Which radars cover Etna?
The closest NEXRAD Doppler radar is KSFX (Pocatello, ID), about 85 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 Etna | View |
|---|---|---|---|
| KSFX Pocatello, ID | 85 mi west | 7,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KRIW Riverton, WY | 128 mi east | 14,100 ft | Limited — the beam overshoots the lowest part of storms |
| KMTX Salt Lake City, UT | 143 mi south-southwest | 16,800 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.
