Which radars cover Alcova?
The closest NEXRAD Doppler radar is KRIW (Riverton, WY), about 95 miles west-northwest. 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 Alcova | View |
|---|---|---|---|
| KRIW Riverton, WY | 95 mi west-northwest | 8,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCYS Cheyenne, WY | 138 mi southeast | 16,000 ft | Limited — the beam overshoots the lowest part of storms |
| KFTG Denver/Boulder, CO | 222 mi south-southeast | 35,000 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.
