Electricity is off for some customers in the Twain Harte and Cedar Ridge areas after a large oak tree fell today.
Power lines and cable lines were damaged in the fall.
Bob Kempvanee from Twain Harte Fire says the tree is causing power problems.
Black Oak Road will be closed to thru traffic from Muir to Fuller for a while today.
The outage is on the Muir side, and drivers can come in on the Fuller side but they can´t get all the way through.
Officials say it could be a couple of hours before the large oak tree is completely removed.
