Which radars cover Mammoth Lakes?
The closest NEXRAD Doppler radar is KHNX (San Joaquin Valley, CA), about 97 miles south-southwest. 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 Mammoth Lakes | View |
|---|---|---|---|
| KHNX San Joaquin Valley, CA | 97 mi south-southwest | 9,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KRGX Reno, NV | 149 mi north | 18,000 ft | Limited — the beam overshoots the lowest part of storms |
| KDAX Sacramento, CA | 158 mi west-northwest | 19,800 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.
