McAllen, TX (KRGV) — A nationwide ground stop delayed multiple flights and canceled one Houston flight at the McAllen International Airport.

It comes after the Federal Aviation Administration grounded all flights nationwide Friday afternoon, causing hundreds of flights to be diverted. Officials cited "extraordinary circumstances" caused by communications problems at regional air traffic control centers, according to The Associated Press.

The FAA said it has no timeline for when things could be up and running again.

The Valley International Airport in Harlingen, Brownsville South Padre Island International Airport and McAllen International Airport issued travel advisories warning passengers of delays.

"We encourage all passengers to check directly with their airline for the latest flight status and travel updates," the McAllen International Airport said.

The advisories from the other airports have similar messages.
