Yet more rain is expected to fall on an already saturated Northern Ireland in the next few days.
The news comes as villagers and visitors in Strangford, County Down, were surprised on Sunday by an unusually high tide.
A small number of cars were stranded and the Strangford Lough Ferry was forced to switch docks to accommodate vehicles and passengers following the flooding.
A spokesman for the Met Office said that up to 10mm, or half an inch, of rain is expected to fall from dawn today over areas of County Fermanagh, where residents have already suffered flooding after heavy downpours in recent weeks. Large tracts of land and dozens of roads were left under water when Lower Lough Erne reach-ed its highest level on record.
He added that tomorrow is expected to be “miserable”.
“There is an area of low pressure and around 10mm of rain forecast for areas including Fermanagh,” he said. “This isn’t usually an amount which would prompt a weather warning but it will add to already affected areas.”
