DENVER — The National Weather Service (NWS) in Boulder issued Flash Flood Warnings that covered parts of northern Colorado.
One warning applied to an area that includes Wellington, Timnath and Windsor.
Residents were told to move to higher ground immediately and avoid walking or driving through flood waters.
The warning is expired at 10:30 p.m.
Another was issued for an area that includes Johnstown and Milliken. It was in effect until 11 p.m.
Flash Flood Warnings were also issued in less populated areas of Colorado.
One was in effect in Grand County in the East Troublesome Fire burn scar. It expired at 8:45 p.m.
A Flash Flood Warning was issued in Elbert County east of Kiowa. It stayed in effect until 9:30 p.m.
A warning that expired at 7 p.m. was issued for the Cameron Peak Fire burn scar in Larimer County.
Another one was issued for Park County. It expired at 7:30 p.m.
The flooding follows severe weather in metro Denver Sunday afternoon. Severe Thunderstorm Warnings were issued for southern parts of the metro area including Parker, Lone Tree and Larkspur. They expired at 4:15 p.m.
Parker Police said Bradbury Ranch Road north of Mainstreet between Independence Drive and McClellan Drive will be closed indefinitely after the road, which runs over a bridge, collapsed.
Elsewhere in Douglas County, Flintwood Road is closed just north of Singing Hills Road due to road damage. The Douglas County Sheriff's Office said the fear is that the road may collapse due to water washing out underneath. It's not clear when the road will be repaired and reopened.
The storm impacted operations at Denver International Airport, which was under a ground delay. Hundreds of flights were delayed, and nine were canceled.
Lightning was also a threat Sunday. South Metro Fire Rescue responded to a fire at a home on Valleybrook Circle near Highlands Ranch in unincorporated Douglas County that was struck by lightning. South Metro said that fire is under control and no one at the home was injured.
More storms are likely Monday and Tuesday, with at least some severe weather risk both days.
