Bad weather on Saturday sent 16 flights headed to Denver International Airport to the Colorado Springs Airport instead.

The flight were diverted because of microburst activity near DIA. Microbursts are caused by intense downdrafts within thunderstorms.

Eleven flights that landed in Colorado Springs earlier had flown on to Denver by 4:30 p.m., and five planes remained on the ground waiting to make the flight, said Heather Leonard, communications director at the Colorado Springs Airport. She said airlines took advantage of breaks in the weather to make the short flight to Denver.

The diverted flights included one from Spirit Airlines, three from Southwest, one from Frontier and 11 from Sky West, she said.

Passengers are advised to check with their airline about possible delays.
