Ark. flood death toll rises to 18. Search resumes with difficulties.

A preacher whose church has cared for survivors of the flash floods that ripped through an Arkansas campground and killed at least 18 people anguished over what he would tell them Sunday as rescue teams searched for nearly two dozen people.

"You want people to escape for a moment and focus on God, but they're going to return to the reality of what they're here for," Graig Cowart, pastor of the Pilgrim Rest Landmark Missionary Baptist Church, said ahead of his Sunday morning service.

His church has been a sanctuary for survivors and relatives of those who disappeared when a pre-dawn wall of water descended on sleeping campers at Albert Pike Recreation Area on Friday, leaving them frantically trying to scramble up steep terrain in the dark.

The search for victims was suspended late Saturday as darkness amid the rocky terrain made it too dangerous to continue. It resumed early Sunday morning.

Cowart, whose church has helped shield survivors from 95-degree heat and reporters, said his service would be short and informal with a reading from the Book of Romans. He said its message about how everything comes together for God's good may help in the coming days.

The last time someone was found alive was late Friday morning. Only two bodies were found Saturday as swollen rivers subsided and anguished relatives awaiting word of loved ones grew more and more frustrated, knowing that at some point the search mission would become one of recovery.

"They're just devastated. The time for shock has probably gone and now it's just anxiety building. They're beginning to fear the worst," Cowart said.

Gov. Mike Beebe's office publicly identified 15 of the 18 victims, who include at least six young children. Five of those killed — including three children — were from Gloster, La. Three other victims also were from Louisiana, and six were from Texas.

The only Arkansas victim identified was Leslie Jez, a 23-year-old mother and wife from Foreman whose husband, Adam Jez, was listed among the flood's survivors.

"So ready to go camping this weekend," she wrote on her Facebook page Monday. "Kaden is going to love it!!" She later added: "Not looking foward to that cold water, but sounds like I might change my mind after seeing how hot it's supposed to be."

Authorities haven't said whether the child survived.

Floodwaters rose as swiftly as 8 feet per hour, pouring through the remote valley with such force that they peeled asphalt from roads and bark off trees. Cabins dotting the river banks were severely damaged, and mobile homes lay on their sides.

About 200 searchers combed some 20 miles of wilderness Saturday along the receding Caddo and Little Missouri rivers. Crews on kayaks and canoes scanned the thick brush and debris for bodies, but experts said many of those killed could be trapped under fallen trees and rocks, and that the water likely won't be clear enough to see through for several days.

Tom Collins, a Spring Hill volunteer firefighter, said the debris in the water was frustrating their attempts to recover bodies, and that there were so many fallen trees that it looked like a beaver dam.

"It's just a tangled mess," Collins said.

Other searchers rode out on horseback and ATVs to scan the heavily wooded area and rocky crags along the rivers, where debris hung as high as 25 feet up in tree branches. Poor cell phone service and visibility from the air hampered search efforts. Portable cell towers were dispatched to the area in the hope that stranded survivors would be able to call for help.

Beebe said many of those thought to be missing are people whose relatives called saying they believed they were camping in the area, but weren't sure. He said officials are running the license plate numbers of vehicles found in the area to try to contact their owners.

A register that would have showed who was staying at the campground was washed away in the flood, and a call center fielded inquiries about 73 people.

U.S. Sen. Blanche Lincoln, Agriculture Secretary Tom Vilsack and U.S. Forest Service Chief Tom Tidwell toured the devastated area, and President Barack Obama expressed his condolences to the victims Saturday and offered Arkansas federal assistance.

Forecasters had warned of the approaching danger in the area during the night, but campers could easily have missed the advisories because the area is isolated.

The last body found Friday night was retrieved 8 miles downstream from the campground, and authorities Saturday combed the headwaters of Lake Greeson, a large body of water about 20 miles from the camp that would be the furthest any of the bodies could travel.

The search was expected to take several more days, or even weeks.

"This is not a one- or two-day thing," said Gary Fox, a retired emergency medical technician who was helping identify the dead and compile lists of those who were unaccounted for. "This is going to be a week or two- or three-week recovery."
