Which radars cover Topaz?
The closest NEXRAD Doppler radar is KRGX (Reno, NV), about 77 miles north. 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 Topaz | View |
|---|---|---|---|
| KRGX Reno, NV | 77 mi north | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDAX Sacramento, CA | 118 mi west | 12,400 ft | Limited — the beam overshoots the lowest part of storms |
| KBBX Beale AFB, CA | 129 mi west-northwest | 14,200 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.
