Mystery Dust Covers Glendora Neighborhoods

Glendora residents awoke to an usual sight Wednesday morning – a layer of dust caked onto numerous cars, driveways and sidewalks.

Residents in various parts of Glendora, including Westridge Avenue, Mauna Loa, and N. Glendora Avenue reported the mystery ash.

The sight of the mystery dust blanketing cars and driveways of entire streets confused even longtime residents of Glendora.

Glendora Public Works received several reports from residents complaining about the dust, although city officials did not have an immediate explanation.

Director Dave Davies said South Coast Air Quality Management District is looking into the case.

Strong Santa Ana winds descended upon parts of Los Angeles County Wednesday morning, although the full force of the winds had little impact on the San Gabriel Valley, said Weather Specialist Bonnie Bartling.

Bartling said it was possible the mountain winds – peaking at 70 mph in some areas – may have pushed dust into the foothill region of the San Gabriel Valley, especially in areas where brush fires are common. However, AQMD has yet to confirm heavy winds as the source.
