A downburst wind caused significant tree damage in the southwest section of Keystone Heights, just northwest of Lake Geneva. Damage began near Southeast 42nd Street where large, healthy trees were uprooted and some snapped. A fallen tree damaged a car, and winds lifted and displaced a trampoline 30 feet over a fence. Sporadic tree tops were twisted while others that were still standing indicated a divergent wind pattern. The damage decreased toward the edge of Lake Geneva. The exact cost of tree removal and structural damage was unknown, but the value was estimated.
