Torrential Rain Floods Metro Denver Streets; 18K Lose Power

Fierce Thunderstorm Knocks Down Trees, Power Lines

A fierce thunderstorm walloped metro Denver Thursday afternoon, flooding streets, uprooting trees and knocking out power to 18,000 customers, officials said.

Xcel Energy spokesman Mark Stutz said crews were expected to restore power to most customers Thursday night. But some residents might not have electricity restored until Friday, he added.

Off and on Thursday, the National Weather Service issued flash flood warnings and advisories for communities across the metro region.

The Boulder Office of Emergency Management issued a flash flood warning until 9:15 p.m. for Fourmile Canyon west of Boulder, where a September fire burned 6,181 acres, stripping the canyon of trees and other vegetation.

The creek reached peak flow during the height of the storm, but its waters were receding Thursday night, OEM officials said.

Aurora police responded to several motorists who called 911 because their vehicles stalled in high water, police spokesman Detective Bob Friel said late Thursday afternoon.

Lightning struck a home in the 19500 block of East Batavia Drive and power lines were reported down at Victor Way and Center Avenue, he said.

Several officers stayed beyond their shifts to assist with the heavy 911 call volume generated by the storm, he said.

A severe thunderstorm warning created flight delays of up to 90 minutes at Denver International Airport Thursday evening, said DIA spokeswoman Laura Coale. She did not know the number of flights delayed.
