At its peak, more than 18,000 customers lost power in Colorado Springs as falling tree limbs and blowing debris snapped lines and toppled poles causing hundreds of individual outages.
Linemen with Colorado Springs utilities began working to restore electric services early Monday, but the work may not be finished for another day or two.
The hardest hit areas were those with the highest concentration of overhead power lines like Old Colorado City, Ivywild and the Old North End.
"The biggest concern is probably the refrigerator," Old Colorado City resident Sarah Green said. "Thankfully I didn't go to the grocery store yet for this week. It's just, you know, being able to see around the house at night. We'll have candles and flashlights out I guess."
By late afternoon, crews had turned the power back on for nearly 10,000 of the 18,000 affected customers. As of 8 p.m. Monday night, about 5,900 customers were still without power, according to Colorado Springs Utilities.
In the meantime, crews are cautioning the public to be alert and stay away from fallen power lines. The City also encourages drivers to use caution when approaching dark traffic signals. They should be treated like four-way stops.
