If you’re heading out this weekend, don’t forget your brolly, it’s going to be a bit crap.

A warning for thunderstorms and rain has been issued for 15 counties.

The status yellow alert will impact all of Leinster, Cavan, Donegal and Monaghan tomorrow.

The warning will kick in at midday and run until 8pm.

Heavy showers are being forecast with the chance of localised thundery downpours that may lead to spot flooding.

Meanwhile, a similar warning will be in place for all of Northern Ireland.
