Which radars cover Summerville?
The closest NEXRAD Doppler radar is KCLX (Charleston, SC), about 56 miles west-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 Summerville | View |
|---|---|---|---|
| KCLX Charleston, SC | 56 mi west-southwest | 4,100 ft | Good — most storms and steady rain or snow show clearly |
| KCAE Columbia, SC | 85 mi northwest | 7,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLTX Wilmington, NC | 122 mi northeast | 13,000 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.
