The Federal Aviation Administration imposed a ground stop at 4:32 p.m. local time on Saturday, August 29, 2026, halting all flights destined for Denver International Airport. The directive was issued in response to thunderstorms detected in the Denver area.
The ground stop affects departures from six Air Route Traffic Control Centers: Los Angeles (ZLA), Salt Lake City (ZLC), Denver (ZDV), Kansas City (ZKC), Albuquerque (ZAB), and Minneapolis (ZMP). The stoppage was initially set to last until 6 p.m. but carries a 30% to 60% chance of extension depending on weather conditions.
Weather Conditions Causing Flight Halt
Weather activity includes a marginal risk of severe storms
in portions of Colorado, with potential for high winds and hail primarily in mountainous areas and north of Interstate 70. The Denver metropolitan area and northeast Colorado face the threat of severe weather into the evening hours, prompting precautionary flight restrictions.
Impact on Flights and Travelers
The ground stop has led to delays for flights arriving at Denver International Airport, affecting both inbound and outbound traffic due to the directive on departures from multiple ARTCC zones. Passengers should expect continued delays during and possibly beyond the ground stop period as flights remain grounded until conditions improve.
