Which radars cover Iona?
The closest NEXRAD Doppler radar is KSFX (Pocatello, ID), about 48 miles 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 Iona | View |
|---|---|---|---|
| KSFX Pocatello, ID | 48 mi southwest | 3,300 ft | Good — most storms and steady rain or snow show clearly |
| KMTX Salt Lake City, UT | 159 mi south | 19,900 ft | Limited — the beam overshoots the lowest part of storms |
| KRIW Riverton, WY | 177 mi east | 23,700 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.
