The aforementioned counties are at risk of local flash flooding during Tuesday, Tuesday night and into Wednesday (3rd July). Showery outbreaks of rain look set to develop during Tuesday with thunderstorms likely. These will last into Tuesday night and the worst can be expected in the Northwest. The nature of the rain is sporadic and embedded thunderstorms so locally some places could get high rainfall totals in a very short period of time.
Counties most at risk for the moment.
Donegal, Leitrim, Sligo, Derry, Tyrone, Fermanagh, Cavan
Elsewhere thundery rain will be widespread Tuesday night but probably not as heavy as in the Northwest. Having said that localised flooding here and there could not be ruled out either. Very mild, feeling humid.
