Lightning strikes are being reported by Met Éireann across Ireland as the short heatwave that has brought 100 year high temperatures is beginning to ease.

The forecaster has issued two contrasting weather warnings - one for heat and a second for thunderstorms which is bringing lightning and has the potential for flooding in parts.

Status Yellow high temperature warning for Leinster warns of daytime temperatures of 25 to 28 degrees. It expires at 7pm on Tuesday, July 19

A Status Yellow warning for thunderstorms for southern and eastern areas warns of localised heavy rainfall which may cause some localised flooding. It covers Carlow, Kilkenny, Wexford, Wicklow, Cork, Tipperary, Waterford. It expires at 9pm on Tuesday, July 19.

The outlook for the rest of the week is for temperatures to return to normal with a fair amount of dry weather apart from a few showers or patchy light rain. However, it will turn wetter this weekend as Atlantic weather systems take hold. MORE DETAILS BELOW TWEETS.
