Which radars cover Hamilton?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 57 miles northwest. 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 Hamilton | View |
|---|---|---|---|
| KDMX Des Moines, IA | 57 mi northwest | 4,300 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 124 mi east-northeast | 13,400 ft | Limited — the beam overshoots the lowest part of storms |
| KEAX Kansas City, MO | 178 mi south-southwest | 24,100 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.
