PIGEON FORGE, Tenn. — Raging wildfires fueled by high winds forced the evacuation of thousands of people and were believed to have wiped out an entire resort of more than 100 buildings in the Great Smoky Mountains as National Guard troops arrived early Tuesday to help overwhelmed firefighters.

Rain had begun to fall in some areas, but experts predicted it would not be enough to end the relentless drought that has spread across several Southern states and provided fuel for fires now burning for weeks in states including Tennessee, Georgia and North Carolina.

The storms appeared to be taking aim at the nearly 28,000-acre Rough Ridge Fire in north Georgia and the nearly 25,000-acre Rock Mountain Fire that began in Georgia and then spread deep into North Carolina.

Rain showers ended in the Gatlinburg, Tennessee, area about 8 a.m. Tuesday, said National Weather Service meteorologist Sam Roberts. He said no more meaningful rainfall was expected until about midnight Tuesday, and would last through Wednesday.

Based on preliminary surveys of the area, the Westgate Smoky Mountain Resort & Spa in Gatlinburg "is likely entirely gone," the Tennessee Emergency Management Agency said in a news release. The agency had previously said it had reports that the Ober Gatlinburg amusement park and ski area had been destroyed as well, but later said resort officials had checked in and said the property was fine.

Dollywood representatives say the theme park hasn't been damaged by wildfires, but more than a dozen cabins operated by the park have been damaged or destroyed.

Dollywood has suspended park operations at least through Wednesday. Its DreamMore resort will be open on a limited basis as a shelter and for registered guests.

Hundreds of homes and other buildings, including a 16-story hotel, also were damaged or destroyed by flames.

Emergency officials ordered evacuations in downtown Gatlinburg and Pigeon Forge and in other areas of Sevier County near the Great Smoky Mountains. About 14,000 residents and visitors were evacuated from Gatlinburg alone, officials said.

No deaths have been reported, though several people were hospitalized with burns, emergency officials said in the news release.

Officials say there are about 1,200 people sheltering at the Gatlinburg Community Center and the Rocky Top Sports Park. Several other shelters have opened to house those forced from their homes. TV broadcasts showed residents streaming out of town just as rain started to wet roads.

Workers at an aquarium evacuated because of the wildfires were concerned about the thousands of animals housed there. Ryan DeSears, general manager of Ripley's Aquarium of the Smokies, told WBIR-TV the building was still standing and all workers had been evacuated late Monday. However, he said workers were anxious to return to check on the well-being of the 10,518 animals.

The rain forecast "puts the bull's-eye of the greatest amounts right at the bull's-eye of where we've been having our greatest activity," said Dave Martin, deputy director of operations for fire and aviation management with the southern region of the U.S. Forest Service.

The projected rainfall amounts "really lines up with where we need it," Martin said Monday. "We're all knocking on wood."

After weeks of punishing drought, any rain that falls should be soaked up quickly, forecasters said. It will provide some relief but won't end the drought — or the fire threat, they said.

Drought conditions will likely persist, authorities said. The problem is that rainfall amounts have been 10 to 15 inches below normal during the past three months in many parts of the South, authorities said.

"I think we racked up deficits that are going to be too much to overcome with just one storm system," said Mark Svoboda, director of the National Drought Mitigation Center in Lincoln, Nebraska.

"I would say it's way too early to say 'Yes, this drought is over,'" Svoboda said. "Does it put a dent in it? Yes, but we have a long ways to go."

The rain also brings danger because strong winds at the leading edge of the storms can topple trees and limbs that can kill and injure firefighters, he said.

In Mississippi, trees were reported downed Monday in nearly 20 counties across the state. Sustained winds of 30 to 40 mph with gusts of more than 50 mph were reported and more than 2 inches of rain fell in some areas.

Power outages peaked at more than 23,000 statewide in Mississippi. Powerlines downed by winds sparked grass fires in four counties, said Greg Flynn, a spokesman for the Mississippi Emergency Management Agency.

The storms moved across Alabama on Monday night and fell on Georgia during the overnight hours. High wind warnings were issued for mountainous areas in northern parts of Georgia.

In South Carolina, the stormy forecast was giving hope to firefighters battling a blaze in the northwest corner of the state. The South Carolina Forestry Commission hopes to contain the Pinnacle Mountain fire by the middle of next week.

More rain was expected Tuesday night and Wednesday morning in parts of Louisiana, Mississippi and Alabama.
