north central Kansas (KS) and roared eastward causing considerable damage and some
injuries as it crossed northern Kansas, central Missouri (MO), and west central Illinois (IL) (Fig.

(orange "M" in Fig. 1) through the central and northern parts of the Kansas City metropolitan
area (orange "K" in Fig. 1). Measured peak wind gusts included 62 mph at Manhattan, 78 mph
at Topeka (orange "T" in Fig. 1), 90 mph at Lake Perry, KS (orange "P" in Fig. 1), and 78 mph at
Kansas City International Airport. Gusts were estimated to have reached 90 to 100 mph in
several places, including the northern Kansas City suburb of Parkville, MO. Along the most
intense part of the derecho path ("M" to "K"), mobile homes were overturned, buildings were
damaged, planes were overturned at the airports in Topeka and Kansas City, and thousands of
trees were damaged or blown down (Fig 1). Six people were injured in the overturned mobile
homes. Much of the area lost electrical power, including the northern two-thirds of the Kansas
