Met Éireann issues countrywide weather warning ahead of August deluge with 'saturation' forecasted

KILKENNY

Heavy rain will push in

Met Éireann has put the country on alert for thunderstorms ahead of what is expected to be a very wet spell of weather in Ireland.

The weather forecaster has issued a Status Yellow thunderstorm warning for all of Ireland which is not good news for staycationers or the outdoor summer Covid-19 containment strategy.

It warns of: "Thundery spells of rain with the risk of lightning and local hail". The forecaster cautions that this could result in  "locailsed flooding and hazardous driving conditions".

The alert is valid from 6am to 7pm on Thursday, August 5.

The forecast outlook from Met Éirenn says it will remain unsettled over the rest of the week, the weekend, and early next week with widespread heavy or thundery showers and a continued risk of spot flooding.

The forecaster's farming section says temperatures will cool slightly in northwesterly winds over the weekend before warming again as we move into next week.

They add that sunshine will be below average over the coming week with unsettled conditions. The farming section adds that the above average rainfall will mean that by Friday, land on half the country will be "close to saturation". More below Tweet.
