PORTLAND Temperatures around the metro area hovered around freezing early Monday morning but little of the dreaded freezing rain that led to a Freezing Rain Advisory through noon today.

The National Weather Service advisory warned that freezing rain may further coat road surfaces and create dangerous driving conditions, as well as risks for walkers. Safety cannot be understated. Please do not go under trees. Tree limbs and even whole trees can fall with little notice and potentially kill you when coated with ice, it said.

It also warned of danger on high bridges and then just before 9:30 p.m., crews closed down the northbound I-405 ramp onto I-5 coming off the Fremont Bridge, due to ice.

People in the Columbia River Gorge have been facing an even bigger threat. While Portland did warm above freezing for a time Sunday, the gorge never did, leaving that area coated with ice. Chains are required for all big rigs headed east on I-84.

I was driving 20 miles an hour with chains all the way from basically Colburn to Troutdale, said trucker Daniel Cundif. It was just a really slow drive and then you've got these people just driving like idiots and wrecking.

A Freezing Rain Advisory for the central Columbia River Gorge and Upper Hood River Valley warned of possible freezing rain, sleet and snow through Monday night.

Monday's freezing rain will follow four days of difficult weather conditions in the gorge, as well as throughout the Portland and Vancouver Metro areas.

On Sunday morning, the city used the federal Emergency Wireless Alert system to put the word out to people on their mobile devices to stay home and avoid icy roads.

The ice even forced TriMet to shut down Saturday night. Then, they started back up on a limited schedule Sunday afternoon.
