This Hazardous Weather Outlook is for portions of North and Central Georgia.

.DAY ONE...This Afternoon and Tonight...

..A Few Strong Storms Possible This Afternoon and Evening...

A large area of showers and thunderstorms over Alabama was
beginning to move into northwest Georgia. This area will continue

A few of these storms could be strong with gusty winds, pea-sized

Wednesday evening into Wednesday night. Confidence has increased
that at least a portion of the area could see additional isolated
strong to severe thunderstorm activity with strong winds and hail
