Thousands of residents in the B.C. Interior were without power Monday morning after a lightning strike hit part of the power grid feeding the area.

A lightning strike at 3:20 a.m. PT hit part of the power grid feeding the North Thompson Valley, B.C. Hydro spokesman Dag Sharman said.

For most of Monday morning, power was out from a point 20 kilometres north of Kamloops all the way to Valemount, roughly 300 kilometres north.

Sharman said hydro crews had to rebuild a transmission tower before the line could be re-energized.

Power was restored to most homes by noon Monday.
