Which radars cover Williamston?
The closest NEXRAD Doppler radar is KGSP (Greer, SC), about 23 miles northeast. 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 Williamston | View |
|---|---|---|---|
| KGSP Greer, SC | 23 mi northeast | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KCAE Columbia, SC | 90 mi east-southeast | 8,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMRX Knoxville, TN | 119 mi north-northwest | 12,600 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.
