Met Éireann has issued a Status Yellow rain warning for six counties in the east of the country, which will be in effect for the first half of tomorrow (Monday, July 21).

The impacted counties are Dublin, Kildare, Louth, Meath, Wicklow and Monaghan.

The warning will come into effect from midnight tonight (i.e. 12:00a.m on Monday) and will remain in place for 12 hours until midday tomorrow (i.e. 12:00p.m on Monday).

Met Éireann said spells of heavy rain with a chance of isolated thunderstorms are expected in the effected counties.

Potential impacts of the rain in these areas include localised flooding; poor visibility; and difficult travelling conditions.

The UK's Met Office has also issued an equivalent 'Yellow' warning for rain for three counties in Northern Ireland.

The effected counties are Antrim, Armagh and Down.

This warning is currently in effect and will remain so until 6:00p.m tomorrow evening.

The Met Office said that heavy rain may cause some flooding and disruption during Sunday night and Monday.

In general for the coming few days in Ireland, Met Éireann is forecasting generally mixed conditions to begin the coming week, with showers or longer spells of, at times heavy, rain, with spot flooding possible. Fewer showers are expected by midweek.

It will be mostly cloudy tomorrow, Monday, with showers or longer spells of rain, heaviest over parts of Leinster and East Ulster with spot flooding possible.

Showers will become more isolated towards evening, and it will brighten up across parts of the west and south. Highest temperatures are expected to be 15° to 20° in light to moderate, occasionally fresh, west to northwest winds.

Tomorrow night any remaining rain will become increasingly confined to northeastern parts of Ulster, with a mix of cloud, clear spells and isolated showers developing elsewhere.

Lowest temperatures tomorrow night should be 10° to 13° in light to moderate westerly winds, fresh to strong on northwestern coasts.
