THE heavy rain throughout the country is causing travel chaos, with delays of several hours being reported in parts of the country.
Met Eireann has issued a rainfall warning valid until midnight tonight, with heavy rain expected over south and east Leinster and in south Munster.
Up to 50mm of rain is anticipated in some parts of the country.
Excess surface is water is also causing delays in both directions on the M50, with traffic reported as being 'bumper to bumper' in parts.
AA roadwatch has also reported several accidents on the road.
Delays close to Dublin's Eastlink bridge are reported to be up to an hour.
Cork City Council has this evening issued a flood warning, while commuters travelling on the N2 are experiencing delays as flooding is affecting Ardee in Co Louth.
Earlier this afternoon a truck crashed on the M9 Waterford/Dublin Rd.
Although the accident has since been cleared, heavy delays are still being experienced in the area with excess surface water on roads.
Although temperatures are set to remain in the mid-to-high teens, the stormy weather will only get worse as Met Eireann has issued a yellow national and marine warning.
“Warnings have been issued for rainfall of an estimated 25-50mm. Counties worst affected will be in the south Munster area, such as Kerry and Cork. However, other more northern areas will also be hard hit, particularly south and south east Leinster,” a Met Eireann source told Independent.ie.
Southeasterly winds have also been forecast as ‘moderate to fresh’ for this afternoon as the national forecaster warns small crafts at sea of the potential danger.
According to the source, the rain will be heaviest in the south and south east of Ireland today, with Co Wicklow and Co Wexford worst affected by the weather.
More northern countries, including Dublin, will continue to get the heavy showers this afternoon and 25-50mm of rainfall is expected to accumulate.
"The band of rain at the moment is currently pretty heavy. And while the south west and west of the country will become clearer by the evening, there are further bouts of rainfall expected for the east of the country,” according to the Met Eireann source.
AA Roadwatch have warned motorists to be extra vigilant on the roads today as driving conditions are affected by the heavy rain.
According to the AA website, there is "excess surface water on the M9 Dublin /Waterford Rd between J10 Knocktopher and J11 Mullinavat".
Earlier this week, the wet weather caused traffic chaos for commuters as surface water and extra cars on the roads resulted in higher than average collisions and blockages.
At that stage, Met Eireann has issued a gale warning and predicted rainfall of up to 30mm.
Nonetheless, we are expected to get some respite from the dismal conditions over the weekend, according to the forecaster.
"The relatively warm weather will stay with us and it will be a much brighter day tomorrow."
"There will still be some showers but temperatures will be between 15 and 17 degrees. It will be slightly cooler on Sunday, but apart from a few scattered showers, the day will remain bright and mild."
