A sandstorm is an unique weather condition available in Grand Theft Auto: San Andreas. They arise when a gust front blows loose sand and dust from a dry surface. It occurs regularly only in the desert or near Las Venturas as it suits the climate. When sandstorms occur, visibility is severely restricted. Clouds of dust can be seen blowing and the sky's color changes to a dull brown. Sandstorms also have a physical impact on flying vehicles (such as fixed-wing aircraft), blowing them hard towards random directions, which can make flying treacherous.
