Flooding in parts of Northern Ireland after bursts of heavy rainfall across the province - Met Office Weather Warning in place

Heavy rain as led to flooding on a number of roads across Northern Ireland – with a weather warning for more rain in place until this evening.

Police said the M12 off the M1 at Portadown is closed as a result of the heavy rain.

The country bound lane is currently impassable at Portadown (junction 12) due to heavy rainfall, and police are asking motorists to come off the motorway at junction 10. A further update will be provided in due course.

On Sunday night police advised drivers that the Marble Arch Road, Florencecourt and Sligo Road, Enniskillen were both impassable due to floods.

Police also said flooding was affecting other parts of west Fermanagh and urged drivers to slow down, and exercise caution on affected roads.

There were also reports that the main Enniskillen to Dublin Road in Enniskillen, County Fermanagh is suffering flooding.

Parts of Belmore Street, near the town's war memorial, were submerged in water on Sunday evening.

The Met Office has issued a yellow-level rain warning for the eastern part of Northern Ireland.

The region was expected to experience some of the worst of a heavy spell of rainfall until 6pm Monday.

Forecasters predict affected areas could see half a month’s worth of rain in less than a day after a warning was put in place for Antrim, Armagh and Down for the 24 hours from 6pm on Sunday.

A more intense amber-level warning temporarily put in place overnight has since been lifted.

The Met Office warned there is a risk that homes and businesses could be flooded.

The expected rainfall carries a risk of flooding, power cuts and dangerous driving conditions.

Forecasters also warn there is a small chance that some communities could be cut off by flooded roads while fast-flowing or deep floodwater could pose a danger to life.

Simon Partridge, a forecaster with the UK Met Office, said: “It looks like Northern Ireland is the place where we could see the most rainfall and certainly the most impactful rainfall.

“They could see 50 to 75mm of rain within 12 to 18 hours.”

Flooding was already affecting routes in Fermanagh on Sunday evening, with the Marble Arch Road, Florencecourt, and Sligo Road, Enniskillen, both described as impassable by police.
