Which radars cover Sandy Hook?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 65 miles south. 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 Sandy Hook | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 65 mi south | 5,100 ft | Good — most storms and steady rain or snow show clearly |
| KARX La Crosse, WI | 93 mi north-northwest | 8,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMKX Milwaukee/Sullivan, WI | 109 mi east-northeast | 10,900 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.
