Los Angeles fire officials say they're ready for "Carmageddon."
Battalion Chief Chuck Butler says more than two dozen fire engines and ambulances have been staged in neighborhoods where they'll be able to move quickly even if there's gridlock from the weekend shutdown of a 10-mile stretch of Interstate 405.
Six aircraft also will be available, including air ambulances.
Butler says Mother Nature will be working with firefighters over the weekend because of predicted higher humidity that will put a damper on potential wildfires.
Beginning Friday night, police and traffic engineers also will be on standby to respond to emergencies as the freeway shuts down for 53 hours.
