Top Five Extreme Weather Events of Summer of 2012

1. Hurricane Isaac

Last August, the lower Mississippi, the Ohio Valley areas and Florida were hit hard by the brunt of Hurricane Isaac. This Category I hurricane caused multiple home and area evacuations due to its 80 mph winds, pouring rains, widespread flooding and high storm surge.

2. The Super Multi-State Derecho

Forming from last summer's unusual high temperatures, a line of severe thunderstorms accompanied by strong wind gusts and active rain showers (known as a derecho), rampaged across the Midwest and the mid-Atlantic. This now infamous derecho generated more than 30 thunderstorms and its extreme winds brought down power lines, trees and houses. It also took the lives of more than 15 people. Virginia, West Virginia and Ohio were forced to declare state of emergencies in the aftermath of the storm. Millions of residents were left without power for consecutive days, thus making this derecho one of the worst on record.

3. Extreme Heat

From June to August multiple record high temperatures were recorded all over the country as the heat wave seemed never ending. All time records were recorded in Colorado, Kansas and Nebraska. Fort Wayne tied its heat record dating back to the 1930s and Des Moines hit its own record highs previously recorded in the 1950s. Parts of Arkansas, Tennessee and Missouri experienced temperatures nearing 110 degrees. Even the Northeast did not escape the heat and encountered higher temperatures in July.

4. The Midwest & Mississippi Valley Drought

The extreme heat, record high temperatures and lack of rain in the Midwest drastically impacted the corn belt in July and August. The drought all but cooked the corn crop, slowed corn production in the northwestern part of the Corn Belt, especially Iowa and Nebraska, and impacted summer corn prices across the country.

5. Tropical Storm Debbie

Breaking the drought in parts of Florida, tropical storm Debbie hit the northern portion of the state in late June last year. The storm not only nearly drowned several cities and towns with sheer rainfall, like Tampa which received more than 15 inches of rain, but also generated multiple tornadoes in the area.
