Wider weather episode

Due to ongoing construction in and around the Grand Junction Regional Airport, days with particularly strong winds and/or outflows from nearby thunderstorms can trigger localized dust storms that reduce the visibility to less than 1 mile. Typically these events last less than 20 minutes. However, on this day the reduction in visibility was to below 1/4 mile and lasted for approximately 2 hours.
