Tornadoes are Georgia’s No. 1 weather-related killer. But just how much warning you receive before a tornado hits your home depends on where you live.

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.

Our review found:

• There are limited government standards related to emergency warnings;

• Some governments provide many forms of warnings – from sirens to e-mail alerts, while some have none;

• Experts suggest residents to develop their own tornado emergency plans.

Our tornado package includes an interactive map that shows you how counties and some cities warn residents of approaching storms; how tornadoes develop; and the cost in lives and dollars from recent twisters.
