Winter Storm Watch

Statement as of 5:04 AM PST on January 16, 2017

Expires 9:00 PM EST on January 17, 2017


... Winter Storm Watch in effect from Tuesday morning through
Tuesday afternoon for the valleys below 2000 feet in the north
Oregon Cascades and foothills...

The National Weather Service in Portland has issued a Winter
Storm Watch for significant icing in the valleys below 2000
feet... which is in effect from Tuesday morning through Tuesday
afternoon.

* Timing... rain is expected to develop Tuesday morning...
increasing throughout the day. Subfreezing air trapped in the
Cascade valleys will likely cause freezing rain and significant
ice accumulation Tuesday morning. Valley temperatures are
expected to slowly climb above freezing Tuesday afternoon...
ending the freezing rain threat Tuesday evening.

* Ice accumulation... valley ice accumulation of up to one third
of an inch. Ridgetop temperatures will be significantly
warmer... so no significant icing is expected in the higher
terrain.

* Impacts... several days of very cold temperatures will make
ground surfaces like roads and sidewalks very receptive to ice
accumulation. It may take a couple hours of temperatures above
freezing to completely end the freezing rain threat at any given
location. Ice accumulation on trees and power lines may result
in downed branches and lines... which would bring the threat of
power outages Tuesday.

Precautionary/preparedness actions...

There is a potential for significant ice accumulations. Future
driving... bicycling... and walking conditions may become
hazardous... so it is important to monitor the latest forecasts.
Also... be prepared for potential power outages as ice may bring
branches and power lines down Tuesday.
