This is the most common type of thunderstorm development. ''Mature thunderstorms'' are found near the center of the cluster, while dissipating thunderstorms exist on their downwind side. ''Multicell storms'' form as clusters of storms but may then evolve into one or more [[squall line]]s. While each cell of the cluster may only last 20&nbsp;minutes, the cluster itself may persist for hours at a time. They often arise from convective updrafts in or near mountain ranges and linear weather boundaries, such as strong cold fronts or troughs of low pressure. These type of storms are stronger than the single-cell storm, yet much weaker than the supercell storm. Hazards with the multicell cluster include moderate-sized hail, flash flooding, and weak tornadoes.<ref name="tsbasics"/>
