A second ground stop hit Denver International Airport on Wednesday afternoon due to thunderstorms, according to the Federal Aviation Administration’s National Airspace System Status web page.

“Departures to Denver International are grounded due to thunderstorms,” the FAA stated. Los Angeles, Salt Lake City, Kansas City, Albuquerque, and Minneapolis were listed as inbound airports affected.

FlightAware.com, a air travel monitor, reported 233 delays and 85 cancelled flights by midday at DIA.

The FAA issued DIA’s first ground stop Wednesday morning due to low visibility, according to airport spokesperson Ashley Forest.

Just after 10 a.m., the ground stop was lifted.

There could be a ripple effect, causing some flights throughout the day to be delayed, according to Forest. DIA advises passengers to check with their airline for up-to-date flight status.

As of 10:40 a.m., Wednesday, 52 flights were cancelled into or out of DIA and 165 flights were delayed into or out of DIA, according to flight tracking website FlightAware.

Southwest Airlines has the highest number of delayed flights, with 56 flights, 10% of their total, delayed. Southwest had cancelled 49 of their flights, or 8% of their total, as of 10:40 a.m.

United Airlines followed shortly behind in delays with 53 delayed flights, or 9% of their total. As of 10:40 a.m., they only had one cancelled flight.

“We’re seeing lots of delays today due to this weather,” DIA said on Twitter. “Check with your airline for up-to-date flight status. Be safe out there!”
