Which radars cover Gahanna?
The closest NEXRAD Doppler radar is KILN (Wilmington, OH), about 66 miles southwest. 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 Gahanna | View |
|---|---|---|---|
| KILN Wilmington, OH | 66 mi southwest | 5,200 ft | Good — most storms and steady rain or snow show clearly |
| KCLE Cleveland, OH | 109 mi north-northeast | 11,000 ft | Limited — the beam overshoots the lowest part of storms |
| KRLX Charleston, WV | 134 mi south-southeast | 15,200 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.
