In this report we try to identify the most harmful types of weather events across the United States between 1991 and 2011. We tried to determine if most of the damages/fatalities/injuries are caused only by few types of weather events. We found out that Floods and Hurricanes are most costly type of event meanwhile EXCESSIVE HEAT, FLASH FLOODS, and TORNADOS are most lethal types for the population. If identified correctly it will be helpful to investigate and invest in proper preparation for such events. If a weather event is inevitable, preventing (dealing with) the event consequences should be the priority.
