At the Georgia World Congress Center, the scars are still visible from the March 14 tornado that ripped through Atlanta: Missing ceiling tiles, plywood covering empty window frames and gaping holes in the roof.

The storm left eight of the GWCC's 12 exhibit halls unavailable.

Still, GWCC officials are confident that, except for possibly one convention starting Sunday, no multi-day events will have to take their show — and their money — elsewhere.

"We're confident that we're going to be able to work with all of our shows," GWCC spokeswoman Katy Pando said Monday after a media tour of the mammoth venue.

Monday, the International Window Coverings Expo and National Propane Gas Association began to move their shows into undamaged sections of the 1.4 million-square foot monolith. The two events, with a combined attendance of 14,000, will create an estimated economic impact of $14 million, according to the Atlanta Convention & Visitors Bureau. The former begins Wednesday, the latter Saturday.

Only the Clinical Laboratory Management Association, scheduled to start Sunday and bring in about 6,000 attendees for two nights, has been canceled. The GWCC and ACVB are trying to re-schedule the event. Several single-day upcoming events, such as the Christian College & Career Expo, have been postponed or canceled. The GWCC did not provide a count of those events, as it is still determining how many will have to be altered.

Monday, construction workers were fixing the corrugated steel roof that the tornado ripped open in Building B. Pando said that the GWCC expects to receive a timeline this week for when the damaged areas of the convention hall can come back online, including an estimate of the repair cost.

Georgia Insurance Commissioner John Oxendine has estimated that repair costs will exceed $100 million.

Elsewhere in Atlanta, residents were trying to start repair projects of their own.

The Federal Emergency Management Agency said that 214 individuals applied for assistance Friday and Saturday. FEMA offices were closed Sunday for Easter. Of those who sought help, 198 had properties in Fulton County. There were 12 applicants in DeKalb.

Anyone who sustained losses from the storms March 14-16 in Fulton or DeKalb, as well as Bartow, Burke, Floyd, Jefferson and Polk counties, is eligible. FEMA grants can cover losses not covered by insurance, but the maximum aid that a single applicant can receive is $28,800.

If uninsured losses are greater than that, individuals can apply for a low-interest loan from the U.S. Small Business Administration, which offers loans to homeowners, renters and businesses to repair or replace damaged property. The U.S. SBA, a federal government agency, offers loans as low as 2.75 percent for up to $40,000 for personal property and $200,000 for real estate. The maximum for business loans is $1.5 million.

"We always encourage everyone to use their existing insurance," said FEMA spokesman William C. Lindsey. "If they're underinsured (or uninsured), then with their registration with FEMA we would look at each individual's circumstance."

The man believed to be the only possible casualty of the March 14 tornado has been identified as Gregory Lee, 45, of Atlanta.

The Fulton County Medical Examiner's Office said he was identified by a family member. Lee was found Saturday by workers clearing rubble from a building at 382 Decatur Street that was damaged by the tornado. As cause of death has not been determined, it is not known if he actually died as a result of the tornado.
