Which radars cover Flat Rock?
The closest NEXRAD Doppler radar is KGSP (Greer, SC), about 30 miles south-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 Flat Rock | View |
|---|---|---|---|
| KGSP Greer, SC | 30 mi south-southeast | 1,800 ft | Excellent — the lowest scan sees close to the ground |
| KMRX Knoxville, TN | 82 mi northwest | 7,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCAE Columbia, SC | 118 mi southeast | 12,500 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.
