From New York Post (caution: tabloid):
A powerful dust storm wreaked havoc on Nevada’s annual Burning Man festival over the weekend, tossing around early attendees’ campsites and trapping incoming Burners in up to eight hours of stop-and-go traffic.
The National Weather Service issued warnings about the storm in advance, noting it would bring in a fast-moving “wall of blowing dust.” But by Saturday, Burners were already descending on Black Rock City.
