(click on image to enlarge) |
Summary: A brief tornado touched down near Fairview Avenue and 38th Street in Oak Brook. The first damage was noted along Ridgewood Court and 38th Street, where multiple trees had large branches broken. The tornado moved generally to the southeast, entering Downers Grove near Cumnor Road and 39th Street, where damage was noted to numerous trees. Minor damage was also noted to the cupola of a nearby residence. The tornado moved through the Longmeadow neighborhood, continuing to damage numerous trees. In some areas, the most significant tree damage was noted just above roof level. The tornado slightly intensified near 41st Street and Williams Street, where a few homes had minor roofing damage and numerous trees had large branches broken. Debris from damaged fences was blown in a somewhat convergent pattern toward 41st Street on opposite sides of the street. The tornado appeared to dissipate just southeast of this area as it approached Westmont. The peak wind of this tornado was estimated at 80 mph. This tornado occurred on the northern edge of a much larger area of tree damage associated with straight-line winds. |
The Enhanced Fujita (EF) Scale classifies tornadoes into the following categories:
| EF0 Weak 65-85 mph | EF1 Moderate 86-110 mph | EF2 Significant 111-135 mph | EF3 Severe 136-165 mph | EF4 Extreme 166-200 mph | EF5 Catastrophic 200+ mph |
 | |||||
When a tornado is known to have occurred but does not cause damage to any qualified damage indicators, or if the only damage is located in an area that is inaccessible to NWS storm survey personnel, then a tornado may be assigned the EF-Unknown (EF-U) rating.
Straight-Line Winds
1.) Southeast DuPage County
(click on image to enlarge) |
Summary: A corridor of straight-linewind damage occurred in the Glen Ellyn, Downers Grove, Oak Brook,Westmont, and Clarendon Hills areas. Straight-line winds initially occurred along two corridors approximately one half mile inwidth, the northern area beginning just south of Glen Ellyn andthe southern area beginning south of Morton Arboretum. To theeast, these areas of wind damage merged in northeastern DownersGrove and reached a peak width of approximately 1.5 miles. As thewinds moved to the east, the width narrowed slightly as peak winds decreased, with straight line wind damage appearing to end nearClarendon Hills. Most damage was confined to trees, includingwidespread breaking of twigs and small branches with isolatedlarge branches broken, consistent with peak wind gusts up to 60mph. A few smaller areas experienced more significant wind damage, including a large uprooted tree and numerous large branchesbroken in the Orchard Brook neighborhood of Downers Grove, damageto a church and numerous large branches broken near Downers GroveNorth High School, damage to utility poles and large branchesbroken in the Fairview Avenue subdivision of Downers Grove, anddamage to a utility pole and large branches broken in theBlackhawk Heights subdivision of Westmont and also nearby westernClarendon Hills. Damage in each of these isolated, narrowcorridors was consistent with peak wind gusts up to 70-75 mph. Embedded in the northern edge of this corridor of straight-linewinds was a brief, narrow tornado that impacted areas near the edges of Oak Brook, Downers Grove, and Westmont. However, theoverwhelming majority of damage in the surveyed area was due to straight-line winds. |
