Jan 10 (Reuters) - Delta Air Lines ( DAL ) said on

Friday that departures and arrivals at its Hartsfield-Jackson

Atlanta hub have resumed after extreme winter weather forced the

closure of all five runways for more than two hours.

The carrier canceled approximately 700 flights across its

network on Friday and warned that additional adjustments to its

flight schedule are possible throughout the weekend.

Recovery efforts are ongoing at other airports throughout

the Southeast of the United States, the airline said.
