A spring rainstorm packed with hail raced across the Denver metro area today, halting traffic at Denver International Airport.
The storm created heavy downward winds called microbursts that grounded departing planes and forced arriving flights to stay airborne in a holding pattern.
Frontier Airlines spokesman Joe Hodas says about ten flights were delayed for up to 25 minutes. It was unclear how many other flights were affected.
Seattle-based FAA spokesman Allen Kenitzer says airport operations were halted for up to 45 minutes late this morning.
The National Weather Service says small hail carpeted several areas from Denver to the foothills northwest of the city.
