AJC Investigation: Tornado warnings vary by county

Tornadoes are Georgia’s No. 1 weather-related killer, claiming 23 lives and causing $500 million in damage from 2008 to 2012. But just how much warning you receive before a tornado hits your home depends on where you live.

Last week's deadly storms served notice that spring is the most favorable time of year for a strike, and history shows twister touchdowns are most likely in April.

A survey by The Atlanta Journal-Constitution of more than 30 counties and cities found the systems used by governments to warn residents vary, with some providing no notice of an approaching storm.
