As the storm clouds approach, a bright orange "fog bank" appears ahead of the storm. This is the sandstorm, which boils out in front of the rainclouds. The fierce winds pick up the fine Sahara sand and throw it hundreds of feet into the air, creating a massive orange cloud of dust that gradually gets bigger and bigger as it approaches. As you watch it coming, the air is still and close. Suddenly, the sandstorm hits, and the winds increase to gale force knocking down trees and branches and carrying away anything light with them. The dust sandblasts your face and skin, and the day becomes dark and gloomy. Sometimes there is so much sand in the air that the sky becomes black as night. The sandstorm may last anywhere from 5 minutes to an hour. The temperature drops dramatically, often as much as 30 degrees fahrenheit in the space of five minutes. After the sandstorm passes, the rain begins. Huge thunderclouds unleash their reservoirs of water, and torrents of rain begin lashing the ground. Within an hour, an inch or two or rain may fall. After the storm all is cool and still, and the smell of the rain settling the dust perfumes the air. "
dust storm with it, just a lot of wind. That night was really cool. We haven't seen any rain in Tera since May 13, and the rainy season hasn't officially started yet, but some parts of the country have already been blessed with good first rains. Once the rains get going, they settle the dust down, and the dust storms don't blow any more.
