Which radars cover Deep River?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 70 miles west. 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 Deep River | View |
|---|---|---|---|
| KDMX Des Moines, IA | 70 mi west | 5,700 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 93 mi east | 8,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 166 mi north-northeast | 21,500 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.
