Derecho Storm Smashes Eastern U.S.
Severe weather brought a new word into Americans' meteorological vocabulary in summer 2012. Meteorologists define a "derecho" as a land-based storm that has wind gusts of at least 58 miles per hour and causes damage along a path at least 240 miles long. Eleven states from Illinois to South Carolina and north to New Jersey were affected by a derecho in late June. Winds reached 91 miles per hour -- nearly as fast as winds in a Category Two hurricane. Twenty-eight people died in the storm.
