Which radars cover Gann Valley?
The closest NEXRAD Doppler radar is KABR (Aberdeen, SD), about 102 miles north-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 Gann Valley | View |
|---|---|---|---|
| KABR Aberdeen, SD | 102 mi north-northeast | 9,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KFSD Sioux Falls, SD | 117 mi east-southeast | 12,200 ft | Limited — the beam overshoots the lowest part of storms |
| KLNX North Platte, NE | 164 mi south-southwest | 21,100 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.
