Which radars cover Iona?
The closest NEXRAD Doppler radar is KFSD (Sioux Falls, SD), about 52 miles west-southwest. 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 Iona | View |
|---|---|---|---|
| KFSD Sioux Falls, SD | 52 mi west-southwest | 3,800 ft | Good — most storms and steady rain or snow show clearly |
| KMPX Minneapolis, MN | 127 mi east-northeast | 13,900 ft | Limited — the beam overshoots the lowest part of storms |
| KABR Aberdeen, SD | 167 mi northwest | 21,700 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.
