## Overview
The morning of May 12, 2022, began quietly across the Midwest, but by midday, the skies darkened as a powerful serial derecho brought hurricane-force winds exceeding 100 mph across Nebraska, South Dakota, Iowa, Minnesota, and North Dakota. This devastating weather event flattened fields of young corn and soybeans, uprooted trees, and toppled grain silos vital to local economies. With 68 reports of wind gusts over 75 mph, it set a record for a single convective complex. For rural, agriculture-dependent communities, the derecho was catastrophic, destroying crops and irrigation systems while also crippling farming infrastructure. Grain silos—critical for food storage and supply chains—were torn apart, and the economic ripples extended through local and national agricultural markets. The storm laid bare the vulnerabilities of rural America to extreme weather and majorly disrupted the livelihoods of all who depend on food sources from this region.

## What is a Derecho?
Derechos are a type of severe windstorm caused by thunderstorms that move quickly in a straight line over a wide area. Unlike tornadoes, which have rotating winds, derechos produce widespread, powerful winds that can extend for hundreds of miles. The May 12, 2022, event was a serial derecho, a particularly intense type of derecho. Serial derechos occur when multiple clusters of thunderstorms form along a cold front, creating a prolonged impact on the same region. This type of derecho is especially destructive because it produces waves of high winds over an extended area, weakening structures with each round of storms that move through.
