Authorities in San Mateo County are alerting motorists of a road closure in the Portola Valley area.

A stretch of Old La Honda Road south of Skyline Boulevard is closed because a tree has fallen on a power line, county emergency officials said.

Shortly before noon, county officials said they expected the road to be closed for about two more hours. Repair crews are at the scene.
