Like Met Éireann, the Met Office has issued weather warnings for the incoming weather. It says a 'deep area of low pressure' is on its way.

The UK forecaster has tweeted a short video which shows a very unsettled front which is set to last through to Sunday. It forecasts unseasonably strong winds, heavy rain and thunderstorms. More below tweets.

Met Éireann has already issued a Status Yellow weather warning for Thursday into Friday. The warning says heavy rain will spread from the south Thursday evening and night. Because accumulations of 25 to 40mm will occur over a relatively short time, the forecaster is warning of spot flooding is likely.

The warning is valid from 7pm Thursday, August 8 to 7am Friday, August 9.

It has also tweeted out what to expect in a seven-day forecast video.
