A number of roads have been closed due to flooding and fallen trees following the overnight storm and heavy rain.
Police said the Markethill Road in Portadown had been closed this morning (Wednesday) after reports of cars becoming stuck in flood water.
And the Banbridge Road near Gilford is blocked at several locations due to fallen trees.
Trafficwatch NI reported that the A50 Gilford Road, Portadown (near Fullertons Trailers) is flooded, as is the B2 Drumnacanvey Road, near Drumnacanvey Lodge.
A spokesperson for ABC Council said three pallets of sandbags had been delivered to Ashgrove Road in readiness for any flooding there. Houses in the area were badly affected last year.
She said, “There is no flooding there at the moment but the River Bann is rising and continuing to rise.”
She said the council was working closely with Rivers Agency which is monitoring the areas most at risk.
The Bann towpath is currently open but the NI Fire and Rescue Service public are advising people not to walk in flooded areas.
Park Road, which was particularly badly hit in last year’s floods, is currently unaffected, due in part to drainage work carried out when the park was being revamped.
However, a Portadown man said the new pond in the park had flooded and the boardwalk across it was under water. He said, “Even at other times, the boardwalk floods. I don’t think they have built it high enough.”
Meanwhile, some rail and bus services have been disrupted and some homes in Gilford are without electricity.
In other parts of the southern division, a contraflow is now in operation on the A1 between Banbridge and Dromore due to flooding.
The A3 Belfast Rd between Magheralin and Moira is passable with care.
Motorists are also asked to exercise caution on the B10 Rathfriland Road, Banbridge, which is also affected by floods and fallen trees.
