Iraq has two seasons, winter and summer. The last few days it's been pretty warm, so I guess summer has arrived. With the winds shifting, the sun has been in and out, as the air carries more dust. I'm not sure why they call them sandstorms.
Dust storms seems closer to the reality. Imagine if every bit of dust that you have ever found under the bed or hiding on top of a cabinet was coming after you on a cloudy day at the beach; determined to swirl around you, make you feel the grit against your face, then continue on to the next victim.
It's clear near the ground, but the sky has a definite orange glow, and I expect we'll be cleaning it all off by Friday.
