DENVER - Seventeen flights were diverted from Denver International Airport to other airports because of microburst activity on Friday night, DIA spokesman Heath Montgomery said.
About 13 flights were diverted to Colorado Springs Municipal Airport, Montgomery said.
Microbursts occur when thunderstorm conditions cause powerful downdrafts.
Montgomery said at 7:35 p.m. that the microburst activity had been happening for the past 30 to 45 minutes and was expected to end at about 8 p.m.
7NEWS Meteorologist Matt Makens said at 9:35 p.m. the microburst threat at DIA was much lower.
Montgomery said the diverted flights would refuel in Colorado Springs and then return to DIA.
