Homes were flooded and roads blocked in many parts of Ballymena on Sunday evening following a couple of hours of heavy rainfall.
The torrential rain, which was accompanied by prolonged thunder and lightening, badly hit homes in the Harryville area and saw homes in Toome Road/Queen Street flooded for the fifth time in six years.
There was anger amongst residents as drains struggled to cope with the deluge which also caused power cuts.
It is understood some residents had to leave their homes and were only able to return after the Fire and Rescue Service pumped the flood water away.
Other parts of the town which were badly affected were Smithfield, Larne Road, Wakehurst, Demesne and Tullymore Park.
