The City of Coffeyville will conduct a manual test of its outdoor storm sirens Thursday at noon.

The sirens will sound for about three minutes. City officials say it is only a test, and residents do not need to take any action. A computer system issue continues to prevent the sirens from being activated through the normal system. The sirens remain operational and can be activated manually during an emergency.

Thursday’s test will allow city employees to practice that process. Officials say the three-minute cycle is required when the sirens are activated manually. A technician is expected to repair the computer system within the next several weeks.
