Which radars cover Greensburg?
The closest NEXRAD Doppler radar is KHDC (Hammond, LA), about 27 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 Greensburg | View |
|---|---|---|---|
| KHDC Hammond, LA | 27 mi southeast | 1,600 ft | Excellent — the lowest scan sees close to the ground |

| KDGX Jackson, MS | 108 mi north-northeast | 10,800 ft | Limited — the beam overshoots the lowest part of storms |
