Wind gusts as high as 55 miles per hour knocked over trees in Greeley and left hundreds of people without power in northern Colorado Saturday afternoon.

The Greeley Tribune reports that downed trees blocked multiple roads and downed power lines.

Wind gusts in Fort Collins and Loveland reached 60 miles per hour, the National Weather Service tweeted.

Winds are expected to become “light” by around 7 to 8 p.m., according to the NWS.

A strong cold front through the plains is to blame for the high winds.

Closer to Denver, where wind gusts still packed a punch even though they weren't quite as high, a viewer sent us photos of a tree branch shattering the back window of his car, which was parked near Washington Park.
