Which radars cover Marietta?
The closest NEXRAD Doppler radar is KFFC (Atlanta, GA), about 41 miles south. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Marietta | View |
|---|---|---|---|
| KFFC Atlanta, GA | 41 mi south | 2,700 ft | Excellent — the lowest scan sees close to the ground |
| KHTX Huntsville, AL | 111 mi northwest | 11,200 ft | Limited — the beam overshoots the lowest part of storms |
| KJGX Robins AFB, GA | 112 mi southeast | 11,400 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
