Which radars cover Unionville?
The closest NEXRAD Doppler radar is KCAE (Columbia, SC), about 85 miles south-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 Unionville | View |
|---|---|---|---|
| KCAE Columbia, SC | 85 mi south-southwest | 7,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGSP Greer, SC | 97 mi west | 9,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KRAX Raleigh/Durham, NC | 121 mi east-northeast | 12,900 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.
