LAST UPDATE | 23 Jul 2021

MET ÉIREANN HAS issued a Status Orange thunderstorm and rain warning for three counties this evening as warm temperatures continue.

A Status Yellow thunderstorm warning will be in place for the entire country from 7-8pm this evening.

The orange warning is in place from now until 7pm for counties Galway, Clare and north Tipperary. 

Met Éireann said there will be a line of intense thunderstorms moving through parts of these counties. There will be lighning, hail and toreential downpairs causing localised flooding in places. 

The forecaster said driving conditions will be “very hazardous”. 

Counties most at risk during the yellow warning are Wicklow, Kildare, Laois, Offaly, Tipperary, Clare, Galway, Mayo and Roscommon.

The warning will remain in place until 8pm today.

Heat ranging from 27 to 30 degrees is expected throughout the day with slightly cooler temperatures in east Leinster and south Munster where highs of 24 to 26 degrees are forecast due to a moderate easterly breeze.

It will be “humid and warm” tonight as temperatures won’t fall below 15 degrees.

The ongoing heatwave means that the Status Yellow high temperature weather warning for the entire country has been extended. It was due to expire this evening but will now be in place until 9am tomorrow. 

The Status Orange weather warning for Cavan, Monaghan, south Leitrim, Roscommon, Longford, and Westmeath will lift at 9am today and will revert to a Yellow warning as with the rest of the country. 

The country saw another rarity when its first ‘tropical night’ for 20 years was recorded on Wednesday. Last night was the first time a tropical night was recorded in Ireland two nights in a row.
