Which radars cover Marietta?
The closest NEXRAD Doppler radar is KSHV (Shreveport, LA), about 64 miles southeast. 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 |
|---|---|---|---|
| KSHV Shreveport, LA | 64 mi southeast | 5,000 ft | Good — most storms and steady rain or snow show clearly |
| KSRX Fort Smith, AR | 147 mi north | 17,500 ft | Limited — the beam overshoots the lowest part of storms |
| KFWS Dallas/Fort Worth, TX | 166 mi west-southwest | 21,300 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.
