School districts in Denver generally announce closures through their official websites, automated phone calls, local TV, and radio stations, with most decisions made by the superintendent in the early morning hours, typically by 5:00 AM on storm days. Two-hour delays and remote-learning days are sometimes used in Denver as alternatives to a full closure when conditions are borderline.
