I can't speak for for 106.7 but WSB seems to only give warnings once counties in "Metro Atlanta" are impacted. Note they never mention Haralson county but as soon as the storm moves into Paulding or Douglas, they start mentioning the warnings. Both those counties are considered metro atlanta and Harlason is not.
Here is a map of what is considered metro atlanta. I think counties are considered part of the metro when a certain percentage of the population in that county travel to Atlanta for work..... I think that's right.
http://commuterclub.com/ acheron82, in some past severe weather events, I do recall News/Talk WSB-AM/WSBB-FM Chief Meteorologist Kirk Mellish occasionally reading the severe weather warning statements for Haralson County as well as other Alabama state line counties such as Chattooga, Floyd, Polk, Carroll, Heard, Troup, & Harris (those counties all in Georgia, not Alabama). Especially, Harris County, because that's where both Callaway Gardens & FDR State Park are located. Each time in the past that Harris County has been issued a warning, Callaway Gardens & FDR State Park have both been in the projected path of the storm. Even though it's not a state line county, I also recall in the past hearing warnings read for Meriwether County. The folks in the extreme Northwest Georgia area across Dade, Walker, & Catoosa counties are rarely covered because of them being close to Chattanooga, TN.
On another note, I've been to the Commuter Club site, and that map is not quite accurate. It doesn't cover all of the Greater Atlanta area. It is understandable if that's all the Commuter Club people can cover. If you want to know how much of North Georgia is included in the Greater Atlanta area, you can go to
http://www.aeroatlas.com/. This, of course, is the website for map company Aero Surveys of Georgia, Inc. Their coverage map is a lot more accurate. That is all.
