"These thunderstorms are going to be violent in nature, they’re going to lead to frequent and intense lightning.

“They’re going to lead to very large hailstones in excess of five to seven centimetres, so that’s golf ball size and even a little bit bigger which can cause damage.

“It’s going to lead to flash flooding in some areas as well, given the mountainous terrain in this region. there is a history of flash flooding in parts of Donegal and today is likely to be the case as well.

“50mm to 100mm of rain falling within a matter of a couple of hours is going to lead to some flooding concerns.

“There is also the risk of some very strong winds, so these storms because of the powerful down drafts that they generate, they lead to squall winds as well which could go to 110kmh in some instances, perhaps causing some damage.

“As well as that, we have to mention that there is a very outside chance of a tornado event in this area as well.”
