Met Éireann weather chart shows the extent of the rain expected

Met Éireann has issued a Status Yellow rain warning for many parts of Ireland as a band of weather that includes sleet and snow is swept across the country raising flood risks further.

The Status Yellow alert applies to parts of all four provinces: Dublin, Kildare, Laois, Longford, Louth, Wicklow, Offaly, Westmeath, Meath, Clare, Tipperary, Cavan, Monaghan, Donegal, Galway, Mayo, Leitrim, Sligo and Roscommon. 

The warning says the rain will last from Sunday night and into Monday morning will lead to accumulations of between 20 to 25mm, with higher totals possible in upland areas.

Met Éireann says the rain is likely to be preceded by a period of sleet and snow in parts of Connacht, Ulster and north Leinster, before turning to rain later in the night.

"As the ground is saturated at the moment and river levels are elevated the combined effect of rainfall and snow melt may lead to some localised surface and river flooding," said the forecaster's warning.

The warning which was issued on Sunday morning is valid from 8pm on Sunday, February 23 to 8am on Monday, February 24. More below tweets.
