BLUFFTON, Ind. (WOWO): The City of Bluffton will issue their tornado sirens Friday as part of Emergency Preparedness Week. The first test will go off at 9:00 A.M., and the second will come at 5:00 P.M. The Bluffton Police Department couldn't say why the sirens are being issued Friday instead of Thursday when the statewide test was issued but said the siren alert was issued by the Mayor of Bluffton. Again, this is just a test.
