Frequent lightning strikes and hail may also be seen, the Met Office’s yellow thunderstorm warning said.

The Met Office has issued a thunderstorm warning for counties Fermanagh, Tyrone, and Derry from 8 am until 9 pm today.

Some parts of the west could potentially see up to 30mm of rain in one hour and up to 60mm in a two-to-three hour period.

The Met Office said, “Areas of rain, perhaps heavy, are likely to develop quite early on Tuesday, probably breaking down into slow-moving heavy showers and thunderstorms during the late-morning and the afternoon.”

“Showers and storms should ease into the evening.”

In certain areas, lightning and hail could be secondary risks.

Amy Bokota, a Met Office forecaster, said: “The downpours could be slow moving, and that’s the main trouble, the wind’s quite light at the moment so when they do form, they could be quite slow moving and intense.”

She added: “Where you see them they could be quite intense and dramatic, but not everywhere’s going to see them and some places just down the road could be completely fine and shower and thunderstorm-free.”

It will come before an area of low pressure approaches the UK from the east on Wednesday, bringing heavy, prolonged rainfall to eastern parts of the country.
