It remains unclear at this moment exactly what prompted the Federal Aviation Administration to issue a nationwide ground stop. The agency is citing “extraordinary circumstances” and “reasons of safety,” with Markwayne Mullin, the secretary of homeland security, blaming a telecommunication outage.

“This isn’t going to just be resolved and turned around within the hour,” he said. “This is going to take some time.”

The County of Humboldt confirmed on social media that the order includes our local airports:

Heads up, Humboldt! The Federal Aviation Administration (FAA) has issued a nationwide ground stop for all departing flights, including those at the California Redwood Coast-Humboldt County Airport (ACV). At this time, we do not know when normal flight operations will resume.

If you are traveling or have plans to travel soon, please check your airline’s app or website for the latest flight information before heading to the airport.
