Met Éireann has issued a weather warning with heavy rainfall forecast across the country this evening and tomorrow.

Munster and Connacht are to be the worst affected, experiencing up to 60mm of rainfall, while Leinster and Ulster will experience 30mm-50mm of rain.

The Irish Coast Guard is warning of dangerous conditions, while the Road Safety Authority is warning drivers to be careful of excess water on the roads and flooding in places.

According to RSA CEO Noel Brett, the recent dry weather could make roads particularly hazardous - the resulting build up of rubber and oil deposits, combined with the rainwater, increasing the risk of skidding.

The authority is advising motorists to slow down and to allow for poor surface conditions.

The Irish Coast Guard says the combination of tides, high winds and swollen rivers may lead to dangerous conditions.

It is urging people not to cross fast running rivers or floodwater fords, to be aware of hazards in urban areas including submerged manholes and downed power lines, to stay away from the shoreline, and not to engage in watersports.

The west and the south of the country will experience the worst of the weather, but heavy rainfall is forecast countrywide, with more rain is expected tomorrow.
