PORTLAND, Ore. (AP) - Another Pacific storm is pasting northwest Oregon, which last week was buried in one of the region's worst snowstorms in memory.

Rainfall that could range up to 7 inches in the mountains is threatening floods in rivers already running high with moisture from last week's storm. Making matters worse are higher temperatures that are turning more snow to water, the National Weather Service said.

State geologists said it adds up to landslide weather, too.

"Listen for unusual sounds that might indicate moving debris, such as trees cracking or boulders knocking together," the state's geology agency said in a statement. "A trickle of falling mud or debris may precede larger landslides."

The Weather Service said the storm brought high winds and seas to the Oregon coast, with gusts measured at up to 60 mph Thursday and waves that might rise 25 feet.

The National Weather Service said the storm Thursday and Friday would drop 3-to-7 inches of rain on the coast and on the Coast and Cascade ranges - 1-to-3 inches in their valleys.

The Weather Service has issued four flood warnings: for a Portland metro-area stream, Johnson Creek, and three coastal streams, the Nehalem River in Clatsop and Tillamook counties, the Wilson River near Tillamook and the Siletz River in Lincoln County.

It said the main stem of the Willamette may crest at bankful in spots, but is not expected to flood.

In the Coast Range, near Grand Ronde, Oregon 22 about four miles west of its junction with Oregon 18 was closed. The state Department of Transportation said 16 inches of water was on the road.

The heaviest rainfall was expected from Thursday afternoon through Friday, with flooding possible on rivers that rise quickly, the Weather Service said.
