Right now Cairo is in the middle of a sandstorm. A sandstorm is the desert's equivalent to a blizzard. Winds range from 20 miles an hour to 100. Visibility is sharply reduced. Walking is difficult. I actually walked right past my building because I was being buffeted by the wind so hard, and could not see the giant inscription of Jameel Hall. The palm trees sway gracefully, as though they are accustomed, but the deciduous trees struggle, branches cracking.
