Lanes of several other highways throughout the region were flooded, forcing motorists to swerve to avoid the water.

BART trains were also delayed by as much as 20 minutes because of wind and rain requiring trains to run at slower speeds, in addition to medical emergencies involving passengers in crowded trains running through the Transbay Tube, BART officials said.
