The picture in the post a few days ago is the aftermath. This one is the real deal;
a dust storm on a fifty kilometre front heading directly towards the camera.

It was so vast one shot could not get the whole front in the frame.

It was very eerie. Absolute silence and stillness as the storm approached.

The eerie atmosphere continued until the wall of dust was only a hundred metres or so away, then the howling, deafening wind engulfed everything with flying sand. Visibility was zero.

I didn’t get my car door shut in time. Everything was sandblasted, my car was buffetted relentlessly and the wind went on for what seemed like hours.
