6:33 p.m.: Tollgate Creek in southeast Aurora also was running high after steady rainfall since Wednesday.

Twitter user John Gillespie shared a video of the creek that showed it had topped its banks and was overflowing onto the ground nearby.

Gillespie said the video showed the flow through a purposeful spillway at East Mexico Avenue between Chambers and Buckley roads. The creek travels north to join Highline Canal north of Alameda.

He said he did see some ground eroding into the creek, “but I believe the bordering terrains were designed to accommodate these rare occasions of swelling creek spills.  I don’t believe these have caused any concerning erosion over the 45 years I’ve lived nearby.”

6:21 p.m.: Since the start of the stormy weather on Wednesday, 2.65 inches of rainfall has been measured as of 6 p.m. Thursday at Denver International Airport.

That figure represents 18.3% of Denver’s annual average precipitation — 14.48 inches — according to the National Weather Service.

5:24 p.m.: Cherry Creek has flooded along downtown Denver, according to multiple reports. A Denver Office of Emergency Management tweet shows a photo of the creek at 6th Avenue and Speer Boulevard flooded nearly up to the bridge of 6th Avenue.

Other photos posted on Twitter show the Cherry Creek Trail flooded near Confluence Park where the creek meets the South Platte River.

Denver Parks and Recreation is asking trail users to avoid the trail until Friday morning, urging users to use caution on other trails and to turn around when encountering flooded areas.

The total so far for this storm is 2.31 inches, and the rain is far from over. The normal annual average is 14.48 inches of precipitation.

The rain will continue pretty heavily over the next couple hours, followed by a short break before the storms build back in later Thursday evening and overnight into Friday morning.

2:48 p.m.: A landspout is possible in the area near Ovid and Sedgwick until 3:15 p.m. according to a special weather statement. It said hail is not expected.

2:42 p.m.: Delays for flights in and out of Denver International Airport continued to rise Thursday afternoon as heavy rain drenched the area.

2:11 p.m.: Heavy rains were causing damage around the metro area on Thursday afternoon.

In Denver’s Capitol Hill, a retaining wall in an alley between the 800 blocks of Sherman and Grant streets collapsed after hours of rain.

2:09 p.m.: A portion of Lake View Road in Cherry Creek State Park is closed after heavy rainfall flooded and damaged part of the road, Colorado Parks and Wildlife reported. The closure is on the southeast side of the state park near the dog park, but CPW officials said the dog park and all park entrances are still open.

Photos of the damage show a flooded roadway, and water can also be seen eroding the dirt under the road and the pavement itself.

1:59 p.m.: Colorado Springs fire crews safely rescued a man and his dog early Thursday morning from a flooded sandbank on Monument Creek. The swift water rescue happened near 200 W. Bijou Street south of Monument Valley Park.

The National Weather Service has issued a tornado watch for eastern Colorado.

The watch issued at 11:20 a.m. covers Cheyenne, Kiowa, Kit Carson and Yuma counties, effective through 6 p.m., along with parts of Kansas and Nebraska, weather service meteorologists said.

On Thursday morning, a tornado may have formed in eastern Colorado near the border with Kansas and skirted the town of Arapahoe in Cheyenne County — which prompted a weather service warning that since has been lifted.

It was unclear whether this tornado touched down on open plains, said weather service meteorologist Kyle Knight, posted in Goodland, Kansas.

“We have not received any reports. If there was a tornado, it would be rain-wrapped, so we’ll have to wait to see if it hit anything. There’s a chance it may have formed, touched down and hit a field, and went back up.”

The weather service radar showed a vortex about five to 10 miles southwest of Arapahoe, population 102, shortly before 11 a.m.

Damage from a tornado depends on the strength and size, and tornadoes in Colorado typically are weaker than those on the Great Plains and the southeastern United States, said Bruno Rodriguez, a weather service meteorologist based in Boulder. “Obviously, if it does reach an urban area, it can cause extensive damage.”

On Wednesday, the weather service issued tornado watches in Colorado as thunderstorms rolled off the mountains onto the high plains. Tornadoes close to Colorado’s urban Front Range appeared less likely Thursday, meteorologists said. A cloudy gray mass of thunderstorms dropping rain in metro Denver and Colorado Springs has raised risks of flooding. The weather service has issued a flood watch effective through Friday.
