Local businesses in Carrick-on-Shannon, Co Leitrim are on high alert after the River Shannon flooded following heavy rain fall.

The car park at Carrick Retail Park has been partially closed to shoppers, however, all retail outlets in the park remain open and Leitrim County Council is advising property owners in vulnerable areas to monitor the situation and take precaution.

The council said that its emergency management team met this morning to assess water levels on the River Shannon and surrounding waterways. 

It said that it will continue to monitor the impact that rainfall, both recent and forecast, will have on the water levels on the Shannon in the area. 

A number of farm yards and roads in the Golden Island area of Athlone in Co Westmeath have been flooded.

Farmers in the area and residents on the Strand in the town have put additional flood barriers in place as preventative measures.

There is growing concern in the area over the effects of prolonged rainfall in the last 24 hours and Westmeath County Council has put additional staff on standby.

The council said that water levels on the River Shannon are around 1m below the highest level recorded during the winter of 2015-16.

It said that permanent flood defences already in place "will provide significant protection to areas of the town that were affected in the past."

Meanwhile, a Status Yellow rainfall warning is in place for four western counties - Donegal, Leitrim, Mayo and Sligo - with 25 to 35mm of rain expected today and during the early hours of tomorrow.

Met Éireann said that as the ground is saturated and river levels are elevated, the rainfall may lead to localised surface and river flooding.

There is also a Status Yellow wind warning for Donegal, Galway and Mayo.

Southwesterly winds are forecast to reach mean speeds of 50-65km/h at times, with gusts of 80-95km/h.

There is a slight risk of localised coastal flooding as a result.

Both warnings came into force at 3am today and are valid until 3am tomorrow.

A further Status Yellow wind warning for Donegal has been issued for tomorrow. It comes into place at 6am in the morning and will remain in place until 8pm tomorrow evening.

Meanwhile, a Yellow rain warning is in force for three counties in Northern Ireland until 9pm today.

The Met Office said heavy rain is likely to lead to travel disruption in counties Derry, Tyrone and Fermanagh.

Yellow wind, snow and ice alerts have been issued for tomorrow for western areas of Northern Ireland.
