The Oklahoma City council approved an update to the city’s outdoor warning siren system on Tuesday that should reduce over-warnings by up to 68 percent and eliminate false warnings.
Oklahoma City has 182 warning sirens that span three counties. Currently, any National Weather Service tornado warning in Oklahoma, Cleveland or Canadian County would activate all the sirens in that county.
Under the new plan, the city is divided into nine sectors. Sirens will only be activated in the sectors that are under threat of a tornado.
