It forms when winds maintain speeds of at least 93 km/h or 58 mph, the area affected is at least 400 km or 250 miles wide, and it lasts for a minimum of 6 hours. That can cause widespread overall damage and smaller pockets of heavy damage. A warm-weather phenomenon, derechos occur mostly in summer, especially during June, July, and August in the Northern Hemisphere (or March, April, and May in the Southern Hemisphere), within areas of moderately strong instability and moderately strong vertical wind shear. Prior to Hurricane Katrina, the death tolls from derechos and hurricanes were comparable for the United States.

Forecasting the formation of squall lines and derechos can be tricky and difficult. The resultant mesoscale convective system (MCS) often forms at the point of the strongest divergence of the upper-level flow, and new storm cells are developed in the area with the greatest low-level inflow. According to the National Weather Service, the term comes from the Spanish word "derecho," meaning "direct" or "straight ahead," and was first used in 1888 by a chemist and professor of science. Therefore, the most favorable area for this type of storm to develop is on the periphery of a strong area of high pressure aloft where the greatest overlap of hot and dry conditions and stronger wind aloft occurs.
