Which radars cover Bon Homme Colony?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 70 miles northeast. 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 Bon Homme Colony | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 70 mi northeast | 5,700 ft | Good — most storms and steady rain or snow show clearly |
