The flash flood warning for west-central El Paso County was cancelled about 10:45 a.m. by the National Weather Service, prompting U.S. Highway 24 to be reopened by the Colorado Department of Transportation.
Transportation spokesman Bob Wilson said there was heavy rainfall between Cascade and Cave of the Winds, but no flooding had been reported Wednesday.
"The rain has been heavy on the culverts, but we've had no reports of water flowing onto the roads, or rock slides," Wilson said, adding the department was prepared to close the highway if weather conditions worsened or a warning was reissued.
Colorado Springs Fire Department crews mobilized to the western part of the city, as unimproved waterways were of most concern for overflows.
"The Heavy Rescue Unit from station 17 and an engine from station 19 have moved to the west side and are prepared for any emergency," spokeswoman Sunny Smaldino said. "Our city's infrastructure can handle the rising waters in the improved and newer waterways, but the western end of the city has ditches and creek beds that overflow easily."
Colorado Springs City crews were also monitoring possible flood points around the western part of the city along with fire crews, city spokeswoman Kim Melchor said.
The National Weather Service reported streams coming out of the burn scar were running at or near bankful and any additional rain could cause these streams to overflow. The most susceptible areas for flash flooding will be Williams Canyon, Waldo Canyon and Camp Creek, according to the weather service.
"Rain has saturated the ground over the Waldo Canyon burn scar area this morning," the weather service stated. "Additional showers and thunderstorms capable of producing locally heavy rain over a short period of time will be possible from late this morning through early this evening."
Colorado Springs, Cascade, Chipita Park and Manitou Springs could experience flooding due to runoff from excessive rainfall.
The Black Forest burn scar could also see heavy rainfall Wednesday.
A flash flood watch was issued by the weather service until 9 p.m. for El Paso and Teller counties and Rampart Range.
An urban and small stream flood advisory for west-central El Paso County, including the Waldo Canyon burn scar, was initially issued by the weather service until 10:30 a.m.
Rain gauges in the burn scar indicated that up to two-tenths of an inch of rain had fallen since 7 a.m. and the radar shows more precipitation heading toward Waldo Canyon, with more possible rainfall amounts of up to two or three-tenths of an inch by 9 a.m.
"Just a small amount of rainfall on a burn scar can lead to flash flooding," the weather service stated. "Water that is normally absorbed by the soils and vegetation runs off almost instantly."
Scattered to numerous showers and scattere thunderstorms are expected into Wednesday evening. Other storm threats will include could-to-ground lightning and wind gusts of up to 45 mph, while stronger storms could produce small hail.
Cloudy skies and a high near 68 degrees are in the forecast for the rest of the day, with temperatures dipping to the low 50s by the evening.
