All San Francisco Municipal Railway cable car lines are being served by buses instead this morning because of the rainy weather, according to Muni officials.
The agency stopped service on the cable car lines as a precaution and will restore service when the rain eases up, Muni spokesman Paul Rose said.
Cable car lines also experienced a partial shutdown Monday afternoon, but that issue was caused by a mechanical problem that developed in the area of Powell and Bush streets.
The Powell/Mason and Powell/Hyde lines switched back to avoid the problem area while repairs were made.
Muni officials are warning riders to expect delays today as buses and light-rail trains operate at reduced speeds during the stormy weather.
