A dust storm hit the US state of Colorado, and more than 100,000 homes and businesses in four other states lost power. Meteorologists described the unusual storm as a “dust bowl,” with winds reaching 100 kilometers per hour. Due to a severe storm, a truck overturned. “A storm that causes this much damage in such a short period of time would be unusual at any time of year. However, it is extremely unusual for this to occur in December “said Brian Barjenbruch, a National Weather Service meteorologist in the Nebraska Valley.
