Location: WINONA LAKE
Magnitude: 78.00 EG
Property damage: 0.50M

A survey of widespread damage, as well as possible tornado sightings, was performed by NWS officials. A two to three mile wide area of damage was found across the southern part of Warsaw, into much of the Village of Winona Lake. Eyewitness and video footage indicates that a funnel had formed on the leading edge of the storm just prior to the wind damage. No indications of the funnel touching down could be located. However, damage patterns and video footage indicated a downburst occurred. Winds were not fully able to reach the ground, with damage confined to numerous trees being snapped at higher levels or uprooted. Power poles and lines were also knocked down, mainly due to falling trees and tree limbs. Reports of trees falling onto several homes and cars were also received with no injuries noted. Some roof damage was observed in a few locations, including Warsaw Foundry, TTP, Inc. and Whimet, Inc. Winds were estimated between 85 and 90 mph. No specific damage figures were available, but estimates of at least $500,000 are being entered.
