Hartsfield-Jackson Airport lacks the snow-clearing equipment common in northern airports, which compounds the challenges of severe weather. Delays and cancellations are expected to continue through the day, even as temperatures in Atlanta may rise slightly above freezing later in the afternoon.

Atlanta-based Delta Air Lines has canceled more than 300 flights Saturday as the fallout of its struggles during a Friday winter storm at its Atlanta hub continued into a second day. The storm disruptions were compounded by an aborted takeoff of a Delta plane with passengers evacuating via emergency slides onto a snowy runway Friday morning.
