Trees blown down in several locations around the foothill communities adjacent to the Santa Ana and San Bernardino Mountains. An unladen 53 foot semi-tractor trailer was blown over the Lytle Creek Bridge on Interstate 15. Ash and soot from the burned areas in the were picked up by east winds gusting between 40 and 60 mph. Visibility was reduced across the valleys, coasts, and over the coastal waters out to San Clemente Island.
