Derecho Storm: Here are some information about What is Derecho Storm because derecho storm is a widespread, long-lived windstorm associated with a band of rapidly moving showers or thunderstorms. These storms are usually found in the mid-latitudes and can produce winds above 100 mph (160 km/h). Derecho storms can occur anytime but are most common in the summer months. They often affect large areas, sometimes spanning several states. While derecho storms can occur anywhere in the world, they are most common in the United States.

Types of Derecho Storm

There are two types of derecho storm that typically occur in the United States:

  1. Arcus derecho — This type of storm is characterized by a large, bowed shape on radar reflectivity images. Arcus derechos typically form along cold fronts and can produce widespread damage due to their large size.
  2. Mesocyclone derecho — This type of storm is characterized by a small, rotating area of low pressure on radar reflectivity images. Mesocyclone derechos typically form along warm fronts and can be very destructive due to their high winds.

Both derecho storms can produce damaging winds, large hail, and tornadoes. In the United States, derecho storms typically occur during the late spring and summer months.

How can you protect your home and family from derecho damage?
