Village officials of Downer's Grove were meeting Tuesday evening to discuss possible changes to their siren program.
Many Downers Grove residents complained about the warning system following the large Chicago-area storm on June 21, claiming they had been caught off guard when the second in a series of two EF1-rated tornadoes hit in the western suburb.
"When we had heard the storm come through and that it was in our neighborhood, I was a little shaken by the fact that the village didn't respond in a timely fashion, " said resident Phil Sumida.
Officials said the sirens weren't sounded because the current policy requires a visual confirmation of a funnel cloud or a tornado.
That visual confirmation requirement is expected to be amended.
Storms that came through last week also left quite a dent on the Chicagoland area - literally, for home and car owners.
State Farm Insurance said it has received around 4,000 automotive claims and 600 homeowners' claims as a result of the strong storms that tore through Chicagoland last week. The storms brought golf ball-sized hail in some places.
