Which radars cover Roan Mountain?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 74 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 Roan Mountain | View |
|---|---|---|---|
| KMRX Knoxville, TN | 74 mi west | 6,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGSP Greer, SC | 90 mi south | 8,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KFCX Blacksburg, VA | 115 mi east-northeast | 11,900 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.
