Which radars cover Johnstonville?
The closest NEXRAD Doppler radar is KRGX (Reno, NV), about 74 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 Johnstonville | View |
|---|---|---|---|
| KRGX Reno, NV | 74 mi southeast | 6,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KBBX Beale AFB, CA | 82 mi southwest | 7,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDAX Sacramento, CA | 142 mi south-southwest | 16,700 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.
