TWIN FALLS (AP) - Rescue crews are hoping the weather improves and the risk of flash flooding lessens enough to resume the search for a Canadian man who has been missing for seven weeks in the rugged, high desert mountains along the Nevada-Idaho border.

Efforts to find 59-year-old Albert Chretien were suspended Tuesday by rain, low clouds and flood warnings in a remote corner of Elko County, Nev., where Chretien and his wife became stranded along a muddy road on a trip to Las Vegas.

Meanwhile, Rita Chretien continues to recover after being rescued Friday by a group of hunters.

After surviving seven weeks in the mountains by rationing trail mix and hard candy, Rita Chretien, 56, is back to eating solid food, consuming salmon and green beans for dinner Monday and a breakfast burrito and homemade salsa Tuesday at a hospital in Twin Falls. Doctors upgraded her condition to good.

"Her spirits are high," said Ken Dey, a spokesman for St. Luke's Magic Valley Medical Center. "The medical team is watching her closely, but indicators of her recovery are very good."

The hospital said it wasn't certain yet when she would be discharged.

The couple from Penticton, British Columbia, is believed to have turned off a highway and onto a northeastern Nevada mountain road looking for a shortcut to Jackpot, Nev., a stop on their way to a Las Vegas trade show. When their van became stuck in the mud, Albert Chretien set out on his own with a GPS, hoping to walk more than 20 miles to the town of Mountain City. He never returned.

Rescue teams were eager to head back to the rugged backwoods of Humboldt-Toiyabe National Forest, the largest forest in the lower 48 states at 6.3 million acres, to continue their search for Albert Chretien.

If weather allows, deputies will use new information gathered from their interview with Rita Chretien and the hunters who rescued her to pinpoint their search today.

On Monday, two teams slogged through tough conditions as part of their hunt. One group was helicoptered into the site where the van was found; another on horseback and all-terrain vehicles trekked up dirt roads outside Mountain City.
