Which radars cover Castle Rock?
The closest NEXRAD Doppler radar is KFTG (Denver/Boulder, CO), about 33 miles north-northeast. 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 Castle Rock | View |
|---|---|---|---|
| KFTG Denver/Boulder, CO | 33 mi north-northeast | 2,000 ft | Excellent — the lowest scan sees close to the ground |
| KPUX Pueblo, CO | 73 mi south-southeast | 6,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCYS Cheyenne, WY | 123 mi north | 13,200 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.
