Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services.
Spray and sudden flooding could also lead to difficult driving conditions and some road closures
The forecaster has also warned that some communities might become cut off if roads flood and that power cuts might occur while other services to some homes and businesses could be lost.
Greg Dewhurst, Met Office forecaster, said that some of the showers will be particularly heavy in parts of Northern Ireland.
“Those showers continue to rumble on through Sunday evening, some heavy bursts possible but they do ease by the end of the day," he said.
“And then, overnight, it’s generally dry for most with clear spells (and) just a scattering of showers, largely in the south and the west, just one or two across north-east Scotland as well.”
“We will see a risk an increasing risk of some heavy rain through western parts of the UK, a little bit of uncertainty over where this main band of rain will end up by Monday afternoon.
“Around it we’ll see a mixture of sunny spells and heavy showers. Some of these will be thundery for Northern Ireland parts of Scotland, too.
“The best of any sunnier breaks (will be) possible across eastern and south-east England and this is where we will see the highest temperatures, getting up to around 23C or 24C.”
