Muddy roads flooded by a summer storm that left tens of thousands of partygoers had dried up enough by Monday afternoon to allow them to begin their exodus from the northern Nevada desert.

Event organizers said they started to let traffic flow out of the main road around 2 p.m. local time 鈥� even as they continued urging attendees to delay their exit to help ease traffic Monday. About two hours after the mass departure began, organizers estimated a wait time of about five hours.

The annual gathering, which launched on a San Francisco beach in 1986, attracts nearly 80,000 artists, musicians and activists for a mix of wilderness camping and avant-garde performances

Organizers also asked attendees not to walk out of the Black Rock Desert about 110 miles (177 kilometers) north of Reno as others had done throughout the weekend, including DJ Diplo and comedian Chris Rock. They didn鈥檛 specify why.

The festival had been closed to vehicles after more than a half-inch (1.3 centimeters) of rain fell Friday, causing flooding and foot-deep mud.

The road closures came just before the first of two ceremonial fires signaling an end to the festival was scheduled to begin Saturday night. The event traditionally culminates with the burning of a large wooden effigy shaped like a man and a wood temple structure during the final two nights, but the fires were postponed as authorities worked to reopen exit routes by the end of the Labor Day weekend.

鈥淭he Man鈥� was torched Monday night while the temple is set to go up in flames 8 p.m. Tuesday.

The National Weather Service in Reno said some light rain showers could pass through Tuesday morning. The event began Aug. 27 and had been scheduled to end Monday morning, with attendees packing up and cleaning up after themselves.

鈥淲e are a little bit dirty and muddy, but spirits are high. The party still going,鈥� said Scott London, a Southern California photographer, adding that the travel limitations offered 鈥渁 view of Burning Man that a lot of us don鈥檛 get to see.鈥�

are part of the event鈥檚 recent history: Dust storms forced organizers to temporarily close entrances , and the event was twice canceled altogether during the pandemic.

At least one fatality has been reported, but organizers said the death of a man in his 40s wasn鈥檛 weather-related. The sheriff of nearby Pershing County said he was investigating but has not identified the man or a cause of death.

President Joe Biden told reporters in Delaware on Sunday that he was aware of the situation at Burning Man, including the death, and the White House was in touch with local authorities.

The event is remote on the best of days and emphasizes self-sufficiency. Amid the flooding, revelers were urged to conserve their food and water, and most remained hunkered down at the site.

Some attendees, however, managed to walk several miles to the nearest town or catch a ride there.

Diplo, whose real name is Thomas Wesley Pentz, posted a video to Instagram on Saturday evening showing him and Rock riding in the back of a fan鈥檚 pickup truck. He said they had walked 6 miles through the mud before hitching a ride.

鈥淚 legit walked the side of the road for hours with my thumb out,鈥� Diplo wrote.

Cindy Bishop and three of her friends managed to drive their rented RV out of the festival at dawn on Monday when, Bishop said, the main road wasn鈥檛 being guarded.

She said they were happy to make it out after driving toward the exit 鈥� and getting stuck several times 鈥� over the course of two days.

But Bishop, who traveled from Boston for her second Burning Man, said spirits were still high at the festival when they had left. Most people she spoke with said they planned to stay for the ceremonial burns.

鈥淭he spirit in there,鈥� she said, 鈥渨as really like, 鈥榃e鈥檙e going to take care of each other and make the best of it.鈥欌��

Rebecca Barger, a photographer from Philadelphia, arrived at her first Burning Man on Aug. 26 and was determined to stick it out through the end.

鈥淓veryone has just adapted, sharing RVs for sleeping, offering food and coffee,鈥� Barger said. 鈥淚 danced in foot-deep clay for hours to incredible DJs.鈥�
