False alarms during severe weather can draw the ire of residents, or worse a complacency that causes people to ignore real dangers. So to help people keep a more vigilant mindset when it comes to tornado preparation, the National Weather Service’s Peachtree City office in Georgia is making an effort to lessen the number of tornado false alarms, officials said. Steve Nelson, science and operations officer for the office, said the study is similar to one being conducted at the Birmingham office, both with the same goal: Reduce the number of inaccurate tornado warnings.
