KGW meteorologist Nick Allard said to expect the rain to end about 9 a.m., with clearing and dry skies by noon.

All that rain led to localized flooding in the city's core, and to power outages. At one point, 3600 PGEcustomers in Marion County were without power, leaving traffic signals dark at some intersections.

KGW crews found City of Salem work crews traveling from intersection to intersection, setting up portable generators to power traffic lights.
