(5 p.m., Monday, Jan. 16, 2017) The National Weather Service has issued a freezing rain advisory for the Portland metropolitan area. The current forecast calls for freezing rain to start early Tuesday morning and last at least into Tuesday afternoon. Up to 0.4 inches of ice accumulation is likely. Based on this forecast, the Portland Bureau of Transportation warns the traveling public to be prepared for severe winter weather that may create hazardous traveling conditions during the Tuesday morning commute.
The Weather Service has also advised that freezing rain is likely to last the longest, with more ice accumulation, in areas East of Interstate 205.
Drivers should be aware that freezing rain creates treacherous travelling conditions. If possible, travelers should avoid all travel unless absolutely necessary. Travelers should monitor conditions closely throughout the day.
PBOT is closely monitoring conditions and will bring on extra crews starting at 3:30 a.m. Tuesday morning to put down sand and gravel at critical intersections. Travelers should still be prepared for very slippery conditions.
Watch for black ice
Black ice is defined as ice that remains on roadways that are not subjected to direct sunlight. Black ice commonly forms on roads that wind around lakes and rivers, in tunnels, on overpasses and in highly shaded, rural areas. Black ice is almost invisible to the naked eye. Be especially careful when driving or riding into shaded areas, on bridges and overpasses, and on infrequently traveled roads. Slow down during your approach.
Look out for people walking and biking
Be watchful for pedestrians and bicyclists who are also trying to get around in hazardous, low visibility conditions. Share the Road safely and responsibly.
Carry an emergency weather kit
Carry an emergency weather kit in your vehicle to help keep you safe and more comfortable during long waits. Your kit should include chains, battery jumper cables, first aid kit, shovel, basic tools (pliers, wrench, screwdriver and knife), blanket, extra clothing (hats, socks, boots, and mittens), flashlight, bag of sand, and cellular phone or CB Radio.
