The low cloud ceilings are reducing the number of aircraft able to land safely, particularly at Denver, San Diego, and Seattle airports. This has led to significant disruptions for passengers, with nearly 1,900 flights delayed and over 50 canceled across the U.S. Travelers may face extended wait times, missed connections, and potential rebooking challenges. The situation is dynamic, with conditions subject to rapid changes, especially at affected airports. Passengers are encouraged to plan for delays and monitor updates closely.
