A freezing rain advisory is in effect for Portland, but so far metro area roads remain in good shape.
The National Weather Service issued the advisory for light icing starting at 4 a.m. Wednesday.
The main threat for freezing rain is between 6 a.m. and 10 a.m. The threat is expected to last until noon in areas closer to the Columbia River.
Fox 12 meteorologists said while they don't expect the freezing rain to last long, a few hours at most away from the Columbia River Gorge, it only takes five minutes of freezing rain to turn a dry road into an ice rink.
In Portland, crews applied 15,000 gallons of calcium magnesium acetate over the weekend to help prevent ice from forming on bridges, overpasses, tunnels, steep hills and other known trouble spots.
The anti-icing chemical will work until precipitation washes it off.
Clark County road crews were out Tuesday applying saline de-icer to roads, as well. They had been out during the last week because of the previous threat of freezing fog creating small ice patches on the roads.
Clark County uses a mix of salt and water to de-ice the roads.
The Oregon Department of Transportation warned roads can still freeze after de-icer is used. ODOT recommends drivers delay their trips Wednesday morning or take public transportation.
The afternoon commute is expected to be OK with temperatures well above freezing.
However, the Gorge won't thaw out until the late afternoon or Wednesday evening, which includes the far eastside of the metro area like Troutdale and Camas.
Fox 12 meteorologists said it's difficult to predict when the precipitation will start, because some models are showing no precipitation of any sort until 10 a.m.
