Sandstorm weather cycles in hot biomes like desert, and mesa. A common sandstorm would darken the skies and lower visibility like a rainstorm, but tint everything a light brown hue. A severe sandstorm would darken the skies further like a thunderstorm,and reduce visibility more thn a common sandstorm would. It would also tint everything with a dark brown hue, and have lightning. sand would accumulate and fall similar to a snowstorm in both storms, with severe storms causing more sand accumulation than common sand storms.
