"Please know that while conditions are improving and roads are drying, the playa is still muddy and may be difficult to navigate in some neighborhoods and down certain streets," Burning Man organizers wrote in a statement. "Avoid the 5:30 radial street, stay on hard-packed roads and out of standing water."

Organizers are asking burners to consider holding off on leaving until Tuesday to help with the traffic crush. Many may wait anyway; because of weather, the burning of the "man" was delayed, too. It's scheduled to take place at 9 p.m. Monday. For more information about leaving Burning Man, visit the organizers' site here.

Sept. 4, 9:20 a.m. The "exodus" from Burning Man has been delayed again, Burning Man organizers announced Monday. Although they'd hoped to get the mass departure from Black Rock City underway by Monday morning, it now appears that noon will be the earliest time roads may be safe for 70,000 people to leave.

"Gate road remains a bit too muddy and there is still too much standing water along it for large numbers of vehicles to safely navigate out of the event this morning, but it is drying up," organizers wrote on the "Wet Playa Survival Guide" page. "We anticipate that Exodus will be able to officially begin around noon today."

Organizers also asked that people "do not walk out of Black Rock City to County Road 34 at this time." They expect that more information about departure will be available in the next few hours.

Sept. 3, 9:50 p.m. Burning Man organizers announced that people attending will be able to start leaving Black Rock City on Monday morning, and that they would inform festival-goers by 9 a.m. of their decision.

Organizers asked that as exodus begins, people still avoid Gate Road, which remained unusable due to the mud. 

"We have created alternative routes that if used on Monday you will be flagged to the best area to drive across," the statement said.
