A significant windstorm hit Colorado’s Front Range on Wednesday, resulting in widespread power outages and disruptions across the region. Nearly 200,000 utility customers were affected as schools closed and multiple flights were delayed at Denver International Airport (DIA).
Windstorm Details
Wind gusts measured up to 109 mph at the National Center for Atmospheric Research’s Mesa Laboratory in Boulder. Other notable gusts included:
- 102 mph at Rocky Flats National Wildlife Refuge
- 95 mph near Fourmile Canyon, Boulder County
- 83 mph at Rocky Mountain Metropolitan Airport in Broomfield
- 47 mph at Centennial Airport
- 32 mph at DIA
- 52 mph at Northern Colorado Regional Airport in Loveland
- 35 mph at Colorado Springs Airport
According to Robert Koopmeiners, a meteorologist with the National Weather Service, Colorado typically experiences these windstorms during fall and winter. However, the intensity of this storm surprised many, as the last similar event occurred four years ago.
Previous Windstorm Impact
In December 2021, a comparable storm contributed to the Marshall fire, which tragically claimed two lives and destroyed over 1,000 homes. An investigation found that downed power lines from Xcel Energy ignited the fire, though the company denies responsibility.
Power Outages and School Closures
Xcel Energy proactively disconnected power to 50,000 customers in various counties, including Boulder, Clear Creek, and Jefferson, to prevent wildfire risks. As of 6:30 p.m. on Wednesday, there were 176 unplanned outages affecting over 113,000 customers across Adams, Denver, Jefferson, and more.
Schools also took precautionary measures, with institutions like the University of Colorado and Red Rocks Community College canceling classes. Jeffco Public Schools announced the cancellations late Tuesday, reflecting the evolving situation.
Transportation Disruptions
The storm severely impacted Colorado’s transportation systems. The Colorado Department of Transportation closed several highways, particularly in the foothills. Notable closures included:
- U.S. 287 between Larimer County and Wyoming
- Colorado 93 between Colorado 128 and 72
- U.S. 36 north from Boulder to Lyons
Additionally, the Regional Transportation District halted light rail services along the W-Line due to planned power cuts, substituting bus services instead. The Federal Aviation Administration imposed a ground delay at DIA, resulting in average flight delays of 74 minutes and affecting over 400 flights.
Future Weather Forecast
Following the storm, weather in the Denver area is expected to calm on Thursday, with a forecasted high of 47 degrees and light winds. However, another storm system is anticipated to hit on Friday, potentially bringing even stronger winds and warmer temperatures, with Denver possibly reaching a record high of 68 degrees.
As the situation develops, Xcel Energy warns that additional power cuts may be necessary during the upcoming storm.
