I hadn't heard that your area was expecting that sort of violent
weather. Was it unexpected?

Just google "haboob"
It's an unbelievably *GIANT* duststorm.
Do an image search for "haboob" and
see some unbelievable pics.

Here's a sneak preview for you:

Yes, have seen one in the Sahara but didn't know they were called
that. The sand manages to get into everything

I've never experienced a dust storm here in NH, so this might be a stupid question, but, where does the dust come from? Are they only in areas near a desert? How far from a desert can this dust travel?

I saw video of the storm/wind/dust on The Weather Channel this
morning. I certainly hope they called that a haboob. I'm always
amazed when I see one. They are so menacing looking like something
from a sci-fi movie. I'm glad you suffered no damage. Did you get
your car under cover to save the finish from the sand?
take care

Arizona is mostly covered by dirt and sand in undeveloped areas
since it's so dry and hot (take a look at satellite phots and
compare the brown to the green). Unlike other states where there's
various types of native ground cover to secure the dirt to the
ground. Lose dirt and sand make for dust storms during high winds.
And high winds often precede a rain storm rolling in.
