Which radars cover Corunna?
The closest NEXRAD Doppler radar is KDTX (Detroit, MI), about 38 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 Corunna | View |
|---|---|---|---|
| KDTX Detroit, MI | 38 mi east-southeast | 2,500 ft | Excellent — the lowest scan sees close to the ground |
| KGRR Grand Rapids, MI | 73 mi west | 6,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KAPX Gaylord, MI | 136 mi north-northwest | 15,600 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.
