Heavy freezing fog created icy roadways throughout the Portland and Vancouver area on Wednesday morning.
Portland Public Schools - the state's largest school district - first announced a two-hour delay, but then canceled classes for the day as a result of the dicey driving conditions.
"It just comes down to safety. We just don't want to take any chances with our students, our staff and our teachers," said Christine Miles, a spokeswoman for Portland Public Schools. "Principals and teachers, we're advising them to use their own discretion. Each area is different."
Portland transportation workers put more than 5,000 gallons of de-icer on the roads overnight in hopes of making the commute a little easier Wednesday.
Meanwhile, in southwest Washington, Vancouver, Evergreen and Washougal schools all closed for the day, citing the ice on the roads.
In Vancouver, Clark County sheriff's deputies said there were several collisions after the freezing fog created black ice and hazardous driving conditions.
Nearly six days straight of freezing temperatures, plus snow in the region, has made for an eventful week of weather in Oregon and southwest Washington, but Wednesday morning's commute may have been the trickiest of them all for some drivers due to the freezing fog and black ice.
