Low Clouds Impact Denver, San Diego, and Seattle Airports
The Federal Aviation Administration (FAA) said low cloud ceilings at Denver International Airport, San Diego
International Airport, and Seattle-Tacoma International Airport reduced the number of aircraft able to land safely in a given period, causing flight delays. The FAA noted that flight delays and cancellations also stem from air traffic volume, aircraft availability, and crew scheduling issues beyond weather. Not all recorded delays and cancellations were weather-related.
