A statement by the NWS which provides follow-up information on flash flood watches and warnings. As these massively destructive and costly events become more frequent, scientific evidence points to climate change as a leading cause. Dust storms are caused by strong winds that pick up the dust, dirt, and sand from the ground and blow it in thick clouds through the air. Climate-related events last longer or are caused by a buildup of weather-related events over time. Flash floods combine the destructive power of normal floods with incredible speed. There are three main kinds of lightning. The three main types of high clouds are cirrus, cirrostratus, and cirrocumulus. Thunderstorms are usually created via a combination of moisture, atmospheric instability, and lift.
