Heavy rain and strong winds could turn roadways into streams, according to a hazardous weather outlook issued early this morning by the National Weather Service in Portland.
The steadily pouring water could sweep road debris in front of drains, allowing untethered creeks to grow.
The weather warning was issued hours into a strong Pacific storm expected to last through the day.
Wind is expected to blow steadily between 10 and 16 mph, with some gusts registering as high as 24 mph.
