SNOQUALMIE, Wash. (AP) - More than 30,000 people were told to leave their flood-endangered homes in Western Washington on Wednesday as rain and high winds lashed much of Washington state, causing widespread avalanches, mudslides and high water that could reach record levels.

Though the pounding rain that melted mountain snow and caused the flooding eased Thursday, flood warnings remained in effect for 14 counties in Western Washington and seven on the state's east side. The National Weather Service further warned that rain-soaked hillsides were at a high risk for landslides.

Rising waters led state highway crews to close a 20-mile stretch of Interstate 5 around Chehalis on Wednesday evening, the same area hit by a devastating flood just 13 months earlier. All three major east-west routes across the Cascade Range also were closed by avalanches and the threat of more slides.

"It's right up there with some of our most memorable flood events," National Weather Service forecaster Doug McDonnal said Thursday. "The thing that's kind of amazing in the past few years is how many flood episodes we've had."

Highway officials hoped to reopen one main route across the mountains sometime Thursday — likely Interstate 90 across Snoqualmie Pass.

"The most unfortunate part of this is all three passes are closed," state Transportation Secretary Paula Hammond said. "We're in a place until we can open Snoqualmie Pass, which is our first best hope, we're in a real bind in this state."

Flooding in December 2007 closed I-5 at Chehalis for four days and caused widespread damage in the area halfway between Seattle and Portland, Ore.

Hammond visited the scene Thursday morning and said: "It's just deja vu, I tell you. Water everywhere."

The Chehalis River was forecast to crest Thursday night and by Friday crews planned to use pumps and breach a levy to help the water drain out.

The National Weather Service issued flood warnings for about two dozen rivers in Western Washington. Amtrak passenger train service out of Seattle was suspended due to mudslides.

McDonnal said that with steady rain turning to showers in Western Washington, most rivers should drop below flood stage Friday but some, like the Chehalis, won't return to their banks until the weekend.

A record 2.29 inches of rain fell Wednesday at Seattle-Tacoma International Airport and a record 4.82 inches fell at Olympia.

Totals were even higher in the mountains, the headwaters for the rivers. Rainfall totals for the 24 hours ending at 11 p.m. Wednesday included 6.86 inches at Marblemount in the Cascade foothills east of Mount Vernon; 5.85 inches at Glacier, near Mount Baker; and 6.3 inches at Snoqualmie Pass.

The warmer temperatures and heavy rain rapidly melted snow that dumped on the Cascade mountains over the weekend. Ten inches of snow melted in a 12-hour period at Snoqualmie Pass, according to weather service meteorologist Andy Haner.

Thursday's forecast called for cooler temperatures and snow in the mountains, with 6 to 10 inches possible, and the rain to mostly end in the lowlands.

     
Fire trucks rolled through Orting, about 10 miles southeast of Tacoma, with loudspeakers Wednesday, advising everyone to leave the town and surrounding valley, home to about 26,000 people. Sandbags were placed around many downtown homes and businesses as the Puyallup River neared record levels.

Kim and Carl Scanson closed their Around the Corner restaurant when Orting police told them of the recommended evacuation. They sent employees home to care for their families.

"It's scary, but everybody works together in this town," Kim Scanson told The News Tribune as she helped pack sandbags around the city's water treatment plant.

Some residents also left their homes in the nearby towns of Puyallup and Sumner. Fife Mayor Barry Johnson suggested roughly 6,000 people voluntarily leave their homes in that city near Tacoma and Interstate 5.

Tacoma Mayor Bill Baarsma declared a civil emergency for his city of about 200,000, south of Seattle, largely because of Puyallup River flooding risks to the city's wastewater treatment plant.

State emergency officials said voluntary evacuations were recommended for Snoqualmie, a riverside town 25 miles east of Seattle, and for the southwest Washington towns of Naselle, Packwood and Randle.

The Snoqualmie River at Carnation, in the rural Snoqualmie Valley, was measured at 61.3 feet Wednesday night, 7.3 feet above flood stage and a record for measurements kept since 1932, weather service meteorologist Jay Albrecht said.

In Orting, several dozen people and a number of pets were rescued by boat Wednesday morning, Pierce County sheriff's spokesman Ed Troyer said.

Diane Knowles of Eatonville said those rescued included her 81-year-old father-in-law and her brother- and sister-in law, who in past flooding arranged for the family to bring rescue boats.

"It came up so fast this time, there wasn't really time to think about it," she said.

An avalanche of snow and mud as wide as a football field damaged some weekend recreation homes in the Hyak area east of Snoqualmie Pass. All homes at Hyak and condominium complexes at the base of the ski area were evacuated.

The debris field spanned eight houses, including one that was severely damaged, and two occupants of that home were treated for minor injuries, said Matt Cowan, chief of Snoqualmie Pass Fire and Rescue.

Chris Caviezel, who has lived at Snoqualmie Pass for about seven years, said conditions were the worst he has seen. "We're getting avalanches and we're being flooded," Caviezel said.

In Snoqualmie, kayakers paddled in the street as city officials urged residents in the flood plain of the Snoqualmie River to leave before they became trapped.

Rachel Myers stood across a flooded parking lot from her home and waited for her father to pick her up in a boat. She said her family has lived in the house since her great-grandmother built it, but they've decided this will be their last winter there.

"With flood after flood, it just gets more ruined every time," Myers said.

In the east, Spokane, already beset by more than 6 feet of snow in the past three weeks, was hit with rain and temperatures in the mid-40s, triggering a flood warning for the area. The city's schools were closed Thursday, giving its 29,000 students a third unscheduled day off this week.

In Oregon, high winds toppled trees along U.S. 26, forcing the highway's closure and stranding some motorists while crews worked to clear the road. The weather service posted flood warnings for areas along several rivers and a flood watch for all of northwest Oregon.

In Alaska, extreme temperatures — 60 below zero in Stevens Village, which is about 90 miles northwest of Fairbanks — have grounded planes, disabled cars, frozen water pipes and even canceled several championship cross country ski races.
