What happened
AI-written · may contain mistakes. Written from the advisory text and weather only.
Cause: Air traffic control stopped departures because too many flights were leaving the airport at once. Skies were clear with light winds, so weather was not the stated problem.
The ground stop began at 17:12 UTC, initially set to end at 11:15 am PDT. At 18:04 UTC it was extended to 12:00 pm PDT, and departures were also held from four more air traffic control centers. The stop was still in effect after about an hour.
