PORTLAND -- KGW meteorologist Nick Allard said to expect a rain and snow mix to continue through Tuesday afternoon at lower elevations but no accumulation. Above 500 feet, a trace or up to three inches could stick.

Crews with the Portland Department of Transportation said they were applying de-icer to some areas where it won't wash off. They were also patrolling hills, bridges and overpasses that seem to always be trouble-spots during snow storms.

"You'll remember that it is not effective to apply anti-icer if it rains or in very wet snow as it simply washes off the road surface. Also, there must be at least an inch of snow for plows to be useful," explained Cheryl Kuck, with the Portland Bureau of Transportation.

Along the coast range, a Winter Storm Watch was in effect through 4 p.m. and as much as 4 new inches of show were expected, falling as low as 500 feet.

Allard said said a new storm would arrive Wednesday morning that would bring another chance for low elevation snow in eastern portions of Portland.

PDOT crews said they were planning to apply more de-icer overnight. Plows and sanders were also put on standby for overnight snow duty.
