Residents reported hearing an explosion near a busy Midtown intersection Monday night, prompting a response from Atlanta Fire Rescue crews who later found and extinguished a small underground fire that knocked out power to thousands of customers.

Atlanta Fire Rescue said crews were called to the area of 11th Street and Crescent Avenue around 8 p.m. after witnesses reported hearing what sounded like an explosion. Firefighters located a small underground fire, which was quickly put out. 

Atlanta police blocked off the area as a safety precaution, and officials urged the public to avoid the intersection while crews worked. No injuries were reported. 

A Georgia Power spokesperson said it was an equipment failure that caused the outage affecting about 4,000 customers in Midtown Atlanta. The company said power was restored to most customers early Tuesday morning. Crews are still on scene to complete final repairs.

Less than 10 customers remain without power, according to the Georgia Power spokesperson, and service is expected to be fully restored by noon Tuesday. The utility company emphasized the outage was not related to the winter storm.

A day after the massive ice storm passed through Georgia, crews at the Atlanta airport are working to get business back to normal.

On Sunday, nearly 1,200 flights arriving or departing from Hartsfield-Jackson Atlanta International Airport were canceled. Over 500 were delayed. At one point, the airport issued a ground delay that averaged around 117 minutes for all flights.

Monday’s situation at the airport was much calmer, despite below-freezing temperatures that caused the weekend’s rainfall to turn back into ice.

According to Flight Aware, 203 flights had been canceled — the majority of which were arrivals. The airport also reported 189 delayed flights as of Monday morning.

Across the country, over 4,600 flights were canceled. Atlanta-based Delta Air Lines reported the fourth-most cancellations with 368, or 11% of flights.

In a release, Delta said its teams plan to resume operations as long as the weather permits. Customers should check on their flight status online or through their airline’s app.

Many airlines are still offering travel waivers, allowing customers to change their plans at no additional cost.
