Which radars cover Merrimac?
The closest NEXRAD Doppler radar is KFCX (Blacksburg, VA), about 14 miles 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 Merrimac | View |
|---|---|---|---|
| KFCX Blacksburg, VA | 14 mi southeast | 800 ft | Excellent — the lowest scan sees close to the ground |
| KRLX Charleston, WV | 105 mi northwest | 10,300 ft | Limited — the beam overshoots the lowest part of storms |
| KRAX Raleigh/Durham, NC | 151 mi southeast | 18,300 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.
