Scores of homes in the Lissan area have been without power since just after 9am this morning following a fault caused by storm Doris.
Northern Ireland Electricity says it has been working hard to fix around 250 separate faults caused by the high winds and rain since the early hours.
In relation to the Lissan fault, no estimated time of a fix has been given, but the company said: "A repair team has been assigned and will be on its way as soon as possible.
It added that: "The fault is due to severe weather conditions causing damage to the network."
Around 57 homes in the area have been affected, while in Carrickmore a further 33 customers are also without electricity.
NIE said just an hour ago that it has already restored power to 17,000 NI homes.
Storm Doris, which has also felled trees near schools, GAA gorunds and on main roads in areas of Mid Ulster, is expected to ease this afternoon.
But until then a yellow warning remains in place throughout Northern Ireland.
