High winds swept across Boulder County today, toppling trees and power lines.
The National Center for Atmospheric Research's Mesa lab recorded gusts of up to 79 mph and sustained winds as high as 37.8 mph, while the National Wind Technology Center just south of Boulder recorded a gust of 71.9 mph.
Boulder County is under a high wind warning until 5 p.m. today.
"The presence of a mountain wave and a large cross mountain pressure gradient will continue to produce strong and very gust Chinook winds over and hear the Front Range foothills today," the National Weather Service reported. "Winds will weaken late this afternoon and through the evening although gusts to around 50 mph will still be possible in the foothills."
Boulder County sheriff's Division Chief Heid Prentup said that the winds had knocked down trees and telephone lines across the county, leading to traffic hazards. She also said that one driver was injured when a sign that had fallen down crashed into the car's window.
There were also several reports of downed trees within the city of Boulder, including one tree near Naropa University on Arapahoe Avenue that crashed into a house. Boulder police spokeswoman Shannon Cordingly said nobody was injured, but there was damage to the roof and the fence.
Cordingly said residents should take precautions to avoid safety hazards with the high winds.
"If the forecast calls for high winds, gather loose objects and safely store them indoors," Cordingly said. "Objects left outside in wind storms can pose two dangers. They can either become projectiles and potentially injure people and property, or the objects themselves can be lost, damaged or ruined."
Cordingly also said drivers should watch for debris while driving and anyone who sees downed power lines should call 303-441-3333.
In Longmont, high winds delayed trash pickup in the city.
