Narrative:
Air carrier X pointed out to ZTL at FL240 sbound. Air carrier Y departed off of sav, handed off to ZTL. ZTL climbed the air carrier Y departure. Air carrier X issued traffic and given immediate turn to avoid. Supplemental information from acn 240780: air carrier X deviating west of course around thunderstorm. Air carrier Y departure, climbing off sav, issued climb by ZTL through air carrier X. Air carrier X issued traffic and turn to avoid.
