PORTLAND -- More snow is predicted for the Portland area but it probably won't start falling until early Wednesday morning, meteorologists said.

The National Weather Service issued a new Winter Weather Advisory that warns of heavy snowfall from 2 a.m. to 10 a.m. Wednesday for Portland, the North Willamette Valley and the I-5 corridor in Southwest Washington.

Accumulation was expected under the 1,000-foot level, but would likely be less than an inch before turning to rain in the late morning, NWS said.

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.

KGW meteorologist Nick Allard said a new storm would arrive Wednesday morning that would bring another chance for low elevation snow in eastern portions of Portland. A transition between a cold air mass on the east side of Portland and an incoming warmer air front from the coast could see more snow accumulation, Allard said.

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

"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.

Officials also recommended that drivers check road conditions on TripCheck and by listening to local newscasts before they venture out.

Along the coast range, a Winter Weather Advisory was issued, warning of snow from 1 a.m. Wednesday to 9 a.m. with 3 to 6 inches of show likely, falling near 1,000 feet.

On Mount Hood, a Winter Weather Advisory warns of steady snow showers from 4 a.m. to 4 p.m. Wednesday. Snow was expected to fall as low as 500 feet, with as much as 6 inches possible.
