status Yellow High Temperature warning remains in place for
Leinster,
Cavan,
Monaghan,
Munster,
Galway and
Roscommon.
It will continue to be very warm on Sunday, with maximum temperatures of between 27 to 30 degrees, with some areas possibly reaching higher again.
It's set to be warm overnight, with temperatures remaining above 15 degrees at minimum.
Met Éireann is warning the public to be aware of the dangers posed by heat stress, especially for the more vulnerable of the population.
The meteorological organisation is also warning the public of the High Solar UV index, and the increased risk of water related incidents.
