Which radars cover Irwin?
The closest NEXRAD Doppler radar is KSFX (Pocatello, ID), about 74 miles west-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 Irwin | View |
|---|---|---|---|
| KSFX Pocatello, ID | 74 mi west-southwest | 6,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KRIW Riverton, WY | 143 mi east | 16,800 ft | Limited — the beam overshoots the lowest part of storms |
| KMTX Salt Lake City, UT | 160 mi south-southwest | 20,100 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.
