Storm
Hurricanes, typhoons, and tornadoes are, often, called storms too but they have special names because they are very, very strong. Storms are studied by scientists called meteorologists. The idea of shipping forecasts started with a concern to save ships from unexpected storms in the North Atlantic. A storm is associated with severe weather and may be marked by strong wind,  thunder, lightning and heavy precipitation such as ice. Therefore, the knowledge of the weather condition is extremely important.
