Thunderstorms
Thunderstorms are common in Georgia. On average you can expect 45 to 55
days with thunderstorms each year. Personal injury and property damage
can occur as a result of the many hazards thunderstorms produce...including
lightning, hail, damaging wind (downburst or straight line), torrential
flood-producing rainfall, and infrequent tornadoes.
What is a "Severe" Thunderstorm?
These are storms that produce large hail and/or wind gusts strong enough to cause
damage. The National Weather Service has adopted criteria that must be
met before a storm is classified as "severe":
- wind gusts in excess of 57 miles an hour and/or
- hail with a diameter of at least 3/4 inch (the size of
a penny or dime)
If you see hail the size of dimes or
larger, or if you experience wind damage (including downed trees or power lines)...
contact the NWS at (770) 486-1133
or send us a report!
