Police and fire officials responded to the area just after 7 p.m. and cautioned residents to stay inside their homes and to avoid contact with the high-voltage lines.
PG&E spokesman Joe Molica said a tree took down multiple spans of wire and utility crews responded to make repairs. Crews de-energized the lines shortly after 8 p.m. but remain in the area making repairs. Twenty-four customers were without power at 10 p.m. due to the weather-related incident, Molica said.
A Contra Costa Fire Protection District dispatcher said fire crews left the area at about 8:45 p.m.
