The latest updates on the storm's effect on some notable landmarks and attractions in and around downtown:

Centennial Olympic Park: Two of the "Hermes Towers" -- the 65-foot tall light towers that resemble giant Olympic torches -- were blown down at the park. An exhibit in the park -- "Red Bull Illume: Action and Adventure Sports Photography" -- also was affected by the storm, said Katy Pando, spokeswoman for the Georgia World Congress Center.

Georgia Pacific Building: Shattered windows could be seen on three sides of the Georgia Pacific building at Peachtree and Forsyth streets. Curtains in upper-floor windows were swaying in the wind. The area around the building was roped off for at least 10 yards because of broken glass dangling six stories up. Workers in hard hats were working to secure the building despite the danger.

Georgia World Congress Center: Officials said there was damage across the campus, including roof and water damage to the convention center. Katy Pando, spokeswoman for the GWCC, said the building was hit by both rainwater and water from the sprinkler system and damaged pipes inside the building.

She said there were some injuries, but none were serious. She did not know how many people were injured. "We're looking at bricks and mortar recovery, which is better than a life and limbs recovery," she said.

The staff at the GWCC plans to take the weekend to assess damage and hadn't determined whether the facility will be open Monday, Pando said. The GWCC, the fourth-largest convention center in the country, is one of Atlanta's biggest visitor venues, pumping millions of dollars into the city's economy every month.

Jimmy Carter Presidential Library and Museum: The Freedom Parkway attraction escaped damage from the storm even though condos and buildings just a short distance away were severely damaged. The center was pummeled by rain but there were no signs of flooding or building damage late Saturday morning.

Martin Luther King Jr. Center and Ebenezer Baptist Church: Officials connected to the historic Ebenezer Baptist Church said that tree limbs and other debris had blown in from other areas, but reported no damage. Rich Klima, park ranger with the National Parks Service, said the Martin Luther King Jr. National Historic Site escaped major damage. "We've looked around and we haven't found anything at the park. Our staff made it in here today and we're open for business."

Philips Arena: There was no discernible exterior damage, but officials canceled tonight's Winter Jam Spectacular. "The decision to cancel this evening's event was based on the estimated 18,000 people coming downtown during the clean-up of debris throughout the area," a statement form the arena said.

Grady Hospital: At least two historic buildings in the Grady Hospital complex suffered moderate damage and 17 of 18 buildings lost power, officials said. A few windows were blown out of the cafeteria in the main hospital where in-patients are treated, but the building retained power. Georgia Hall, the original home of the 115-year-old hospital, lost windows and a chimney, said Craig Tindall, Grady's interim chief operating officer, and there was some water damage inside. Three ambulances -- including Grady's only operating neonatal transport unit -- were out of commission Saturday because of storm damage. Hughes Spalding pediatric hospital, across the street from Grady's main building, lost a few windows, said Kevin McClelland, spokesman for Children's Healthcare of Atlanta, "but within an hour, we were accepting patients again."

St. Joseph's Mercy Clinic: Workers at the DeKalb Avenue facility, across the street from the Martin Luther King MARTA station, rushed to protect records and to shore up windows before another storm came that was expected Saturday afternoon. President Tom Andrews said a moving company had been summoned to remove critical medical records regarding indigent patients seen at the clinic, which is the headquarters for nine other clinics that are affiliated with St. Joseph's hospital.

Inside the clinic, portions of the roof had been torn off and water had saturated some computers and files, but nearby no evidence of the storm was evident. Maintenance worker Sam Wilcher noted that the ornamental cabbage and pansies planted just outside a shattered glass door went unscathed.

All five of the vans the clinic uses to transport patients were damaged, and the eight-ton heating and air conditioning unit on the roof had been picked up and tossed on its side. One piece of aluminum was propelled with such force that it cleanly penetrated a stucco wall. Andrews said he didn't know how the clinic would pay for repairs because it depends on grants, donations and Medicaid payments for its support.

Oakland Cemetery: At historic Oakland Cemetery, dozens of trees and old monuments were toppled by the storm. "We took a big hit," said Sam Reed, sexton, or caretaker, of the property.

He estimated that 50 or 60 old trees, including the oldest crepe myrtle, were down, many by the roots. Many more, including ancient magnolias, were damaged and may have to be removed. The 100-year-old ladies comfort station that was under renovation was split in two by a tree.

Winds also tossed headstones and obelisks. The 20-foot obelisk for the Winship family was toppled from its platform and had broken in half across a paved path. Metal from the nearby train tracks, paper from nearby offices and other trash littered the grounds. A shredded window blind was draped like a necklace around the marker for James L. Bell, a Confederate soldier who died in 1918.

"I've been here 10 years and I've seen storms come through here but never like this," said Reed. He was at the cemetery when the storm hit. "I'm not sure what it sounded like, but it looked like 'The Wizard of Oz.' Everything was flying around. I was going from my office to the bathroom. I didn't know where to hide."

Southern Automotive Warehouse: A chunk of the second floor of the large warehouse building on DeKalb Avenue was swept away by the storm. Across the street, fencing separating the street from the CSX railroad tracks had been flattened in several areas as if it had been run over.

Suntrust Building: Mangled blinds dangled out of broken windows on one side of the highrise building. The building's entrance area, which had been damaged by the storm, was boarded up Saturday morning.

Tabernacle: The staff of the Luckie Street concert hall arrived about 8:30 a.m. Saturday to assess the damage to the 98-year-old Atlanta landmark. "Most of the windows are blown out, the roof is severely damaged and there is lots of water damage inside," said Steve Woods, the building's electrician.

Outside the Tabernacle on Luckie Street, Woods reported seeing street lights and trees blown over in front of the building, cars damaged by falling debris in the venue's parking lots, and sidewalks and streets splattered with glass from blown out windows.

Woods and Eric Snoddy, building manager, are expecting major damage inside the building. "I know a water pipe broke inside," Snoddy said. "We're pretty much messed up. It's going to be awhile before we reopen. But it looks like we survived better than some places."

Ted's Montana Grill: A downtown Atlanta penthouse belonging to the owner, philanthropist and media mogul Ted Turner, suffered damage. As workers checked the residence's water, roof and window damage, employees of Ted's Montana Grill several floors below hurried to open in time for lunchtime Saturday. The penthouse and restaurant both occupy the Bona Allen Building on Luckie Street not far from CNN Center.

Turner was not in the residence at the time of the storm. The restaurant, though, had about 160 patrons Friday night when the winds tore through. "People immediately ran to the kitchen with debris blowing in the restaurant," said Ed Bazor, director of construction for Ted's. He said one person suffered a minor cut from shattered glass. Bazor said the building had at least $25,000 in damage.

Workers were patching windows Saturday so that the restaurant could reopen. The rest of the facility was in good shape, Bazor said, though the familiar bison-shaped sign will need to be replaced.

Westin Peachtree Plaza Hotel: The sidewalks below the landmark cylindrical high-rise are were littered with yellow insulation, broken glass and pieces of metal Saturday morning. Several windows were blown out.

Walton Building barbershop: The police officers and firefighters who get their hair cut at this historic snip shop have to find a new barber. The barbershop, facing Cone Street, suffered major damage. Large plate-glass windows were blown out and pieces of the drop ceiling sagged inside. A hunk of metal, blown from a building blocks away, rested on the sidewalk in front.

"There are apartments in this building, too," said Greg Alexander, a member of the building's management team. "No one got hurt, but the flower shop facing Walton Street got it real bad."
