ST. CLAIR COUNTY, Ill. (KMOV.com) – Several tornado sirens in St. Clair County will be tested again on Tuesday after they failed last week’s scheduled monthly test.
During last week’s test, none of the sirens in Belleville or Millstadt and only two of Mascoutah’s four sirens worked, according to the Belleville News Democrat. County officials are not speculating what caused the problem but might have a better idea after Tuesday’s tests.
During Tuesday’s tests, engineers will look at the activation site and individual tornado sirens.
St. Clair County does not own the siren system but has the responsibility to active the tornado sirens when a notice is received from the National Weather Service.
Tuesday’s siren test is schedule to begin at 9:30 a.m.
There are more than 30 sirens throughout St. Clair County.
