DENVER (AP) -- A tornado briefly touched down over the east runways of Denver International Airport, where thousands of people took shelter in bathrooms and stairwells until a tornado warning passed.
There have been no reports of injuries or damage.
Weather service meteorologist Kyle Fredin says a 97 mph gust was measured at the airport before communications with instruments there were briefly knocked out Tuesday.
Dark clouds blanketed parts of the horizon over the plains to the east.
Airport officials say some flights headed to Denver were diverted elsewhere.
Television coverage showed the airport's normally busy terminal was empty during the tornado warning.
As the storm passed, police briefly blocked traffic from Interstate 70 to Pena Boulevard, which leads to the airport.
