Four Colorado resort cities, including Durango, have canceled their Fourth of July fireworks displays due to the recent hot, dry weather.

Steamboat Springs Fire Rescue Chief Mel Stewart says that city’s display was canceled after officials determined the show could spark a wildfire.

Little precipitation and hot weather over the past month also led the Aspen Chamber Resort Association to cancel its show. Aspen Deputy Fire Chief says the decision was made after noting the dry vegetation in the display area and in consultation with neighboring fire districts.

Canon City’s display was canceled due to a shortage of federally licensed people to ignite large displays. Hank Holloway, chairman of the Fremont County Fireworks Committee, says the show will be rescheduled for 9 p.m. on New Year’s Eve.

Durango canceled its show after the Lightner Creek Fire broke out Wednesday.

Scot Davis of DFPD said that the issue had been on the radar for a couple weeks and became more urgent earlier this week when La Plata County announced Stage 1 fire restrictions.

“Honestly, it was fairly imminent,” Davis said. “We just needed a time to discuss.”

Several factors led to the postponement, Davis said. The Lightner Creek Fire has used the majority of the fire department’s resources, and the timeline for containment is uncertain. The department was also concerned with future weather patterns, as forecasts predict multiple hot, dry and windy days leading up to Tuesday.

Colorado had a larger number of cancellations in 2012 and 2013.
