Derechos are most common along the "corn belt" in the United States, but even where they're most prevalent, there are rarely more than two in a year (compared to 10 to 15 tornadoes a year in the most vulnerable areas). Their rarity is due to the fact that, unlike tornadoes or hurricanes, they're ***t a unified and singular event, but rather an uncommon phe***me***n that was considered ***teworthy e***ugh to be given a name back in 1888. The damage and top wind speed of the derecho often varies along its length because of the fact that it isn't a unified event, but rather a long line of individual downbursts, each with their own microbursts and microclimates.
