Which radars cover Altura?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 41 miles east-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 Altura | View |
|---|---|---|---|
| KARX La Crosse, WI | 41 mi east-southeast | 2,700 ft | Excellent — the lowest scan sees close to the ground |
| KMPX Minneapolis, MN | 97 mi northwest | 9,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 183 mi south-southeast | 25,200 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.
