A pensioner was left badly shaken after a tree fell into his garden in Broomhill Avenue in Derry on Monday night.
Samuel Douglas, who is 88-years-old, said it was "very distressing" for both himself and his wife.
"The tree was in our garden, it's the second time it's happened in six months. We are worried out of our wits about these trees," he said.
"The tree is right up against the wall, we are fortunate the windows didn't break. If this had happened later on when children are around someone could have been killed."
NIE said the power supply in the North West had been affected by the weather. There are reports of faults at Campsie and Sheriffs Mountain.
