The Antrim coast has been hit by high winds

Most of the houses affected were in counties Tyrone, Fermanagh and Antrim.

Julia Carson from NIE said the weather was not as bad as they had feared. "The weather warning didn't reach the levels predicted," she said.

"The network held up very well, it is very robust and again these are very exposed rural and coastal locations."

The Foyle Bridge, which was closed for a time because of the high winds, reopened at midnight. A 30mph speed restriction is in place.

Roads Service said a total of five fallen trees had been reported overnight.
