THE country has been warned to brace itself for flash flooding with prolonged spells of rain set to dampen the country until the weekend.
While blizzards have wreaked havoc across the north east of the United States, here brollies and raincoats will be in widespread use – with Wednesday set to be the wettest day this week.
After a very wet Sunday which saw players and spectators drenched at the Ireland v England rugby clash, more heavy rain is on the way.
Weather chiefs said flooding could arise due to "heavy and persistent rain" across Leinster and Ulster.
Much of the country will experience gloomy conditions until Thursday, with cold temperatures potentially turning showers to sleet and snow.
While today saw persistent drizzle and overcast conditions, tomorrow looks like being mostly cloudy again, with a few bright or sunny spells during the morning, Met Eireann said.
Most areas will stay dry during daylight, but rain will spread in from the west during the afternoon.
"Tomorrow evening the rain in the west will cross the country and it will be very wet on Wednesday – it will be the wettest day of the week," a Met Eireann forecaster said.
Asked if there would be flooding, he said: "It's hard to say, but you could have spot flooding."
The rain will clear from the west during Wednesday afternoon and evening.
Strong southerly winds will veer southwest as the rain clears.
"Apart from well scattered showers near north and west coasts, Wednesday night will be dry, though cold with slight ground frost," the Met office said.
Thursday will be "a cool bright day" with sunny spells and scattered showers – with the showers most frequent across Western counties.
Westerly winds will be "fresh and gusty."
But the weekend looks like being mainly dry. Both Friday and Saturday will be cold, bright days with sunny spells and winds will be light.
However, night frosts will be widespread and sharp, "with sub-zero air and ground temperatures," Met Eireann said.
