The ground delay, which is separate from the outage, is related to "low ceilings" for departures, tied to poor weather conditions.

The Federal Aviation Administration says it's taking immediate steps to alleviate the delays at Newark Liberty International Airport​ that began more than a week ago​.

Radar screens that monitor Newark Liberty International Airport in New Jersey went completely black for about 90 seconds early Friday morning, according to a new report from ABC News. The outage comes after an identical problem last week when air traffic control screens for the same airport went dark for about 60-90 seconds.
