Derecho (pronounced [di-reto]) is a widespread and long-lived windstorm associated with a fast-moving group of thunderstorms known as a squall line. Derechos can cause extensive damage to infrastructure, homes, and businesses, and can also lead to power outages and transportation disruptions.
Derechos are most common in the central and eastern United States, but they can also occur in other parts of the world. They typically form in the spring and summer months, when the atmosphere is unstable and there is a lot of wind shear. Derechos can travel for hundreds of miles, and they can last for several hours.
