Which radars cover Rockville?
The closest NEXRAD Doppler radar is KCLX (Charleston, SC), about 50 miles west. 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 Rockville | View |
|---|---|---|---|
| KCLX Charleston, SC | 50 mi west | 3,500 ft | Good — most storms and steady rain or snow show clearly |
| KCAE Columbia, SC | 107 mi north-northwest | 10,700 ft | Limited — the beam overshoots the lowest part of storms |
| KLTX Wilmington, NC | 140 mi northeast | 16,200 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.
